Distinguish between systolic and diastolic blood pressure
BartSMP [9]

Answer:

Blood pressure is usually defined as the pressure exerted by the blood that circulates on the walls of blood vessels. This pressure is created when the heart pumps blood continuously throughout the circulatory system.

The blood pressure have two numbers, one at the top and one at the bottom. The number showing at the top shows the amount of pressure exerted on the arteries when the muscles associated with the heart gets contracted. This is commonly considered as the systolic pressure. On the other hand, the number at the bottom shows the amount of pressure that is exerted by the heart muscles between the heart beats and this is known as the diastolic pressure.

The systolic blood pressure is more important compared to the diastolic blood pressure because it enables the person who measures the blood pressure or a doctor, to determine the risk of having a heart attack.

Art [367]

Evolutionary game theory is a mathematical modeling approach to predicting the outcome of natural selection on behaviours when multiple organisms are interacting.

<h3>What is natural selection? </h3>

According to modern concept of evolution natural selection is not a bloody battle as was emphasized by Darwin and Wallace.

It is a peaceful process that has little to do with, "struggle for existence" or "elimination of unfit" or "survival of the fittest".

Natural selection really means differential reproduction ( some members of the population produce lage no of offspring, some are few and still others none.

Those that produce large no of offspring contribute greater percentage of genes to the gene pool of the next generation than those that produce fewer offspring.

If differential reproduction continues for many generation ,then genes of the individual which produce more offspring will become predominant in the gene pool of the population.

This leads to change in the gene frequency of the population.

Individual which are best adopted to the environment having greater no of surviving ones.

Survival of the organism to the reproductive age and their selection for mating is the important factors which results in differential reproduction.

There are three types of natural selection stabilizing

selection, directional selection and disruptive selection.

A malaria outbreak causing a Lily's frequencies to change is an example of
Dima020 [189]

Answer:

A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>

Explanation:

Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.

When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
