The correct answers are ATMOSPHERE and BIOSPHERE. Nitrogen is most abundant in the ATMOSPHERE, but nitrogen can't be absorbed by the BIOSPHERE without the help of a special bacteria and without undergoing a process called nitrogen fixation.
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
Answer;
-Disruptive selection
Disruptive selection results in the creation of two distinct phenotypes.
Explanation;
-Disruptive selection is a type of natural selection that selects against the average individual in a population. The make up of this type of population would show phenotypes of both extremes but have very few individuals in the middle.
-The variance of the trait increases and the population is divided into two distinct groups. The disruptive selection will cause organisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more.
Answer:
A and D
Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.
If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:
- Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
- The normal synthetase might be present but not in an adequate amount.
