Answer:
The life cycle stage of an animal virus during which a mature capsid forms around copies of the viral rna genome is called <u>excision.</u>
Explanation:
Animal viruses need to infect a host in order to achieve their reproduction and subsequent survival. When the process of producing new phages occurs, they need to leave the host cell and infect other cells. This situation occurs because a process called excision is carried out. In this process, what happens is that the genetic material, in this case the RNA, is packaged in a wrap called a capsid and thus can leave the cell with a protective barrier that will allow it to infect a new host.
Answer:
The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.
Explanation:
In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.
Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.
In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).
Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

<span>An incorrect number of
chromosomes is the most common form of genetic disorder that causes the fetus
to spontaneously abort. </span>The
human cells normally contain 23 pairs of chromosomes, for a total of 46
chromosomes in each cell. Error in one or more of the meiosis, mitosis,
maternal age, or environment are the possible cause of the chromosome
abnormalities. These abnormalities in the number chromosomes can cause problems
with development, growth and function of the body's systems. These changes can
occur in early fetal development, or in any cell after birth during the
formation of reproductive cells (sperm and eggs).
