The type of digestion that involves the actual breaking apart and chewing of food is called MECHANICAL DIGESTION. Mechanical digestion increases the surface areas of the food which makes the food easier to digest. Examples of mechanical digestion are mastication and peristalsis.

Advantages of constant body temperaure
Leya [2.2K]
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life. 

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm. 

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size. 

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.

Explain why cold-blooded organisms like reptiles have a higher rate of secondary productivity than warm-blooded mammals.
PIT_PIT [208]
Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.

The term respiration describes the exchange of gases between your blood and the air. Cellular respiration ________.
kotegsom [21]

Answer:

The term describes cellular respiration

Explanation:

Cellular respiration, also known as internal or tissue respiration can be represented by the equation:

C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)

From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
