Answer:
The correct answer is C. <em>"Cartilage, smooth muscle layers, mucosa, circular muscle". </em>
Explanation:
The intestine wall is conformed of 4 layers: mucosa, submucosa, muscular and serous.
- The mucosa layer is composed of cylindrical simple epithelium that shapes tubular glands named Lieberkühn crypts and villus, these las one in charge of absorption. The crypts are invaginations of the epithelial surface and they have the stem cells. The epithelial cells renew constantly, so cells divide in the base of the crypts and then they move to the superior portion of the digestive tube, where they die. This layer also has a basal sheet and a thin muscular sheet.
- The submucosa layer is composed of dense connective tissue, with adipose tissue located in some specific areas and large-caliber blood vessels.
- The muscular layer is composed of two bands disposed perpendicularly between them, the <u>internal thick circular muscle</u> and the <u>external thin longitudinal muscle layer</u>.
- The serouse layer is composed of a very thin connective tissue that in some points continues with the peritoneum.
The correct answer is:
Emigration because it means people are moving out, causing the population to decrease along with a death rate.
Explanation:
if there are a high death rate and a large amount of emigration, populations will likely decrease. Emigration relates to an experience when an individual walked out to another place because of some reasons ( the most common one are: Rare resources, societal problems, depression, or solely because they required to try out their fate).
Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)
-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)
search "DNA base pairs" and go to images for better understanding
I am not 100% sure but I think it’s A sorry if I am wrong but a answer is batter then no answer lol have a good day
