Given what is known about the minimal essential functions of cellular life, if you could create an artificial cell, which of the following structures must you include?
a. nucleus
b. ribosome
c. cell wall
d. mitochondria
Answers
To create an artificial cell, you must include ribosomes. The correct option is (b).
Artificial cells have been created that mimic the essential functions of living cells. This has allowed scientists to study the fundamentals of life without relying on the natural environment. There are a number of structures that must be present in an artificial cell to make it viable.
It includes a lipid bilayer, which can form a boundary between the inside and outside of the cell. Artificial cells must also be able to communicate with one another, which requires a system of proteins and enzymes. To perform these functions, artificial cells also need energy.
This can come from a number of sources, such as light, glucose, or other chemical compounds. Artificial cells also need to be able to synthesize proteins, which is why ribosomes are required in them. The ribosome is responsible for translating RNA into protein, which is a fundamental step in the process of building a living cell.
There are other structures that could also be included in an artificial cell. For example, mitochondria are responsible for energy production in natural cells. However, they are not necessary for an artificial cell to function. Similarly, a cell wall is not necessary for an artificial cell, as it is not present in all types of living cells.
Therefore, the correct answer is option B.

Did dinosaurs and humans exist at the same time? What is your evidence?
Answers
Answer:
No! Humans took 65 million years to arrive on the globe after the dinosaurs died out. During the dinosaur period, small mammals such as shrew-sized primates existed.
Explanation:
Hope this helps you!!!!! :D
Of course the ancestors of humans were contemporary with the dinosaurs. Yes, they were alive some 65 million years ago, BUT you wouldn't recognize them as human. Our ancestors back then were little furry creatures with tails, about the size of a rat. Close inspection might have revealed that even back then they had some human like features. They probably had forward directed eyes to give them binocular vision. They could possIbly see in colour. They would have had 5 digits on each limb as we do. They probably had approximately the same number of teeth as we do. They most definitely had warm blood, nipples and fed their young on milk. They possibly had nails rather than claws.
Now, great big creatures with enormous bones like dinosaurs, whales and mammoths, fossilize well, but creatures with small fragile skeletons like hummingbirds, bats, mice, shrews and the ancient shrew like ancestors of humans would be fantastically lucky to be fossilized at all. Their little carcasses would be eaten by predators or scavengers, by ants, maggots and beetles. Only a fool would hope ever to find a fossil of one of our direct ancestors from the time of the dinosaurs, but that doesn't mean they didn't exist. We know they existed because we exist today. Remember, all forms of life present today, have always existed at every time in the past, but not necessarily in a shape we would instantly recognize as ancestral to their present form

state the relationship between cell function and cell structure?
Answers
Answer: The structure of the cell depends on what type of function it performs. The organisms can only function properly if the structure goes along with the function it is to perform.
Cell function and cell structure are intimately related. The specific structure of a cell determines its function or the tasks it can carry out. For example, a muscle cell has a unique structure with many contractile proteins that allow it to generate force and movement, whereas a nerve cell has a unique structure with long, branching extensions that allow it to transmit signals over long distances.
The cell's structure is designed to support its function. Different types of cells have different structures that are adapted to carry out specific tasks. For example, red blood cells are specialized to carry oxygen and have a unique biconcave shape that allows them to flow easily through narrow blood vessels. Similarly, the shape and structure of a leaf cell are adapted to maximize photosynthesis and energy production, while the structure of a bone cell is adapted to provide strength and support to the body.
Therefore, the structure of a cell is closely related to its function, and changes in cell structure can affect its function. For example, changes in the shape or structure of a muscle cell can affect its ability to generate force and movement. Similarly, changes in the structure of a nerve cell can affect its ability to transmit signals effectively. Understanding the relationship between cell function and structure is critical in understanding how cells work and in developing new therapies for diseases that affect cell structure and function.

