Answer:
Wildfire
Explanation:
The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire. It manages to burn down very large areas of grasslands or forests, moving very quickly and being extremely difficult to put it under control. While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.
Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".

Answer:
The chromosome number of the somatic cells.
Explanation:
The body mainly consist of two types of cell known as somatic cells and germ cells. The somatic cells divide by the process of mitosis whereas germ cells generally divide by the process of meiosis.
The skin cells of the giant panda has 42 chromosomes. The skin cells are included in the category of somatic cells. The skin cells are diploid in nature and divides by the process of mitosis only. These cells remains diploid after the mitosis process.
Thus, the chromosome number of the somatic cells.
