Which of the following lymphoid organs is NOT matched with its function? bone marrow: a) form lymphocytes Peyer's patches: b) site of B cell maturation thymus: c) site of T cell maturation spleen: d) remove old red blood cells

Peyer's patches: b) site of B cell maturation

Explanation:

B lymphocytes are produced in the bone marrow and get mature in the bone marrow only so the site of B cell maturation is bone marrow, not Peyer's patches. B cells produce antibodies that help in destroying microbes.

Peyer's patches are lymphatic tissue mass which is found especially in the mucosa and submucosa of the ileum. This lymphoid organ has a large number of B lymphocytes which monitors the intestinal bacteria and prevents the growth of pathogenic bacteria in the intestine.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