In the mouse model of malaria, the researchers injected Plasmodium-infected human red blood cells into the mice because the Plasmodium species had surface ligand proteins that bound only to the cell membrane proteins of human red blood cells. Assume that the researchers noticed that some of the parasites no longer infected human red blood cells but instead infected mouse red blood cells. Predict the most likely cause of this change in the host specificity of the parasites.
Answers
Genetic mutation is the most likely cause of the change in host specificity of the Plasmodium parasites.
It is possible that the Plasmodium parasites underwent genetic changes that enabled them to bind to the membrane proteins of mouse red blood cells. These changes may have occurred randomly or as a result of selective pressure in the mice.
It is also possible that the Plasmodium parasites acquired genetic material from other parasites that infect mice, which allowed them to expand their host range.
Another possible explanation is that the Plasmodium parasites were able to adapt to the mouse environment and develop new mechanisms to invade mouse red blood cells.
This could have happened due to the mice providing a more favorable environment for the parasites to multiply, resulting in the selection of parasites that were better adapted to the mouse host.
In summary, the change in host specificity of the Plasmodium parasites is most likely due to genetic mutation or adaptation to the new host environment.

Answers
As temperature increases, the rates of chemical reactions and the growth of fungi and bacteria increase.
However, the rate of these reactions and the growth of fungi and bacteria will decrease as the temperature increases past a certain point. The rate of these reactions and the growth of fungi and bacteria is controlled by enzymes, which have optimal temperatures at which they function best. Outside of this optimal range, enzymes will become less efficient and the reaction rate will slow down.Therefore, high temperature is not always favorable for chemical reactions and the growth of fungi and bacteria.

During the entire process of meiosis in humans (n=23) what is the highest and lowest number of total complete strands of DNA in an individual cell? (hint, each chromosome or sister chromatid is made up of a single complete strand of DNA).
Group of answer choices
Highest: 46 | Lowest: 23
Highest: 46 | Lowest: 46
Highest: 92 | Lowest: 46
Highest: 184 | Lowest: 23
Highest: 92 | Lowest: 23
Answers
During the entire process of meiosis in humans (n=23), the highest and lowest number of total complete strands of DNA in an individual cell are: Highest: 92 | Lowest: 23. The correct option is e.
Meiosis is a process of nuclear division in eukaryotic cells that results in four haploid daughter cells. These haploid cells differ genetically from the parent cell that produced them because of the recombination and independent assortment of chromosomes that occur during meiosis.
During meiosis in humans (n=23), the highest and lowest number of total complete strands of DNA in an individual cell are as follows:1. Highest: 92In a human cell at the end of the S phase, there are 46 double-stranded chromosomes. Each double-stranded chromosome is composed of two sister chromatids, which contain a complete strand of DNA. During prophase I of meiosis, each chromosome in the parent cell aligns with a homologous chromosome to form a bivalent or tetrad. As a result, each chromosome in the daughter cell contains a complete strand of DNA from both the mother and the father.
As a result, each daughter cell produced during meiosis in humans contains 23 double-stranded chromosomes, with a total of 92 complete strands of DNA.2. Lowest: 23The primary function of meiosis in humans is to produce gametes (sperm and eggs) that are genetically unique. The production of haploid gametes necessitates a reduction in the number of chromosomes.
During the first meiotic division, the number of chromosomes in the parent cell is reduced by half, resulting in two haploid daughter cells. Each daughter cell contains 23 single-stranded chromosomes, with a total of 23 complete strands of DNA. The second meiotic division is similar to mitosis in that it separates the sister chromatids of each chromosome, resulting in four haploid daughter cells, each containing 23 single-stranded chromosomes.

