A 6-month-old girl is taken to emergency department in January suffering from profuse watery diarrhea and vomiting. She has had

a low-grade fever for 48 hours and appears to be dehydrated. The suspected cause of the diarrhea is an icosahedral virus that has a double capsid and a double-stranded RNA genome. 1. Which is your diagnosis in this case

My diagnosis in this case is that the 6-month-old girl suffered from the infection caused by the virus called rotavirus.

<h3>What is rotavirus?</h3>

A rotavirus belongs to the genus within the family of virus called Reoviridae. They are made up of a double capsid and a double-stranded RNA genome.

The symptoms of this virus include:

  • watery diarrhea,

  • nausea and vomiting,

  • low-grade fever.

Therefore, the correct diagnosis should be that the 6-month-old girl suffered from the infection caused by the virus called rotavirus.

Assume that the mutation rate for a given gene is 1 × 10−6 mutations per generation. For that gene, how many mutations would be
sertanlavr [38]

Answer:

500

Explanation:

Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time

So given that;

the  mutation rate of a particular gene = 1 × 10⁻⁶

The expected mutations after 500 million sperm are examined will be:

= (1 × 10⁻⁶)×(500,000,000)

= 500

Thus, The expected mutations  = 500

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
stiv31 [10]

Answer:

On the exterior of the cell.

Explanation:

The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.  

In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.  

After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.

Explain the stages of tissue repair and fill in the blanks.
svp [43]

Answer:

a. Following an injury that breaks the surface of the skin. blood vessels dilate as a result of histamine release from mast cells and other damaged cells.

b. The blood forms a clot and upon drying, a scab forms a barriers between the body and the environment, while phagocytes work to clear the underlying debris from the wound site.

c. Blood vessels begin to re-grow into the wound while fibroblasts begin process of replacing the blood clot with Collagen

d. The remodeling phase then occurs as fibrosis and regeneration of tissues may continue for prolonged period of time.

Explanation:

Hello. Although you did not have all the answer options for the blanks presented in the sentences above, it is possible to conclude that the words in bold are the most appropriate to fill these spaces.

That's because when we cut ourselves, the blood vessels on the surface of our skin rapidly dilate, allowing a flow of blood to be observed. This dilation is accomplished by the release of histamine, which is released by mast cells, which are glands that regulate the immune response. At this point, it is important that any impuzera or microorganism, close to the wound site, is removed and this site undergoes cleaning. This is done by phagocytes, which are intended to prevent the cut from becoming the entrance to a bacterial infection.

Then the blood vessels begin to move and grow again across the wound, with the aim of covering this opening. In this comment, fibroblasts begin to apply collagen and replace the blood clot formed to prevent blood loss. Collagen will be responsible for maintaining the skin and tissues that will be rebuilt in the remodeling phase.
