1. What is the relationship between base pairs A, C, T, and G in determining an individual's
phenotype?

The base pairs are what makes up an individual's genes.

Check below for further explanation.

Explanation:

The base pairs A, C, T and G are the basic molecules which makes is the DNA of individual.

The genes of an individual which determines the phenotypical expressions found in an individual such as eye colour, height, etc, are functional units found in the DNA.

Therefore, the arrangement of the base pairs determines the gene present in an individual and thus, the individual's phenotype.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
