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.
Answer:
Heterozygous (AB) for the STR locus = Allele (A) x allele (B) = 0.02 x 0.03 = 0.0006
Explanation:
The probability of the heterozygous genotype AB is equal to the product of the probabilities of these two independent events (i.e., independent events represented by allele segregation)= 0.02 x 0.03 = 0.0006
Two similarities are: Volume and Shape
