Describe the main difference between primary and secondary succession.
frosja888 [35]

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.

Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Explanation:

Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.

A Secondary succession can take a few hundred years.

TEA [102]

Answer: shrink

A red blood cell placed in a medium that is hypertonic relative to its cytoplasm will shrink

Explanation:

Since the hypertonic medium has a higher concentration than the red blood cell, water will move out of the cell membrane of the red blood cell into the hypertonic medium.

Thus, after a while the continuous loss of water will cause the red blood cell to shrink (reduce in size)

DaniilM [7]

Answer:

  • Blood sugar regulation in a diabetic patient is done by
  1. Injecting prescribed quantity of hormone insulin after definite time intervals.
  2. Consuming prescribed amount of sugars.
  3. Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.

Explanation:

  • The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
  • When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
  • When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
  • In a diabetic patient, usually the beta cells of the pancreas are affected  but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
  • But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.

Consider the parts of a polar ecosystem and a desert ecosystem.
soldier1979 [14.2K]

Answer:

One biotic factor includes soil, air(oxygen and carbon dioxide), water.

One biotic factor includes animals and plants.
