Answer:
B.) Duplication
Explanation:
A.) is incorrect because deletions involve the removal of one (or more) nucleotides during the DNA replication process.
B.) is correct because duplication involves duplicating a nucleotide (or more) of the DNA strand. This results in repeated genetic material.
C.) is incorrect because inversion involves a section of DNA bein removed and reattached backwards during DNA replication.
D.) is incorrect because translocation involves a section of a chromosome being removed and added to another chromosome.
Answer: 2. the production of new body cells to replace old cells
<span>Mitosis is a form of cell division that results in two daughter cells that are identical (genetically) to each other and to its original cell. It plays a vital role in the life cycle of most living things. </span>
<span>In single-celled (unicellular) organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell.</span>
<span>In multicellular organisms, mitosis produces new cells to replace old cells and promote growth and repair. </span>
To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.
Answer:
The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species' young.
