Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

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.
