Answer:
A. True
Explanation:
Hemoglobin is a protein and has two distinct types of polypeptide chains. These are called the alpha and beta subunits. The gene that code for the beta chain undergoes a mutation in a single base that causes sickle cell anemia. Here, adenine base in the genetic code for glutamic acid is substituted with a thymine base.
The genetic code for glutamic acid in the beta chain gene is GAG. The "A" is replaced with "T" and the new code "GTG" codes for valine. Therefore, the mutated hemoglobin has valine in place of glutamic acid. This makes these mutated protein molecules to form aggregates resulting in a change in the shape of RBCs carrying them.

Connective tissue.
- tissue that provides structure, support, and protection to other human tissues and organs. In addition to helping to transport nutrients and other substances between tissues and organs, connective tissue also helps to store fat and mend damaged tissue. A gel-like substance, fibers, and cells make up connective tissue.
- connective tissue is a set of tissues found throughout the body that help to keep the body and its organs in shape as well as to give internal cohesion and support. The more specialized and recognized variations—bone, ligaments, tendons, cartilage, and adipose (fat) tissue—as well as a variety of fibrous tissue types that differ only in density and cellularity are included in the connective tissues.
- The majority of the organs in the abdominal cavity are connected to the abdominal wall by a membrane strip called the mesentery.
Therefore, the correct answer is connective tissue.
