Liono4ka [1.6K]

Answer:

Mark pathogenic cells for destruction. (Ans. B)

Explanation:

Antibodies are generated by the plasma cells, and once these secreted, they attach quickly to the surface of the toxin and stop the toxin from infecting the normal body cell by blocking key extracellular sites.

Antibodies also help to mark pathogens for destruction by the help of macrophages or neutrophils and they are known as phagocytic cells because they are highly excited to macro-molecules complexed with antibodies.

the allele for white fur is revessive and the allele for normal fur is dominant the frequency for the normal fur allele is 0.60.
Mariulka [41]

Answer:

36% of wolves have normal fur.

Explanation:

Given , the allele for white fur is recessive and the allele for normal fur is dominant

Let "N" represents the allele for normal fur and "n" represents the fur for white fur.

As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"

Given ,

p = 0.60\\

Then frequency for dominant genotype will be "p^2"

So, Frequency for wolves with normal fur is

p^{2} \\0.60^2\\0.36

Percentage of the wolves with normal fur is

0.36*100\\= 36%

Lake Mojave is an ancient lake that has dried up and no longer exists in the Mojave desert in California. Which environmental co
Goshia [24]

The correct answers are:

- Decrease in rainfall in the Mojave desert;

The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.

- Decrease in runoff that flows into Mojave Lake;

If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.

- Increase in blocked streams that flow into Mojave Lake;

Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
