The right answer is Catabolite repression.

When lactose and glucose are present, the bacteria will metabolize it preferentially: it does not need the enzymes necessary for lactose metabolism. This implies the existence of another regulatory mechanism that is called catabolic repression. It is only when the glucose concentration decreases that the lactose metabolism becomes necessary.

AfilCa [17]

the answer is C) They increase the rate of the chemical reactions involved in digestion

Explanation:

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.

Svet_ta [14]

Answer:

Hypothalamus

Explanation:

The hypothalamus is a part of the brain which possesses temperature receptor cells that detect changes in the man’s temperature, thereby sending signals in the form of electrical nerve impulses to the man’s muscles and nervous system, which in turn respond in counteracting the drop in the normal temperature of the body.  

Once the muscle cells of this man receive these signals, they produce heat through thermogenesis by shivering when the muscle cells begin to contract. This is one of the mechanisms by which thermoregulation is achieved as controlled by the hypothalamus in the brain of the man.
