What two body systems will work together to provide cells with energy?
A. Excretory and Digestive, because the nutrients from the digested food will be sent to the excretory to be delivered out as waste products.
B. Digestive and Muscular, because the nutrients from the digested food will be used immediately by the muscles for energy.
C. Respiratory and Excretory, because the oxygen will be transported to the cells so that wastes can be delivered out as a waste production.
D. Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Answers
Answer:
Answer:
The correct answer for the first question would be B) the respiratory and circulatory systems.
Respiratory system is a set of organs which help in exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to outside world. The exchange of the gases takes place at alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
The correct answer of the second question would be C)the digestive and circulatory systems.
Digestive system helps in breaking down of macro-molecules (such as starch, polypeptide, fats) into smaller units (such as glucose, fructose, amino acids) as well as absorption of the same.
Nutrients from the absorptive site (usually small intestine) are then transported to the entire body with the help of blood through capillaries and arteries that is, circulatory system.
Explanation:
Body systems that will work together to provide cells with energy are:-Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Digestive system will breakdown complex macromolecules into micro molecules which are then transferred into blood.Blood or Cardiovascular system will carry these micro nutrients to different parts of the body Describe digestive system?It is system that include organs that take in food and liquids and break them down into substances that the body can use for energy.
Describe cardio vascular systemThe circulatory system or cardiovascular system pumps blood from the heart to the lung to get oxygen.

Which kind of diet helps prevent cancer
Answers
A diet high in fruits, vegetables, and whole grains, that is low in processed foods, red and processed meats, and refined grains, is associated with a decreased risk of cancer.
Nutritious diet that includes a variety of fruits, vegetables, and whole grains includes key vitamins and minerals, as well as fiber and other important nutrients that can boost your body's defense against cancer. Eating a diet high in red and processed meats, as well as refined grains, on the other hand, may increase inflammation and free radicals, which may increase risk of certain types of cancer.
The scientific evidence for a correlation between diet and cancer prevention is supported by numerous studies. For example, a 2007 prospective study of over 50,000 people found that individuals with diets rich in fruits, vegetables and whole grains were 20% less likely to develop cancer than those who ate less of those foods. Other epidemiological evidence, as well as laboratory and animal studies, suggests that certain nutrients found in these foods (including natural antioxidants and phytochemicals) may play a role in decreasing cancer risk.

Answers
The explanation of the vocabulary terms include:
Dichotomous Key: A tool used in biology to identify organisms by their characteristics, which can be used to narrow down a list of possibilities through a series of choices.
Phylogeny: The evolutionary history of a group of organisms.
Evolution: The process by which populations of living organisms change over time through natural selection, genetic drift, and other mechanisms, leading to the emergence of new species.
Charles Darwin: A British naturalist who proposed the theory of evolution by natural selection and is considered one of the most important figures in the history of science.
Linnaeus: A Swedish botanist and zoologist, who laid the foundations for the modern system of naming organisms called binomial nomenclature.
Binomial Nomenclature: A system of naming organisms using two Latin names, the first representing the genus and the second representing the species.
Homologous Structures: Structures in different organisms that have a similar underlying structure and development, but may have different functions, suggesting they have a common ancestor.
Analogous Structures: Structures in different organisms that have similar functions but a different underlying structure and development, suggesting they have evolved independently.
Vestigial Structures: Structures in organisms that have little or no function in the organism, but have a function in an organism's ancestors
Fossil Record: The remains or traces of organisms from the past, which can provide evidence for the existence and evolution of extinct species.
Comparative Embryology: The study of the developmental stages of different organisms, which can provide evidence for common ancestry.
Biogeography: The study of the distribution of living organisms and fossils across different regions and through time, which can provide evidence for the evolution of species.
Molecular Biology: The study of the molecular basis of biological activity, which can provide evidence for evolutionary relationships between species through the comparison of DNA and protein sequences.
Transitional Organism: An organism that shows characteristics intermediate between two different groups, suggesting it is a link in the evolutionary chain between them.
Anatomy: The study of the structure and organization of living organisms, which can provide evidence for evolutionary relationships between species.
Common Ancestor: A hypothetical ancestor from which two or more species have evolved, inferred from the similarities and differences in their characteristics.
How to explain the vocabulary?To claim an evolutionary relationship between species, scientists use a combination of evidence from paleontology, comparative anatomy, molecular biology and biogeography. For example, the discovery of transitional fossils that show a gradual transition between the characteristics of two different groups of species, the similarities and differences in the DNA sequences of different species, the similarities in the embryological development of different organisms and the distribution of different species in different regions can provide evidence of evolutionary relationships between species.
Homologous structures are structures in different organisms that have a similar underlying structure and development, but may have different functions. These structures provide evidence for common ancestry because they suggest that the organisms with these structures share a recent common ancestor. Examples of homologous structures include the forelimbs of mammals, birds, and reptiles, which all have the same basic bone structure, despite being adapted for different purposes such as flight, grasping, or digging.

