Which 3 of the following are examples of feedback mechanisms which helps maintain homeostasis?
kari74 [83]

Answer: The correct answer is-

C. Insulin secretion in response to high blood sugar.

D. Increased heart rate in response to exercise.

F. Proton pumping to maintain a proper pH level.

Homeostasis can be described as a tendency of living organisms to maintain a state of stable internal environment. In other words, it is the tendency to resist any change in the optimal conditions for survival.

It is brought by several regulatory mechanisms in the body such as regulation of body temperature, regulation of pH, regulation of osmolarity etc.

  • Whenever there is high blood sugar level, insulin hormone is secreted from pancreas that reduces the blood sugar level.
  • Heart rate is increased in response to exercise so that more oxygen is transported through blood circulation and more amount of energy is harvested through cellular respiration in the form of ATP ( required in exercise).
  • Pumping of proton maintains a proper pH level ( such as in lysosomes, where pH is highly acidic, high proton concentration is regulated through proton pumping).

Thus, option C), D), and F) are the examples of feedback mechanisms  that help in maintaining homeostasis.

1,000,000 bacteria living in a 5cm^2 (squared)
valina [46]

Answer:

Bacteria grows very fast.

Explanation:

There are 1,000,000 bacteria living in a 5 centimeter square means that each centimeter square has 200,000 of bacteria. This figure shows that the bacteria grows rapidly and having very large population in a very little space due to its smaller size. It grows in colonial form and have a very short life cycle. It reproduce through asexual reproduction which is binary fission in which one bacterial cell divides into two cells.

What is the inducer molecule in the lac operon?
Sunny_sXe [5.5K]

Answer:

Allolactose

Explanation:

  • <u>The inducer in the lac operon is allolactose. Allolactose is the inducer of lac operon since it turns on, or induces the expression of the lac genes. </u>
  • In the presence of lactose in the medium, some amount of lactose will be converted to allolactose by the enzymes β-galactosidase present in the cell.
  • Consequently Allolactose binds to the repressor molecule, hence reducing the repressor's affinity for the operator site.
