How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan
Answer:
18 molecules of \(CO_{2}\)
Explanation:
In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.
In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
For 3 molecules of glucose, multiply the number of reactants and products...
(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3
Thus...
3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

To extract these deep ocean creatures and make use of their special abilities that can be used as an energy source. The use of deep mining projects can extract many unknown hidden resources that are potential for the future. The corals that live on the ocean floor are also a potential resource for man in the future.A crane has a sharp and pointed beak while the duck has a flat beak.Explain why
Answer:
The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.
On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.
The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.
The image shows an energy pyramid. Vulture Coyote Prairie dog Grass Which statement about how energy flows through this ecosystem is supported by this ecological pyramid? OA. The highest trophic level has the most available energy because vultures are a tertiary consumer. B. The organisms of the second trophic level obtain their energy from the coyotes located in the third trophic level. C. The grasses' trophic level has the most energy, but only some of that energy moves to the second trophic level. D. The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.
The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).
The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.
In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.
Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.
The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.
Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.
Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.
Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

(b) discuss the advantages of using Artificial Insemination (Al) compared with the natural service of the female animal. [6]
Translocation in plants describes the transfer of substances from one area of the plant to another, including water, minerals, and sugars.
Translocation in plants, and artificial inseminationTranslocation in plants describes the transfer of substances from one area of the plant to another, including water, minerals, and sugars. The vascular system of the plant, which comprises the xylem and phloem, is where this movement takes place. Phloem transports sugars and other organic molecules from the leaves to other parts of the plant, whereas xylem is in charge of moving water and minerals downward from the roots to the leaves.
Systemic pesticides are substances that can be sprayed on a plant's soil, leaves, or seeds and then absorbed by the vascular system of the plant to kill pests that feed on it. Neonicotinoid insecticides, for instance, can be used to manage aphids in crops.
Artificial insemination (AI) has benefits over natural insemination for female animals, including the use of superior genetics without the need to physically transfer or lodge a male animal. Without the possibility of inbreeding or genetic abnormalities that can occur with natural selection, AI enables the selection of the finest genetic features, like as milk production or disease resistance.

5) Draw a pedigree chart: Milhouse van Houten has a round nose. Milhouse thinks that he must have been given to the wrong parents in the hospital because both of his parents and his little
sister, Milcasa, have stubby noses. At the last van Houten family reunion Milhouse noticed that
his grandmothers both have stubby noses but that his grandfathers both have round noses.
Assuming that Milhouse was not given to the wrong parents in the hospital create a pedigree table
including the 8 family members described. Is having a stubby nose trait dominant or recessive?
How can you tell?
They have the genotypes RR, Rr, and rr. There are two phenotypes: square and round noses.
In order to blend in with the band, Milhouse is under pressure from the band to alter his physical appearance and attire. It is a prime illustration of conformity. In psychology, conformity is the social pressure that an individual feels as a result of peer pressure. It is a modification of beliefs made to fit into a social role.
The genotypes and phenotypes of the offspring can be discovered using the genotypes of the parents and a punnett square. When heterozygous refers to a different genotype, we are aware of the parent's genotypes, which are Rr. They produce the genotypes RR, RR, Rr, and rr when they are crossed. The recessive gene is replaced by the dominant gene, which is capitalised. The round nose is a dominant trait. As a result, there are both round and square phenotypes.

HELP ME Which of the following is expected to decrease due to climate change?
A. Freshwater
B. Flooding
C. Sea levels
D. Temperatures
The correct option from the given question is option A) Freshwater is expected to decrease due to climate change.
Explanation:
Climate change refers to the long-term changes in the average weather patterns that have come to define Earth’s local, regional, and global climates. Climate change is primarily due to the increase in atmospheric concentrations of greenhouse gases (GHGs) produced by human activities, such as burning fossil fuels and deforestation.
Climate change has numerous consequences on the planet, including rising temperatures, sea level rise, increased frequency, and severity of extreme weather events, and changes in precipitation patterns, all of which have significant impacts on human societies and ecosystems.
Among the given options, freshwater is expected to decrease due to climate change. Climate change alters precipitation patterns, resulting in more frequent and severe droughts in some regions and increased flooding in others, resulting in water shortages. Higher temperatures and evaporation rates result in drier soils, which reduces water availability. These factors can reduce the amount of freshwater available for human consumption, agriculture, and other purposes.

_________are living cells that do not conduct sugar themselves.
Answer:
Companion cells
Explanation:
Companion cells are important structures found in the vascular bundle known as the phloem of plants. They work together with sieve cells in the movement of vital compounds such as Protein, ATP etc to other parts of the plant.
Companion cells are also known as living cells that do not conduct sugar themselves but they play a very important role in the movement of these substances.
Companion cells are living cells that supply ATP, protein and other nutrients to the sieve elements but do not conduct sugar themselves.
Companion cells are parenchymal cells found within the phloem that direct the flow of nutrients through the sieve tubes, which do not have the cellular maintenance structures.
The elements of the sieve depend on the companion cells to do much of the metabolic work required to transport sugars and other nutrients.Therefore, we can conclude that companion cells are highly specialized parenchymal cells that support the sieve elements in the transfer of sugars in the plant.
