Which of the following best describes what happens to an enzyme after it catalyzes a chemical reaction? (2 points) It is unchanged and can be used again for the same chemical reaction. Its mass decreases since part of the molecule is used up. Its shape changes, giving it different chemical and physical properties. It becomes chemically bonded to the products of the reaction.

What is the second great discovery of genetics?

Answers

Answer:

Genes on chromosomes

Explanation:

It has been conclusively established that chromosomes contain the hereditary material or factors that are transmitted from parent to offspring. These factors are called genes. A gene is a short portion of a DNA molecule and is chemical in nature. A gene codes for a specific protein by specifying the order in which the amino acids are linked together.

How many genotypes are possible for the offspring? Explain.

Answers

Usually when you are trying to figure out different possibilities of offspring using punnet squares, 4 genotypes can be figured out. I think that it also depends on how you are finding out the different genotypes for offspring.

The process in which an animal’s cells use oxygen and digested food molecules to release the energy in food is calleda. Breathing
b. cellular respiration
c. diffusion
d. gas exchange

Answers

Answer:

The correct answer would be b. cellular respiration.

Cellular respiration is defined as the set of metabolic reactions taking place in a cell in order to harness energy from food and convert it in the form of ATP (adenosine triphosphate).

It includes glycolysis, pyruvate decarboxylation, Krebs cycle, and oxidative phosphorylation (electron transport chain, and chemiosmosis).

It requires oxygen for complete oxidation of food (glucose) in order to produce ATP and release carbon dioxide as a byproduct.

The overall reaction can be written as:

C₆H₁₂O₆ + 6O₂  → 6CO₂ + 6H₂O + energy (ATP)
B because for example, living things breathe, but it goes through a process. And that's cellular respiration.
