why is that cell structure and function are related because
Answer:
You should know, the cell is our most essential body forming unit. Each organ in our body is all formed of cells. Cells divide and multiply in order to make new organs as well as gametes. The cell is known as the structural and functional unit of life because all living beings are formed of cells.
Fruit flies have 8 chromosomes. During mitosis, one cell with 8 chromosomes divides to form 2 cells each with 8 chromosomes, how is this possible?
Owing to the fact that the parent cell duplicates itself with the same number of chromosomes into the daughter cells then the daughter cell each have eight chromosomes.
What is cell division?The term cell division has to do with the process by which a cell is broken down to give daughter cells. The process of cell division is responsible for the growth of the organisms. There are two kinds of cell division and these are the mitosis and the meiosis.
While mitosis occurs in the body cells, meiosis occurs in the gamete cells of the organisms. We know that in mitosis, the cell duplicates the exact same number of chromosomes in the parent nucleus into the daughter nucleus hence the daughter nuclei both have eight chromosomes.

Glycolysis=___NADH x____=____ATP
Glycolysis = 2 NADH × 3 = 6 ATP.
The process by which glucose is broken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell. Both aerobic and anaerobic creatures experience it.
The sugar (glyceraldehyde-3-phosphate) is oxidized in the sixth step of glycolysis, which releases high-energy electrons that are then taken up by the electron carrier NAD+ to create NADH. A second phosphate group is subsequently added to the sugar, phosphorylating it and creating 1,3-bisphosphoglycerate.
And we know that 1 NADH molecule equals to 3 molecules of ATP. thus 2 molecules of NADH will produce total 6 molecules of ATP.

True story! In some lakes and reservoirs, anglers fish a lot for bass. The fish in these lakes are said to be "heavily pressured."Bass that get caught may be kept for food or trophies, or even if they are released, they may be stressed or injured by the experience. Sometimes males that get caught will abandon their nests, which often causes their eggs or offspring to be eaten.The chance that a bass will get caught is partly a result of genetically based personality differences among the fish: "bold" fish are curious and bite almost anything that moves, including fishing lures. "Shy" fish are much less likely to investigate or bite strange objects.Which personality is favored by heavy fishing?Group of answer choicesThe bold, aggressive personality type works better under heavy fishing pressure. These fish will take over in a "heavily pressured" lake and will become the norm.The shy personality type works better under heavy fishing pressure. Over time the bass in a "heavily pressured" lake will tend to become more shy and harder to catch.The personality of a fish doesn't affect its survival. There is no selection at work in this example.
We must remember that many conditions work together to exert a selective pressure and not only a single trait determines this, nonetheless, in the present example, but we can also see that those that are bold easily can bite the bait, so makes them vulnerable to fishing even if they support better stress, meanwhile those shy are more elusive and even if they do no deal well with stress are harder to catch and more careful so, the best answer is the second option.
Which of the following statements correctly describe(s) the relationship between the classes of hormones and their behavior or function?
The general chemical nature of a hormone can be used to predict: how soluble the hormone is in water. whether the hormone will be able to move through the cell membrane. whether the hormone interacts with receptors on the cell membrane. whether the hormone interacts with receptors inside the cell. whether the hormone will increase or decrease a specific cell function.
The correct options are:
How soluble the hormone is in waterwhether the hormone will be able to move through the cell membranewhether the hormone interacts with receptors on the cell membranewhether the hormone interacts with receptors inside the cellLet us understand these points in brief.
1) How soluble the hormone is in water. It depends on whether it is hydrophilic or hydrophobic. Example, the hormones deprived of lipids are hydrophobic, like, steroids. It means they are insoluble in water. Since, they are insoluble in water, so, they can be used to transport proteins.
2) whether the hormone will be able to move through the cell membrane. Hydrophilic hormones (from amino acids) are unable to diffuse through the lipid bilayer. So, the hormones which are derived from lipids are able to pass through the membrane because they are able to diffuse through the lipid bilayer. This diffusion occur through the membranes that have internal receptors.
3) whether the hormone interacts with receptors on the cell membrane. Since hormones are chemical messengers so they are able to interact with receptors that are present on the surface of the cell. That is how they effect the target cells.
4) whether the hormone interacts with receptors inside the cell. There are few receptors present inside the cells too. These hormones have the ability to interact with the receptors present inside the cells.

A->B->C->D->E
a. spontaneous
b. endergonic
c. it cannot be determined from the information given
d. exergonic
Based on the information given, the reaction C->D is endergonic.
What are endergonic reactions?Endergonic reactions are chemical reactions that are driven by energy. In other words, they are reactions that consume energy in order to take place. This energy is usually in the form of heat.
Endergonic reactions are unique from exergonic reactions. The latter does not consume energy in order to take place, rather they release energy. Similar to endergonic reactions, the energy is also usually released in the form of heat.
The reaction: ATP -> ADP is known as ATP hydrolysis. When it happens, the energy in one of the phosphate groups in ATP is released. This energy is utilized to drive reactions that require energy.
Thus, if C->D requires that an ATP molecule is hydrolyzed, it means the reaction requires energy. The energy released from the hydrolysis of ATP is what is used to drive the reaction.
Thus, C->D is an endergonic reaction.
