B. Decrease. The shrew population is dependent upon the grasshoppers as a prey item. A decrease in the available prey would result in a decrease in the predator population due to lack of resources to support the current population.
I believe the answer is plants make flowers to attract insects because, plants do nit store carbohydrates, meat does, and we cant use plants to create fossil fuel. The only plant fibers we use for clothing is cotton so that is very limited in the wide aspect of things.
Answer:
G - 21%
T - 29%
A - 29%
Explanation:
Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.
From the information given, C is 21%
Therefore G is also 21% of the genome as C is bound to G, the therefore are the same proportion.
C and G make up 42% of the genome (that 21% + 21%).
The remaining 58% (100%-42%) is made up of A + T
Similarly the proportion of A is equal to that of T,
Hence A is 29% (half of 58%) and T is 29%.
Answer:
a. methylation at lysine 9 or 27 of histone H3.
Explanation:
Methylation causes the switching off of genes using steric hinderance to prevent access to DNA.
