I’m pretty sure the answer is the third choice
Answer:
The correct answer would be A. nitrate and glucose.
Auxin or Indole-3-acetic acid is a plant hormone which regulates the growth of the plants.
The biosynthesis of the auxin uses tryptophan as the precursor. Tryptophan is first converted to IPA (another amino acid) which is then converted to IAA (Indole-3-acetic acid).
Similarly, the biosynthesis of tryptophan is started from shikimic acid (cyclohexane) or anthranilate (aromatic acid).
Thus, ultimately it requires glucose and nitrogen form the production of auxin.
In addition, the given picture shows that auxin is composed of carbon, hydrogen, nitrogen, and oxygen. All the molecules required for the production of auxin can be provided by glucose and nitrate.
Because by dust blocking the sun, plants would not being able to survive due to lack of food and could no photosynthesize which in turn would provide less oxygen to other organisms and would also decrease the population of herbivores because they would have no plants to eat and this in turn would decrease the amount of food for carnivores. This would essentially starve the population of the earth
Answer:
Snapper population is decreasing
Explanation:
The population is decreasing since the human population is increasing dramatically. As the human population increases, the demand for fish and seafood also increases since humans eat seafood and fish. As the demand for fish increases, fishermen fish for these snappers more often and in bigger loads. Snappers cant reproduce faster than these fishermen are hunting for them and so the population decreases
