At a minimum, primary producers require water, carbon dioxide, and light. These are things that are readily available in most ecosystems. However, we do not observe the same rates of net primary productivity in every region of the globe. Which of the following statements BEST reflects one reason why rates of productivity are not the same everywhere?
A.) Rates of net primary productivity are actually the same everywhere; scientists just need to calculate the rates relative to plant biomass in a given ecosystem.
B.) Although water is limited in certain ecosystems, nutrients that are scarce actually limit net primary productivity because they are necessary for growth.
C.) Rates of net primary productivity are actually limited by the amount of solar radiation. If net primary productivity were calculated as a yearly average, then this would show that ecosystems have the same rate of productivity.
D.) Although water is limited in certain ecosystems, irrigation would solve the problem and equalize rates of net primary productivity in every ecosystem.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source.i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
