Answer:

Explanation:

Vaccinations need a large amount of the population to work effectively. With people not getting vaccinated they are putting the majority of the people at risk of an outbreak of that.

How will you determine which strain is wild type and which strain is mutant? Can you justify your answers using molecular biolog
Levart [38]

Answer: The simplest way is to determine if a strain is mutant is observing morphology, growth rate, double time, etc but it is accurate if you can prove if the strain is deficient in one aminoacid or can't metabolize lactose, etc.

Explanation: A wildtype strain functions normally, for example, can metabolize as a carbon source, glucose, lactose and other sugars, can synthesize all the aminoacids requered for protein synthesis, etc. If a strain suffers a mutation and it is inheritable, the strain become a mutant. Since several mutations can be silent ones, only those that interfere with a process, can be assesed easyly.

For example, if you have several strains and put them in a lactose medium, but some of them cannot growth means that are lactose mutants. Those strains could carry a mutation in genes that encode lactose degrading enzymes or in regulatory genes of the lac operon, etc.

Mendel knew that the variations in the offspring generations resulted from his experiments because he
sasho [114]

Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.

Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.

Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

The host range of a virus is determined by A. whether the glycoproteins or capsid proteins on its surface recognize those of the
Marina CMI [18]

Answer:

A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.

Explanation:

Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.

The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.

If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.

What is the single most important factor in determining the temperature of a region?
Vladimir79 [104]
<h2>Answer:</h2>

Geographical location is the single most important factor in determining the temperature of a region.

<h3>Explanation:</h3>

The location of an area and its surrounding environment is most important in its temperature determination. As the area located near to the ocean has a low temperature. And areas which are far away from the waters and there is low precipitation which means low rain. It indicates the higher temperature areas.

Elevation of region, height from the sea level also affects the temperature of region.