What is the primary function of stems?; How does auxin produce Phototropism?; How mitosis occurs in growth of seedlings?; Is the process by which internal environments of an organism are regulated?
Answers
Stem supports branches, leaves, flowers, and fruits. It transports water and minerals from the roots to the leaves and other parts of plants. It transports food from leaves to different parts of the plant. It holds the plant upright.Auxin has a role in phototropism, responding to light.
Auxin has a role in phototropism, responding to light. Auxin is produced by cells in the apical meristem. The direction of light is detected at the tip of the shoot by pigments called phototropins. Phototropins stimulated by the absorption of light regulate the transport of auxin. When a shoot is exposed to light from above, auxin efflux pumps are located at the base of the cells in the shoot apex.
Auxin is transported downwards from the meristem, and has an equal distribution in the cells below the meristem. The cells elongate and the shoot grows straight upwards, symmetric growth. When the shoot is exposed to light from one side, this causes auxin efflux pumps to change location inside the cell. They move to the side of the cell furthest away from the light. This causes auxin to be transported to the shady part of the root, generating a higher concentration of auxin on the shady side than on the side exposed to light. This causes more cells on the shady side to elongate and the shoot bends towards the light, asymmetric growth.
Homeostasis is the process by which internal environments of an organism are regulated.

Why is it more ecological friendly to eat a salad than a steak?
Answers
People may help reduce their environmental impact, conserve resources, and mitigate environmental problems related to intensive animal production by making salads their meal of choice.
Thus, due to a number of variables, eating a salad is more environmentally friendly than eating a steak. First, compared to plant-based meals like vegetables and grains, the production of meat, especially beef, takes much more resources including water, land, and feed.
This suggests a bigger environmental impact and more demand on natural resources. The cattle sector also contributes to water pollution, greenhouse gas emissions, and deforestation. Salads, on the other hand, promote the consumption of plant-based meals, which often have less of an impact on the environment.

One of the most common plants in Atlantic salt marshes is cordgrass. Periwinkle snails cling to the top of tall cordgrasses during high tide. The tall cordgrasses provide protection from the snails’ predators, such as the blue crab. While the snails do not feed directly on the cordgrass, the snails can damage the cordgrass when they graze on algae and fungi that grow on the grasses. If the snail population grows too large, it can decrease cordgrass growth.

Answers
Answer:

Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.
What is biotic factor?Biotic factor is defined as the live elements or factors that have an impact on an environment or other organisms residing there. A particular ecosystem is the result of the interaction of biotic and abiotic components. Anything that can be used as fuel to encourage bacterial development or is a bacteria itself is referred to as a biotic supplement.
In most salt marshes, periwinkle snails can be seen grazing on the cordgrass just above the water line. They mostly focus on the fungi that inhabit the grass, not much of the actual grass itself. But because they munch on the grass, the fungi can spread further throughout the plants.
Thus, Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).
What is the nitrogen cycle?Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.
The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

4. The endocrine functions is stimulated by this hormone in the anterior pituitary _____ and produces this in the male_____
Answers
1. The exocrine function is stimulated by this hormone produced in the anterior pituitary: follicle-stimulating hormone (FSH), and produces ova (eggs) in the female.
2. The endocrine function is stimulated by this hormone in the anterior pituitary: luteinizing hormone (LH), and produces estrogen and progesterone in the female.
3. The exocrine function is stimulated by this hormone produced in the anterior pituitary: luteinizing hormone (LH), and produces sperm in the male.
4. The endocrine function is stimulated by this hormone in the anterior pituitary: follicle-stimulating hormone (FSH), and produces testosterone in the male.
1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.
2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.
3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.
4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.
Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.

