Answer:
The correct answer is C: "The secretory phase of the uterine (menstrual) cycle occurs when <em>progesterone stimulates the endometrium to prepare it for implantation".</em>
Explanation:
The luteal phase, also known as a <u>secretory phase </u>or postovulatory phase, has place immediately <em>after ovulation</em>, from 15th to 28th day, and it lasts <em>until the end of the menstrual cycle</em> when bleeding starts again.
During the secretory phase, the <em>follicle</em> in the ovary <em>produces </em><em>progesterone</em> to keep <em>preparing the uterus for a possible pregnancy</em>. If there is no fecundation, estrogen and progesterone levels fall as the follicle reduces. When this happens, the endometrial is eliminated as menstruation and a new cycle begins.
<em>If the ovule is fecundated, </em><em>it occurs implantation</em><em> </em>and follicles continue to produce progesterone and estrogen in high amounts to sustain the endometrial until the placenta is formed.
Answer:
Yes, with the assistance of electroporation the bacteria Enterococcus can be made competent, and afterward, the Streptococcus bacterial genes can be presented within the Enterococcus with the help of a cloning vector.
The electropermeabilization or electroporation refers to a microbiology technique in which the permeability of the cell membrane is enhanced with the application of the electric field. This permits drugs, chemicals, or DNA to get presented within the cell.
The procedure of electroporation is generally used in the field of microbiology to transform yeast, bacteria, or protoplasts of plants by presenting novel coding DNA.

Explanation:
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.
When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.
If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.
