Kevin writes this description on the blackboard.

“this is a way of writing a value as the product of a number, n, between 1 and 10 and a power of 10.”

what is kevin describing?

[a] significant figures

[b] common logarithm

[c] multiplication factors

[d] scientific notation

The right option is; [D] scientific notation

Kevin is describing scientific notation.

Scientific notation is a special method of writing numbers (values) that are very small or very large. Scientific notation is used when a number between 1 and 10 is multiplied by a power of 10. For example, 800 can be written in scientific notation as 8 x 10^2.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
