what species of organism does the gene donor cell belong to?

Answers

Answer:

Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing into two daughter cells. The daughter cells that result from this division are genetically identical to each other and to the original parent cell. Thus, over time, asexual reproduction in bacteria can lead to a population of hundreds of thousands of cells, all of which are genetically identical to a lone original parent cell.

Given their asexual method of reproduction, it is tempting to think that bacteria are sorely lacking in genetic variation, but this is not the case. Prokaryotic cells have developed a number of methods for recombining their genetic material, which, in turn, contributes to their genetic diversity. The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. However, not all types of bacterial cells are capable of engaging in all three processes.

What is the measurement of the velocity of moving particles the Doppler effect is based

Answers

The Doppler effect is the phenomenon whereby a monochromatic wave reflected by a moving target undergoes a frequency shift which is proportional to the target velocity, namely ω = ωo(1 − v · n/c), where v is the target velocity, c is the wave velocity and n is the unit vector in the direction of the reflected ray.

plz help

Answers

Answer:

Hello! Sorry I am late! Here is my best answer below!

Temperature depends on the tilt of earth. The closer the earth is to the sun the warmer it gets. If the sun is not pointing at the place you live in the earth the temperature where you are will be colder. If the sun is pointing at the place you are the temperature will be warm. In conclusion, the temperature just depends on the tilt of earth towards or away from the sun.

Some more information:

At night you may discover that it is much colder than during the day. This is because the sun is not pointing at that half of the earth.
