Biology
1 answer:
Sophie [7]3 years ago
3 0

Answer:

Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.

Explanation:

At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.

Regarding horizontal gene transfer between bacteria by conjugation, transduction, or transformation:
Mice21 [21]

Answer:

Distinct mechanisms are used by bacteria in order to transfer the gene from one bacteria to another. These are transformation, transduction, and conjugation. Transformation refers to the process of uptaking extracellular DNA by the recipient of the other bacterial cell.  

In the process of transduction, the donor DNA gets packed within the bacteriophage and infects the recipient bacteria. In the process of conjugation, the genetic substance is transferred by the donor bacteria to the recipient via the process of mating.  

a. Of all these three mechanisms, transformation is the process that exhibits a broad range and can be easily performed in the lab. As in the process, there is a slight chance of rejection or failure due to direct compatibility between the bacteria.  

b. While the narrowest broad range is found in the process of conjugation, as in order to transfer the genetic substance between the two bacterial species, there should be a similarity between the two species so that they can mate and exchange the genetic substance in between them.

How do ocean currents influence the climate of a place?
sveticcg [70]

<u>ANSWER:</u>

The correct option is A: They transport heat over long distances affecting the wind that blows over the land.

<u>EXPLANATION:</u>

  • Ocean currents carry cool or warm water or currents over long distances thereby affecting the wind that blows over the place bringing about a change in the climate.
  • When the ocean currents carry cool air, the warm wind gets displaced by the cool air and therefore the climate of the place becomes cold.
  • When the ocean currents carry warm air or water, the climate of the place becomes warmer.
  • By transporting hot or cold currents, the ocean currents affect the climatic conditions of land and so bring about a change of weather.
