Answer:
B. 20%
Explanation:
The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).
Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.
This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.
Since they are equal in amount, there must be 20% of each.
Therefore the answer is B. 20%
There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.

Loess is a geologically material which is usually yellowish or brown in color and consisting of tiny mineral particles brought by wind to the places where they now lie. It is a sedimentary deposit of mineral particles which are finer than sand but coarser than dust or clay, deposited by the wind. Loess is a type of silt which forms fertile topsoil in some parts of the world. The soil has few clay particles to hold it together. It is composed mainly of quartz crystals which slide easily against each other, and is therefore very subject to erosion.
Answer:
7
Explanation:
There are always half the chromosomes in sex cells.
Answer:
option d. end capping
Explanation:
The ABP or actin binding proteins are attached with actin. The actin filaments are attached with ABP. The actin binding proteins provide large number of monomers of actin for polymerization. The ABP also help in new filament assembly. The ABP function in promoting the process of elongation. The ABP allows filament severing/depolymerization.
The end is attached with cap having the pointed or barbed ends. The barbed end gets attached with capping proteins (CP) thus blocking polymerization. So, ABP are not involved in end capping. Thus, option d is incorrect.
