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.
Answer:
The independent variable is the projection of yhe light rays, and the dependent variable is the refraction and bending
Answer: Summer
Explanation: When the southern hemisphere is closest to the sun, and it receives the most sunlight it is summer time, while in the northern hemisphere it's winter.
The main factor that determines seasons is the way sun rays enter Earth, and not as much proximity, since there is only a 2% variation in the distance overall
1. The cells divide by constriction of a protein, it is true in case of Bacteria and Animals, and false in case of Plants.
2. The presence of a cell wall inhibits the cell from differentiating by constriction, it is false in case of bacteria; though bacteria exhibit a cell wall but still divide by constriction. It is also false in case of animals, but true in case of plants.
3. Tubulin-like molecules or tubulin subunits function in the division of the cell. The statement in true in case of bacteria and plants, but is false in case of animals.
