Answer:

Gram positive and Gram negative

Explanation:

Bacteria are classified as gram positive or negative depending on whether or not they take up gram stain. The bacteria cell wall is unusual in its chemical construction .It has a strong layer of sugar polymer, cross-linked by amino acid and called *PEPTIDOGLYCAN*.

The bacteria cell wall that has a much of peptidoglycan stains *blue, and termed Gram positive*,while the *gram negative have less peptidoglycan and stained pink to red*. Example of Gram positive bacteria are Clostridium tetani, wound infecting Staphylococcus aureus(spherical),Tuberculosis-causing actinomycetes -Mycobacterium tuberculosis. Examples of Gram negative bacteria are Syphilis causing Treponema pallidum(spiral),Escherichia coli(rod), gonorrhea causing Neisseria gonorrhoeae(spherical),and Cyanobacteria.

The mammary glands enlargement during pregnancy primarily as a consequence of what hormonal process?

Masteriza [31]

Answer:

c-hormonal hyperplasia

Explanation:

When there is increase in the number of cells and tissues that appear normal under the microscope,Hyperplasia is said to occur.If these occur in cells of an endocrine gland of a system,then it is refers to as hormonal hyperplasia.

Therefore during pregnancy,the proliferation of the glandular epithelium in a pregnant woman (and at puberty in a females are examples of hormonal hyperlasia.

Its possible causes are;

a surge in local production s of growth factors,

In the numbers of growth factors receptors on the cells receptive to the factors,

and due to activation of specific intrancellular signalling pathways.

Two insect groups vary genetically by two genes. When put together,they were able to reproduce and produce offspring that could

nikitadnepr [17]

<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

KonstantinChe [14]

True

DNA are cells that carry genetic codes and are passed down through generations of offspring. New cells can only arise from existing cells!
