Peyer's patches (aggregated lymphoid nodules)
Explanation:
Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.
Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.
A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque. The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.
Answer:
I took this in middle school option 3
Explanation:
The right option is; d. 366 people/mi^2
Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.
From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.
Population Density = Number of People / Land Area.
Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.
Therefore, the population density of China is 366 people per square mile.
Then the mice would not be infected as the DNA is destroyed by the enzyme ....so S type have no use and can't transfer it's DNA ....so mice survive !