Select all the anticodons that could bind to the codon for serine. Choose all that apply. Check All That Apply -5-AGA-3 -5-GGA-3
-5-AGG-3
-5-IGA-3
-5-AGI-3
-5-UGA-3
Answers
None of the given options match the possible anticodons for serine, so the answer is none of the above.
The genetic code is the set of rules that specify the relationship between the sequence of nucleotides in DNA or RNA and the sequence of amino acids in a protein. In the genetic code, each amino acid is specified by a sequence of three nucleotides, called a codon. For example, the codon "AGU" specifies the amino acid serine.
In the process of translation, the codon in the mRNA is recognized by a complementary sequence of three nucleotides in a transfer RNA (tRNA) molecule, called an anticodon. The anticodon of the tRNA pairs with the codon of the mRNA through base-pairing rules, with adenine (A) pairing with uracil (U) and guanine (G) pairing with cytosine (C).
Based on this, we can determine the possible anticodons that could bind to the codon for serine ("AGU") by applying the base-pairing rules. The possible anticodons are 5-UCU-3, 5-CCU-3, 5-UCG-3, and 5-CCG-3.
None of the given options match the possible anticodons for serine, so the answer is none of the above.

Answer:
The difference between light reaction and dark reaction
Explanation:
Light reaction and dark reaction are the two types of sequential processes that occur during the photosynthesis of plants. Light reaction occurs in the thylakoid membrane of chloroplast whereas the dark reaction occurs in the stroma of the chloroplast. Light energy from sunlight is trapped by chlorophylls during the light reaction of the photosynthesis. Dark reaction is catalyzed by various enzymes. The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light reaction.
Dr. Dixon calls Vitamin A/Retinoids the most powerful molecules in the Universe. He calls them this because they are involved in
Answers
While Vitamin A/Retinoids are not actually the most powerful molecules in the universe, they are certainly important for a variety of biological processes in many organisms, including humans. One reason why they are considered important is that they are involved in a variety of critical biological functions, including vision, gene transcription, and cellular differentiation.
Vision: Vitamin A is a key component of the visual cycle, which is the process by which light is converted into neural signals that are transmitted to the brain. Specifically, Vitamin A is a component of rhodopsin, a protein found in rod cells in the retina that is responsible for detecting light. Without adequate levels of Vitamin A, the visual cycle cannot function properly, which can lead to vision impairment or blindness.
Gene transcription: Retinoids also play a key role in regulating gene expression, or the process by which genes are "turned on" or "turned off" in response to different stimuli. Specifically, retinoids bind to nuclear receptors in the nucleus of cells, which then bind to DNA and regulate the transcription of various genes. This process is involved in many critical biological processes, including cell differentiation, growth, and development.
Cellular differentiation: Vitamin A is also important for cellular differentiation, or the process by which immature cells become specialized and assume specific functions. Specifically, retinoids are involved in the differentiation of epithelial cells, which line the surfaces of organs and tissues throughout the body. This process is particularly important for the development and maintenance of healthy skin, mucous membranes, and other tissues.
Overall, while Vitamin A/Retinoids may not be the most powerful molecules in the universe, they are certainly important for many critical biological processes in humans and other organisms.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answers
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide

What is a limitation of the bell jar model when modelling ventilation?
Answers
One limitation of the bell jar model when modeling ventilation is its oversimplified representation of real-world conditions. The bell jar model assumes a uniform and consistent distribution of airflow within the enclosed space, disregarding factors such as complex air currents, turbulence, and variations in temperature and humidity. In reality, ventilation dynamics are influenced by a range of factors, including room geometry, furniture placement, and occupancy patterns, which cannot be accurately captured by the simplistic bell jar model. This oversimplification may lead to inaccurate predictions or underestimation of ventilation rates in real-life scenarios.
Another limitation is the lack of consideration for external influences on ventilation. The bell jar model typically assumes a closed system, neglecting the impact of external factors such as wind, temperature differentials, and outdoor air quality. In real environments, these external influences play a crucial role in ventilation dynamics. Wind direction and speed, for instance, can significantly affect the inflow and outflow of air in a building. Temperature differences between indoor and outdoor environments can drive natural ventilation processes. Ignoring these external factors in the bell jar model may result in unrealistic estimations of ventilation rates and limit its applicability to real-world scenarios.
