Which statement best describes the role of a gene in the production of an organism traits? a. one strand of a gene serves as the template for making an mrna molecule. b. a gene has versions called alleles so that it can produce different traits. c. a gene unwinds and becomes a template that organizes amino acids. d. one strand of a gene exits the nucleus and goes to a ribosome to pair with a protein.

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.

explanation:

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
