Answer:
Absolutely not mitosis and meiosis don't stop until your heart stops beating.
It is false that When you stop growing, your cells stop dividing.
When you stop growing, it does not mean that all your cells stop dividing. In fact, cells in the human body continue to divide and replenish throughout life, albeit at different rates depending on the type of cell.
The human body is composed of various cell types that have different lifespans and rates of cell division. For example, cells in the skin, gastrointestinal lining, and blood undergo continuous division and turnover to replace old or damaged cells. These tissues are constantly renewing themselves.
However, some cells, such as neurons in the brain and muscle cells, have limited or no capacity for cell division after a certain stage of development. These cells primarily grow in size rather than dividing to create new cells. Therefore, not all cells in the body continue to divide once growth stops.

They lower the activation energy of the reaction
They increase the number of available reactant particles
They absorb energy from the products
They provide energy to the reactants
Answer:
They lower the activation energy of the reaction
Explanation:
Enzymes are proteinous biochemical molecules that serve as catalyst in living systems. They speed up the rate of biochemical reactions by lowering the activation energy of the reaction they are involved in.
As this question describes, enzymes possess an active site, which the substrate binds to yield products. The enzymes make the reaction faster by reducing the activation energy of the reaction, which is the energy needed to start a reaction.

List the following structures from largest to smallest: proton pump, nuclear pore, cyt c ribosome,
nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

Answer:
Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Anton van Leeuwenhoek was the first person to see protozoa, using microscopes he constructed with simple lenses. Between 1674 and 1716, he described, in addition to free-living protozoa, several parasitic species from animals, and Giardia lamblia from his own stools.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins
Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.
Indicate which the following statements are true.
a. During glycolysis, glucose molecules are hydrolysed to yield CO2 and H2O
b. The cleavage of fructose 1,6-bisphosphate by phosphofructokinase yields two molecules of glyceraldehyde 3-phosphate.
c. When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.
d. In the mitochondrial matrix, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH.
e. Fatty acids can be transported into mitochondria and converted into acetyl-CoA, FADH2 and NADH
Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.

C. total mass
D. total energy
Answer:
I think it's chemical bonds I'm not of that helped
The changes occurs in chemical bond during a chemical reaction between two compounds. The correct option is B.
What is chemical bond?A chemical bond is a long-lasting point of attraction among atoms, ions, or molecules which then allows chemical compounds to form.
Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.
A covalent bond is the strongest bond in chemistry. In such bonding, each atom shares electrons that bind them together.
The bonds that hold molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.
Each bond requires a different amount of energy to break or form; without this energy, the reaction cannot occur, and the reactants remain unchanged.
Thus, the correct option is B.

The diffusion of water molecules a secectively permeable membrane.
What is Diffusion?The net passive movement of molecules or particles from areas of higher concentration to areas of lower concentration is known as diffusion. There needs to be a concentration gradient for diffusion to happen.
The dissimilarity in the quantity of solutes, particles, or molecules between the two locations will drive them to travel between the two regions.
The gradient created by the uneven particle concentration between two fluids will cause the particles to move in order to balance the discrepancy in concentrations. However, solutes do not migrate in a single direction during the diffusion process.
Therefore, The diffusion of water molecules a selectively permeable membrane.