Congratulations! In vitro fertilization was a success. You and your partner are now waiting for the arrival of your baby. If a gamete from Donor B was used, what is the chance/probability that your baby will have no freckles (rr) AND wavy hair (T'T)? Donor B is heterozygous for the hair trait while you have curly hair (see class notes for curly hair genotype). Below, make your punnett square(s) for this question and be sure to use the correct allele notation for our lecture class. Once you made your punnett square(s) talk with some groups around you (or with Dr. Cline-Brown) to check if you are all on the right track.
Answers
The probability of having a baby with no freckles and wavy hair, given that a gamete from Donor B was used, is 25%.
What is probability?
Based on the information provided, we know that Donor B is heterozygous for the hair trait (T'T) while you have curly hair (TT). We also know that the trait for freckles is recessive (r).
To determine the probability of having a baby with no freckles (rr) and wavy hair (T'T), we need to create a Punnett square using the gametes from Donor B and your partner.
Donor B:
T' T
. .
T' T'T'
T TT
Partner:
T T
. .
T TT
T TT
Combining the gametes, we get the following Punnett square:
T' T
T T'T TT
T T'T TT
From the Punnett square, we can see that there is a 25% chance of having a baby with no freckles (rr) and wavy hair (T'T), as this combination only appears in the bottom left cell of the Punnett square.
Therefore, the probability of having a baby with no freckles and wavy hair, given that a gamete from Donor B was used, is 25%.

https://brainly.com/question/30034780
#SPJ1
Assuming that freckles and wavy/curly hair are determined by different genes, we can consider them independently. Let's first focus on the hair trait.
Donor B is heterozygous for the hair trait, which we can represent as T'T. You have curly hair, which we can represent as TT. Therefore, your genotype for hair is TT.
To determine the probability of your baby having no freckles (rr) and wavy hair (T'T), we need to create a Punnett square for the cross between Donor B and you.
The Punnett square for the hair trait is:
r
T' T
T' T'T' T'T
T T'T TT
Since Donor B is heterozygous for the hair trait, we have two possible gametes: T' and T. Since you have the genotype TT, you can only contribute a T gamete.
Now, let's consider the freckles trait. We don't know your genotype for this trait, so let's assume that you are heterozygous (Rr) and that Donor B is homozygous recessive (rr). This gives us the following Punnett square for the freckles trait:
R r
r rr Rr
r rr Rr
Now, we can combine the Punnett squares for the hair and freckles traits to determine the probability of having a baby with no freckles (rr) and wavy hair (T'T):
r
T' T
T' T'T' T'T
T T'T TT
R r
r rr Rr
r rr Rr
To get the probability of having a baby with no freckles and wavy hair, we need to look at the offspring that are T'T and rr. There are two possible genotypes for these offspring: T'T'rr and TTrr.
Therefore, the probability of having a baby with no freckles and wavy hair is:
P(T'T'rr) + P(TTrr) = (1/4) + (1/4) = 1/2 or 50%
So there is a 50% chance that your baby will have no freckles and wavy hair if a gamete from Donor B was used, assuming that freckles and hair are determined by different genes and that you are heterozygous for the freckles trait.
What is punnett square
The Punnett square consists of a grid with two rows and two columns, representing the possible alleles (versions of a gene) contributed by each parent. The alleles are written along the top and side of the grid, and the boxes in the grid represent the possible genotypes (combination of alleles) of the offspring.
What is heterozygous
Heterozygous refers to having two different alleles (versions) of a particular gene. In other words, a heterozygous individual inherits two different versions of a gene, one from each parent.
