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:
yes
Explanation:
The epidermis ( meaning "over-skin") is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment. The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. The epidermis of most leaves shows dorsoventral anatomy
I believe the answer is A.
I ruled out everything but C. and A. so it could be either.
Answer:
Biodiversity is usually defined as the diversification of living species that exist on earth and the complexities that occurs in the ecosystem. It includes all the plants, animals, humans and micro-organisms.
The biodiversity is often affected by factors such as climate change, loss of habitat area, and occurrence of invasive species.
Three of the biological services that are provided by biodiversity are as follows-
- A large number of medicines are being made from the various plant species that exist in an ecosystem.
- It provides food, on which the organisms are dependent on it.
- It also provides materials that are used for construction purpose and used as shelter.
