Answer:
1) carbon dioxide, water, and sunlight.
2) glucose and Oxygen, and humans got benefited by consuming (breathing oxygen) that are produced by plants while photosynthesis.
3)During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

b. the use of RuBisCO to form 3-PGA
c. the production of carbohydrate molecules from G3P
d. the formation of RuBP from G3P molecules
e. the use of ATP and NADPH to reduce CO2
Answer:
answer A the conversion of CO2 to an organic compound.
Explanation:
Carbon fixation is first step of Calvin cycle. The carbon fixation is process during which inorganic CO2 gas into organic compounds.
The carbon fixation does not involve usage of RuBisCO to form 3-PGA. This step will take place during regeneration process of Calvin cycle.
Carbon fixation refers to the conversion of carbon dioxide to an organic compound.
What is carbon fixation?It is the process by which autotrophs fix atmospheric carbon to produce organic compounds. It is the assimilation of inorganic carbon and its transformation to organic compounds. This can be used as the storage of energy and for the production of biomolecules.
All the autotrophs fix atmospheric carbon dioxide by the phenomenon of chemosynthesis or photosynthesis. The main process of carbon fixation is the photosynthesis. The process of carbon fixation takes place in the light-independent reaction or dark reaction of the process of photosynthesis.

Explain the flow of blood from a leg muscle to the heart and lungs and back to the muscle again listing each organ the blood travels through and what happens at eavh place
Deoxygenated blood from the leg muscle returns to the heart, moves to the lungs to be oxygenated, goes back to the heart, and flows through the body again.
The circulatory system is a complex system in the body whose function is to keep the flow of oxygenated blood throughout the body.
This system is composed of multiple steps that create a cycle and usually involve the following organs:
The heart.The lungs.Blood vessels.VeinsArteriesHere are the steps if we start with deoxygenated blood in the muscles.
The deoxygenated blood returns to the heart through the veins. This blood has no oxygen because this has been used.An important vein known as the vena cava pumps the blood into the right atrium of the heart.The blood then floods into the right ventricle.Later, as the heart beats the blood moves from the heart to the pulmonary artery.In the lungs, the blood is oxygenated and then it returns to the heart.The blood goes to the left atrium and moves to the left ventricle.The blood is pumped from the heart to the rest of the body including muscles.Learn more about blood in: https://brainly.com/question/11568067
the ________ is vital to sleep because it secretes growth hormones.
Answer:
The pituitary gland
The pituitary gland is vital to sleep because it secretes growth hormones. Sleep is essential for growth because it triggers the release of several hormones.
How pituitary gland secrets the growth hormones?Our brain's pituitary gland is a structure that creates specialized hormones, including growth hormone (also referred to as human growth hormone or HGH). Growth hormone (GH) is released in pulses during the course of a 24-hour cycle.
Early sleep, in temporal conjunction with the beginning of the first period of deep slow-wave sleep, is when normal adult participants have the most consistent and frequently largest GH pulse (SWS).
Therefore, sleep, stress, exercise, and low blood glucose levels all raise growth hormone levels, released by the pituitary gland.

Which of the following would increase species biodiversity in Florida?
A.
Placing no limits on alligator hunting in lakes
B.
Legalized hunting for monkeys around the St. John’s River
C.
Protecting black bears in state or national forests
D.
Clearing land for a new entertainment theme park
Answer:
C
Explanation:
Biodiversity measures the variety of organisms in an ecosystem. Allowing hunters to hunt alligators depletes the alligator population which decreases biodiversity. Legalizing monkey hunting depletes the population which decreases bio diversity. Deforestization rids animals of their habitats which massively decreases biodiversity due to the plants, trees, and animals destroyed in the process. That and the fact that there will be less sites for nesting and homes for the animals which will decrease biodiversity even more over time. It's all connected.
Protecting a species conserves the population and ensures the safety of the animal especially from human interference. This allows the animal (specifically the black bear) to survive in its habitat unharmed and allows it to play its role in the ecosystem and contribute to biodiversity.

If you start with 60 chromosomes and end with 60 chromosomes
If you start with 60 and end with 60, then no change has occurred. Mitosis is part of cell replication, so if we end with the same number as we started with, then no form of mitosis has occurred.
I hope this helps! :)
If we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.
What is Mitosis?Chromosomes that have been duplicated are splitting into two new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.
Mitosis is a process used to create more cells that share the same genetic makeup as the parent cell. It is essential to the expansion and development of human bodies as well as for the embryonic development of living things. Mitosis generates new cells and replaces injured, destroyed, or ageing ones.
Thus, if we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.

Which two organisms are most closely related, based on the tree above?
ray-finned fishes and sharks
rodents and primates
dinosaurs and crocodiles
dinosaurs and birds
Answer:
dinosaurs and birds
The two organisms that are most closely related are dinosaurs and birds.
Why are organisms related?Organisms are related because they share a common ancestry, meaning they have evolved from a common ancestor through genetic and evolutionary changes over time.
Based on the tree above, the two organisms that are most closely related are dinosaurs and birds. This is because birds are descended from a group of small, feathered dinosaurs that lived during the late Jurassic period, and are therefore considered to be a type of dinosaur.
The branch point where birds diverge from other dinosaurs is relatively recent on the tree, indicating that they share a more recent common ancestor than other organisms on the tree. In contrast, ray-finned fishes and sharks, rodents and primates, and dinosaurs and crocodiles diverged from each other at earlier points in evolutionary history, indicating that they are less closely related to each other than dinosaurs and birds.

In this case, the organism would not be able to produce ATP in aerobic conditions. The Krebs cycle is fundamental in humans.
Cellular respiration consists of a series of metabolic reactions by which aerobic cells can produce ATP (the energy coin of the cell) by using the energy stored in foods and oxygen.
Cellular respiration has three types of sequential reactions: glycolysis, the Krebs cycle and oxidative phosphorylation.
During the Krebs cycle, the energy from foods (e.g., carbohydrates) is released through the oxidation of acetyl-CoA.
