Answer:
The correct option is D. Genes determine the trait of an organism.
Explanation:
Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.
Option A is false because each gene is made up of different nucleotide sequences.
Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.
Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.
Option E is false because genes are not units of RNA. Genes are made up of DNA.
The skin is an example of a non-specific defense.
For example, bacteria or diseases have trouble entering a healthy person's skin because it is formed by closely packed cells with multiple layers and a substance called keratin that protects is.
On the other hand, the immune system is a specific defense mechanism.
When bacteria is able to enter the body in cases of fever for example, the immune system is activate and sends out protector cells such as the white blood cells to combat infection.
