A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm. What can the researcher conclude about the cells?

Answers

Answer:

A is a eukaryotic cell while B is a prokaryotic cell

Explanation:

The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.

In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.

Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.

What would happen if a mutation created a new allele that decreased fitness?

Answers

Fitness describes a reproductive success of an individual. For example, there are green and yellow beetles in a population. If a color affects the reproductive success, for example, green beetles will have more offspring that the brown ones because of their color. So, green beetles have higher fitness. And the beetles with decreased fitness will have less offspring.

So, if a mutation creates a new allele which decreases the fitness, the altered allele will not be inherited in such a ratio as the unaltered allele will.

Root hairs absorb nutrients from soil against the nutrient concentration gradient. to achieve this, root hairs use _____.

Answers

Root hairs absorb nutrients from soil against the nutrient concentration gradient. To achieve this, root hairs use - proton pumps.  

Root hairs are long tube shape outgrowths from root epidermal cells. These are also called absorbent cells as they absorb water and nutrients from the soil.

  • Nutrients are absorbed by the root hairs by a proton pump.
  • This proton pump builds up a proton gradient across a biological membrane.
  • Proton pumps catalyze the following reaction: H+ + energy ⇌ H +

Thus, Root hairsabsorbnutrients from soil against the nutrient concentration gradient. To achieve this, root hairs use - proton pumps.
