Answer:
<em>The correct option is cell surface markers.</em>
Explanation:
The immune cells of our body detect foreign particles and generate responses so that our body can get rid of them. The foreign particles are often termed as antigens.
The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.
Answer:
Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases. Hence, nucleic acids are made up of nucleotides.
Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.
Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.

Answer:
Due to absorption of more water.
Explanation:
A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.
