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.

Homogeneous means one mixture, so like salt water. It looks like one mixture.
Heterogenous means different mixture. Comparable to a bag of Chex mix. So if the magnet can attract the pieces of Iron, it has to be a separable mixture. Compounds would require a chemical reaction to separate.

Why food must be digested before entering your cells?
S_A_V [24]

Answer:

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.     Protein must be broken down into amino acids.     Starches break down into simple sugars.     Fats break down into into fatty acids and glycerol.

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the?
Anvisha [2.4K]

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.

Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.

In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).
