Explain the stages of tissue repair and fill in the blanks.
svp [43]

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.

Which type of change would be more likely to have se­vere consequences—substitution or deletion? Why?
ludmilkaskok [199]

While both will equate changes in a genetic chain, deletion would have more severe consequences.  A substitution mutation usually only causes minor disorders and diseases, like sickle cell anemia.  Whereas deletion causes much more serious diseases, like cystic fibrosis, and turner syndrome which is  where a female is born with only one X chromosome.

Codon refers to nucleotide triplets of mRNA that serve to specify the amino acid sequence of proteins. There are total 64 genetic code that specify 20 standard amino acids found in proteins. All codon together make genetic code. For example: AUG is codon that specify amino acid "methionine". AUG codon also serve as initiation codon during initiation of protein synthesis.
