<h2>The correct answer is: e.</h2>

Explanation:

  • Decline in the global population of amphibians is due to multiple reasons which include:
  1. A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
  2. Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
  3. Infectious diseases often cause their death resulting their population to decline.
  4. Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.

Which region of the human alimentary tract has both the largest population of bacteria and the greatest species diversity
n200080 [17]

The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

<h3>The normal flora of the alimentary tract</h3>

Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.

These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.

From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.

The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.

Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

prisoha [69]

Answer:

Capsule

Explanation:

In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.

The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.

In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.

Thus, the capsule is correct.

Distinguish between breathing and respiration.​
Roman55 [17]

As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
