I don't think one process can go on continuously without the other. Because during the photosynthesis carbon dioxide is necessary along with sunlight, water to make glucose and oxygen. Without oxygen we won't survive if we don't survive then there will be no carbon dioxide. Aerobic respiration is when you take in oxygen made by plants in the process of photosynthesis as the product of aerobic respiration we breath out carbon dioxide which plants use to make glucose and oxygen.
(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts
Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
Antibodies protect our bodies from the invasion of foreign particles (pathogens)
Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
An adaptive immunity can remember the antigen because it produces memory cells
