Answer:

Plasmids

Explanation:

A plasmid is an extra chromosomal DNA. These are small sized double stranded circular DNA. It is generally present in the bacterial cells. Plasmids are present in bacteria and some eukaryotic cells. During bacterial cell division, the plasmid is also copied and moves to the daughter cells. During bacterial conjugation, plasmids get transferred from one bacterium to another bacterium. Plasmids are used as vector by the scientists during manipulation of genes.

Some viruses can undergo lysis or lysogeny within the same host. Under what conditions might the virus favor lysis instead of ly

bezimeni [28]

<h3>Under this conditions virus might favor lysis instead of lysogeny:</h3>

- according to the state of the host cell (can switch)

- in a healthy host, the virus can multiply and create new virions.

- unhealthy host: Lack of energy permits the lysogen to incorporate DNA into the host cell, where it can wait for the cell's health to improve.

<h3>What is lysis?</h3>

A common result of viral infection is cell lysis. Cellular membranes are damaged, which causes cell death and the release of cytoplasmic substances into the extracellular environment.

<h3>What is lysogeny?</h3>

One of two viral reproduction cycles is lysogeny, sometimes known as the lysogenic cycle. The bacteriophage nucleic acid is integrated into the host bacterium's genome during lysogeny, or a circular replicon forms in the bacterial cytoplasm.

a client is diagnosed with an st segment elevation myocardial infarction (stemi) and is receiving a tissue plasminogen activator

SVETLANKA909090 [29]

A client is diagnosed with an st segment elevation myocardial infarction (stemi) and is receiving a tissue plasminogen activator, alteplase. monitoring for signs of bleeding is the priority nursing intervention.

<h3>Tissue Plasminogen activator:</h3>

It is a thrombolytic. symptomatic and systemic hemorrhage is a complication of any type of thrombolytic medication.

Tissue Plasminogen activator is an enzyme which is useful to treat diseases which includes heart attack, strokes and blood clots ,etc.

It is one type of glyco-protien which produced mainly a vascular endothelial cells.

The side effects of tissue Plasminogen activator includes headache, bleeding from the wound, paralysis, difficulties in breathing and swallowing, etc.

Alteplase is a fibrinolytic agent . it is also referred to as tissue plasminogen activator (tPA). Alteplase converts plasminogen to the proteolytic enzyme plasmin, which lyses fibrin as well as fibrinogen.

<h3>What is blood clots? </h3>

Blood clots are gel-like thick collections of blood that form in your veins or arteries when blood changes from liquid to partially solid.

A blood clot is also called a thrombus.

Bumek [7]

Answer:

The correct option is: a. PIH

Explanation:

The PRH or the prolactin-releasing hormone is the hormone responsible for stimulating the release of prolactin from the anterior pituitary gland. Prolactin then stimulates the mammary glands of the mammals, usually females, to produce milk.

The PIH or the prolactin-inhibiting hormone, also known as dopamine, inhibits the production of prolactin and thus blocks the milk formation in males and non-pregnant females.
