Answer:
a. Following an injury that breaks the surface of the skin. blood vessels dilate as a result of histamine release from mast cells and other damaged cells.
b. The blood forms a clot and upon drying, a scab forms a barriers between the body and the environment, while phagocytes work to clear the underlying debris from the wound site.
c. Blood vessels begin to re-grow into the wound while fibroblasts begin process of replacing the blood clot with Collagen
d. The remodeling phase then occurs as fibrosis and regeneration of tissues may continue for prolonged period of time.
Explanation:
Hello. Although you did not have all the answer options for the blanks presented in the sentences above, it is possible to conclude that the words in bold are the most appropriate to fill these spaces.
That's because when we cut ourselves, the blood vessels on the surface of our skin rapidly dilate, allowing a flow of blood to be observed. This dilation is accomplished by the release of histamine, which is released by mast cells, which are glands that regulate the immune response. At this point, it is important that any impuzera or microorganism, close to the wound site, is removed and this site undergoes cleaning. This is done by phagocytes, which are intended to prevent the cut from becoming the entrance to a bacterial infection.
Then the blood vessels begin to move and grow again across the wound, with the aim of covering this opening. In this comment, fibroblasts begin to apply collagen and replace the blood clot formed to prevent blood loss. Collagen will be responsible for maintaining the skin and tissues that will be rebuilt in the remodeling phase.
4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.
Hence, the given statement is true.
5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.
Hence, the given statement is true.
Answer:
Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is the visible spectrum that is visible to the human eye and is responsible for the sense of sight.
The sustainable use of land means using the spare land in such an activity which supports the society and benefits the environment.
In such a situation if a land is found spare then a park should be constructed on it.
This will create an recreational activity spot for the society and they will be able to spend their leisure time with fun.
Also there will be less pollution and harm to environment will be lowered by greenery and trees in the park.
