Chromosomes Are Concerned With :

A: Respiration
B: Growth
C: Transmission Of Heredity Characters
D: Assimilation

The answer is: C

Explanation

Chromosomes are primarily concerned with the transmission of hereditary characters from one generation to the next. Chromosomes are structures that contain genetic material in the form of DNA (deoxyribonucleic acid). Each chromosome carries a unique set of genes, which determine an individual's traits and characteristics, such as eye color, hair color, and height.

During cell division, chromosomes replicate and then separate, with each new cell receiving a copy of each chromosome. This ensures that each new cell has the same genetic information as the original cell. Any mutations or changes to the DNA sequence that occur during replication can lead to variations in traits and characteristics.

While chromosomes may indirectly influence other cellular processes such as growth, respiration, and assimilation, their primary function is to carry and transmit genetic information.
