Suppose a geneticist isolates two bacteriophage mutants. One mutation causes clear plaques (c), and the other produces minute pl
Nesterboy [21]

Answer:

The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.  

Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.  

The total recombinants from 1000 plaques will come out to be 80,  

Thus, the recombinants of each type will be 40.  

Total parental type will be 920, and therefore, each parental type count will be 460.  

Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.

Aquaporins would be expected to _____ in numbers when _____ is present in the blood
dangina [55]

Aquaporins would be expected to increase in numbers when there is an insufficient amount of water present in the blood.

Aquaporins are a type of proteins which are present in the integral membrane of the cells. They act as channels and help in the transport of water and small solutes across the membrane.

Whenever there is insufficient amount of water present in the blood, the antidiuretic hormone or the ADH responds. The aquaporins increase in number in the blood. They allow the transcellular reabsorption of water. Due to this fact, more water is able to escape from the collecting tubules and enter the blood.

What evidence can be examined when determining common ancestry amongst hominids?
mars1129 [50]

We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.
