Integrase is the viral enzyme that catalyzes the Integration of virally derived DNA into the host cell DNA in the nucleus, forming a provirus that can be activated to produce viral proteins.
Answer:
D. Decreasing vessel diameter
Explanation:
Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.
Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.
The primary step is to train the health care professionals about the injection techniques and to determine if the child is of the appropriate age to receive the injection.
Good injection practice deals with selecting the appropriate site for administration. The route of administration of injection is mostly intramuscular in a child. The drug is delivered to the vascular muscle tissue and is rapidly absorbed into the circulation of the child. Diabetes insipidus is a disorder that leads to imbalanced fluid in the body. This causes frequent urination, a condition referred to as polyuria. Vasopressin is the anti-diuretic hormone, the lack of which causes diabetes insipidus. Administration of vasopressin externally helps the kidneys to retain water and prevent dehydration.

Answer:
It neutralizes the virus
Explanation:
When a vertebrate is infected with a virus, antibodies are produced against many epitopes on multiple virus proteins. A subset of these antibodies can block virus infection by a process that is called neutralization.
Antibodies can neutralize viral infectivity in a number of ways, as summarized in the illustration. They may interfere with virion binding to receptors, block uptake into cells, prevent uncoating of the genomes in endosomes, or cause aggregation of virus particles. Many enveloped viruses are lysed when antiviral antibodies and serum complement disrupt membranes.

Answer:
The answer is C. FSH
Explanation:
The development of the follicle in the ovary is caused by the increase in blood levels of the follicle stimulating hormone (FSH). FSH is responsible for regulating the follicular phase of ovulation. It is synthesized and secreted by gonadotropic cells of the anterior part of the pituitary gland. FSH stimulates the production of oocytes and a hormone called estradiol during the first half of the menstrual cycle.
