Answer:
A. carbon dioxide- has the greatest effect on climate
Answer:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.
Explanation:
- Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
- Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
- Natural selection is the machine that drives evolution. It also explains adaptation.
Answer: Diffusion occurs due to the random movement of particles. It usually happens due to a concentration gradient, meaning that molecules move from an area of high concentration to an area of lower concentration.
Explanation:
The genetic info is found in the nucleus.
