When a flu virus enters the body, the immune system creates antibodies made of polypeptide chains to fight the virus. The specif

ic shape of the protein allows it to bind to the virus and deactivate it. How does the antibody’s primary protein structure create the specific shape to bind to flu viruses?
A) The sequence of amino acids determines where hydrogen bonds form between segments of the polypeptide backbone. The hydrogen bonds and interactions between the side chains give the antibody its shape.
B) The sequence of amino acids determines where hydrogen bonds form between the amino acids’ side chains. The peptide bonds and interactions between the side chains give the antibody its shape.
C) The antibody’s primary structure consists of hydrogen bonds formed between segments of the polypeptide backbone. These determine how the amino acids’ side chains will interact, which gives the antibody its shape.
D) The antibody’s primary structure consists of disulfide bridges that twist and bend the polypeptide chain and give the antibody its shape. The antibody’s shape allows it to bind to a protein from the virus.

Answer: Option D

Explanation: The basic unit of antibody includes two identical light and heavy chains represented by L, H respectively. These heavy chains H and light chains L binds together by disulfide bonds to form a flexible Y shape.

Thus, the stem of the Y shaped antibody is called the constant region, and the tips are known as the variable region. It is these tips that bind antigen or protein from the virus.

Therefore, the correct option is D.

Metamorphic rocks are those which have been changed from one form to another by the high pressure and temperature environment of the Earth. "Metamorphism" means the process of changing form.

Phyllite is a type of foliated metamorphic rock.

Slate is a, fine-grained, clayey metamorphic rock.

Shale is a parent rock to slate and phyllite.

ale4655 [162]

Answer:

The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
