In this exercise, you will compare the amino acid sequence from the aphid to the amino acid sequences of the other species to id

entify how similar they are. As a first step, you will compare the aphid sequence (Acyrthosiphon) to a bacterial sequence (Pantoea).
The sequences below show the first 60 amino acids of one polypeptide, using the one-letter abbreviations for the amino acids. An underscore (_) indicates a gap inserted in a sequence to optimize its alignment with the corresponding sequence in Arabidopsis.

Which of the following have been linked to the dramatic global decline of amphibian populations? Select one: a. drainage of wetl
charle [14.2K]
<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.
