Answer:
C. Plants produce chemicals to deter herbivores. Bitter cassava stores toxic compounds in its tissues. Bitter cassava should incur less damage, and therefore have higher yields.
Explanation:
Bitter cassava are able to produce higher yield because they are less disturbed by herbivores due to the production of herbivore-deterring chemicals in their tissues, especially the tissues that are above the ground.
Sweet cassava that is not able to produce the herbivores-deterring chemicals incur damages to its tissues. These damages affect the physiological functions of the plant and thus leads to reduced yield.
<em>Options A is incorrect because herbivores can only get to above the ground tissues.</em>
<em>Option B and D are factually incorrect.</em>
The correct option is C.
Temperature control is another negative feedback mechanism. ... This example is very complex because the hypothalamus can change the body's temperature set point, such as raising it during a fever to help fight an infection. Both internal and external events can induce negative feedback mechanisms.
The cells in the small intestinal mucosa that secrete mucus are the Goblet cells. These cells are also found in other parts of the body such as the bronchi, trachea, larger bronchioles, large intestines and the conjuctiva in the upper eyelid where they are responsible for secreting mucin in tears. In the small intestine mucosa they secrete mucus that ease the movement of feces and also protects the intestine from the corrosion by acids and gases produced by enteric bacteria.
