#4 A person sweating on a hot day would most likely be an example of what biological process?
A) digestion
B) respiration
C) homeostasis
D) Gametogenesis
I think #4 is digestion

Answer 1

Number 3 is b number 2 iis A  sure and ther rest I am not very sure about yet.

Answer 2

1: Released

2. Cellular respiration

3. B) The enzyme fits tightly with the substrate

4. C) Homeostasis

Step-by-step explanation:

1. During exergonic reactions, the energy is released into the surroundings. This occurs since the energy levels of the product/s are lesser than that of the substrates. Therefore, the extra energy is released in the form of heat or is used to drive an endergonic reaction.

2. Cellular respiration is the process by which nutrients are completely oxidized into CO2 and H2O in the presence of oxygen. The energy released during oxidation is used to form ATPs. Cellular respiration includes glycolysis, Kreb's cycle, and oxidative phosphorylation.

3. Enzymes have specific binding sites for substrates. These binding sites are called active sites. Substrates bind tightly to the active site of the enzyme to facilitate the enzymatic action.

4. Homeostasis is the process of maintaining the constant internal environment of the body. During hot summer days, the temperature of the body is increased. To counteract the increase in body temperature, sweat glands of skin secrete and release sweat. Evaporation of sweat from the skin surface leaves the cooler surface behind and thereby helps in lowering down the body temperature.
