Alinear piece of viral dna of 8 kb can be cut with either of two restriction enzymes (x and y). these are subjected to electrophoresis and produce the following bands:
cutting the same 8 kb piece with both enzymes will result in bands at 4.0, 2.5, 1.0, and 0.5.
of the possible arrangements of the sites given below, which one is most likely?

a) y between 2 & 3, x between 4 & 5, and y between 6 & 7.
b) y between 2 & 3, x between 3 & 4, and y between 7 & 8.
c) x between 3 & 4, y between 4 & 5, and y between 5 & 6.
d) y between 2 & 3, y between 3 & 4, x between 4 & 5.
e) y between 0 & 1, x between 3 & 4, y between 5 & 6.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
