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.
Answer:
Stress
Explanation:
Environmental stressing agent such as starvation or exposure to toxic chemicals may cause the Phage Lambda to excise and enter the lytic cycle.
Answer:
The cell is eukaryotic because it contains mitochondria.
nucleus
Explanation:
Explanation:
The purines are ribose and deoxyribose
In chemical reactions involving enzymes, the substrate proteins are huge molecules that will only react with each other if they're aligned just the right way. If they are permitted to interact with the enzymes present, the won't collide and react often enough for the reaction to do any good.The enzymes align the molecules, basically acting like "molecule shepherds," showing them the way they need to react.This speeds up the reaction greatly, making things like digestion possible. Hope this is helpful
