A vaccine is a substance that supports the body to produce antibodies and offer immunity in contradiction of a disease. A live attenuated vaccine comprises a version of the living microbe that has been destabilized because they are still alive this is the closest thing to an actual infection and will habitually lead the body to have a lifelong immunity after only one or two doses. A killed vaccine is created by killing the illness with chemicals, heat or radiation in which these vaccines are harmless but rouse a weaker immune reaction.

andrey2020 [161]

Hello. The chart mentioned in the question above is attached just below.

Answer:

A) has increased with increasing human population

Explanation:

As you can see in the graph below, the line that indicates the number of endangered species increases as the line that represents the increase in the human population increases. This means that the number of extinct species has increased with the increase in the human population.

This is because with the increase in the human population, there is a growing need for natural resources, in addition to increasing the need for cities to expand. All of this results in greater deforestation and extraction of natural resources, which ends up causing an increase in the factors responsible for the extinction of animals.

Which of the following correctly describes Metaphase?
natima [27]

During the metaphase, chromosomes are taken to the equatorial plane, were they randomly line up. Option B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.

<h3>What is the metaphase?</h3>

Metaphase is one of the cell division stages that follows the prophase and precedes the anaphase.

During this phase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes randomly line up.

Once aligned, each chromatid joins with a microtubule of opposites poles and gets ready to go through the anaphase. Sister chromatids are held together until they reach the Anaphase.

Since chromosomes in this stage are well defined and can be observed in detail under the microscope, they are used to create karyotypes and identify chromosomal abnormalities.

These chromosomes have the typical X shape.

Among the options, the one that correctly describes the metaphase is Option is B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
