An antigen is a biomolecule, such as a protein or sugar, that binds to a specific antibody. An antibody/antigen interaction may stimulate an immune response. Not every biomolecule is antigenic and not all antigens produce an immune response. B cells are the major cell type involved in the humoral immune response.
The key biomolecule involved in the immune system is a protein known as an antibody. These are produced by B cells and help the immune system recognize and destroy foreign substances like bacteria or viruses.
The biomolecule that has significant involvement in the immune system is a group of proteins known as antibodies or immunoglobulins. These antibodies are produced by certain types of white blood cells (B cells). They play a crucial role in the immune response by recognizing and binding to specific antigens such as bacteria or viruses, enabling other parts of the immune system to destroy these foreign substances more effectively. For example, if a person becomes infected with a virus, the immune system will produce antibodies specific to that virus. Once these antibodies attach to the virus, they basically mark it for destruction by other cells in the immune system.

The above answer is correct. Lampreys don't have jaws, possessing just cartilage.
Clams and squid have been evolving separately for a shorter time than clams and snails.
Clams and snails have more in common genetically than clams and squid.
Clams and snails are more similar in related structures than clams and squids.
Answer:
The correct answer is the second statement.
Explanation:
The molecular clock refers to a procedure in molecular evolution that associate the time of divergence between the two species with the number of molecular differences determined between the sequences of DNA or proteins.
The more genetically associated, the shorter will be the separation time between the two species. Due to this, as clams and squid are more closely associated it can be concluded that these species look more genetically identical, and have evolved distinctly for a brief time duration in comparison to the clams and snails.
Answer:
B. Clams and squid have been evolving separately for a shorter time than clams and snails.

Passive transport refers to the movement of molecules across cell membranes without requiring energy, aiding in maintaining balance within the cell. An example sentence is 'Oxygen molecules move from a region of high concentration to a region of low concentration via passive transport.'
Passive transport is a biological concept pertaining to the movement of molecules across cell membranes. Here is a sentence using the term: 'Oxygen molecules move from a region of high concentration to a region of low concentration via passive transport.' This means that oxygen molecules, without requiring energy, naturally move towards areas with fewer oxygen molecules. It is the cell's way of maintaining balance or homeostasis, a crucial aspect of cellular function.

B.the number of chromosomes in a cell
C.the size of the chromosomes
D.the genes of its chromosomes
Answer: The correct answer is-
D.the genes of its chromosomes.
Inherited traits are the characteristics of an organism that are transferred from parents to their next generation through genetic material (DNA).
For Example- Eye color, hair color, skin tone.
Gene corresponds to the unit of heredity that can be described as the segment of DNA that codes for a particular protein. They are present on the chromosome (thredlike structures composed of DNA).
The protein that is formed by gene, depicts a specific trait of the organism.
Thus, inherited trait of an organism are determined by the genes, located on the chromosome.
The genes of its chromosomes determines the inherited traits an organism has. Therefore, option (D) is correct.
Inherited traits are the characteristics of an organism that are passed down from one generation to the next through DNA. Some examples are the colour of your skin, your hair, and your eyes.
The unit of heredity known as a gene is defined as the section of DNA that codes for a specific protein. They can be found on the chromosomes, which are DNA-based thred-like structures.
The gene-produced protein represents a particular characteristic of the organism. Thus, the genes found on chromosomes control the inherited traits of an organism.
