Which best illustrates a result of natural selection?
Yanka [14]

Answer: The correct answer is -

D) giraffes having increasingly longer necks over time.

Natural selection is an evolutionary mechanism that was proposed by Darwin.

According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.

Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).

This is considered as a peculiar example of natural selection.

Answer:

1. when there is cardiovascular disease.

2. High blood pressure increases the likelihood of suffering a stroke, a heart attack, heart failure, kidney disease or premature death.

3. The mitral valve opens.

Explanation:

1. High blood pressure is a common condition in which the force exerted by blood against the walls of the arteries over the course of time is high enough to cause you health problems such as heart disease. After the first rise of pressure caused cardiac ejection volume, one notch occurs with a second ascent product of the reflection of the pulse wave. In younger individuals, with elastic arteries, said wave occurs in diastole, so does not influence the peak systolic pressure. By contrast, with advancing age and the stiffness of large vessels, the reflected wave is transmitted prior to the aorta (systole) so as to increase the peak central PAS.

2. The pressure increases progressively the pressure of the blood flowing through the arteries. As a result, you can submit the following: Arteries damaged and narrowed. High blood pressure can damage the cells of the inner lining of the arteries.

3. When the pressure in the left ventricle falls below the pressure of the left atrium, the mitral valve opens, and the left ventricle fills with blood that had been accumulating in the left atrium.
