Answer;
a segment of chromosomal DNA
Explanation;
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Explanation:
The correct answer is: D. all of the above
A macromolecule is a large molecule present in the cell, composed of a huge number of monomer units with the various functions. There are four main groups: proteins (monomers are amino acids), nucleic acids (monomers are nucleotids) , lipids (monomers are free fatty acids) and carbohydrates (monomers are simple sugars such as glucose).
Some of their functions:
• Provide structure on the cellular levels-lipids (phospholipids) are the main components of the cell membrane;
• store genetic material-nucleic acid (DNA, RNA) are the carriers of genetic information
• store energy-starch is energy source in plants;
• enzymes -proteins often are with the functionin metabolism
• etc.
Answer:
d. Musculoskeletal
Changes in musculoskeletal body system affect overall mobility increasing the propensity of falling?
Explanation:
Problems in the musculoskeletal system can affect mobility through restricting the range of motion and strength, increasing the chances of falling. The changes to the neurologic system damages cognitive functioning.
Changes to the hepatic system can affect mental status while changes to the cardiopulmonary system can affect activity tolerance.
