Many scientists believe horizontal gene transfer (HGT) is a significant source of genetic variation. Why
lawyer [7]

In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.

Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili

explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your mic
Kazeer [188]

Answer:

Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;

1. Always carry the microscope with two hands

2. Do not touch the microscope lens

3. Clean and store properly after using

Explanation:

1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.

2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.

3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.
