Which of the following statements is not true about the digestive system and its contribution to homeostasis? a. the digestive system to maintain the correct amounts of nutrients for the body tissues to do its job. b. the digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. c. the digestive system breaks down food sources into the needed nutrients and deposits these nutrients into the blood for use by the cells. d. all of the above

Answer;

B. The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues.

Explanations;

Homeostasis involves the maintenance of a constant body environment.

The digestive system is not responsible for monitoring the amounts of oxygen and carbon dioxide in the blood and tissues. (It is the function of the breathing system together with the circulatory system).

Digestive system instead helps maintain homeostasis in a number of ways, For instance;

-By changing the pH from the saliva for example, which makes the gastric environment acidic which helps the break down of food readily and fast and also protect the body from bacteria.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
