I WILL GIVE BRAINLIEST Which statement best describes why radioactive atoms can be used to date
materials?

A. The number of radioactive atoms in a substance increases over
many years.
B. The ratio of radioactive atoms to other kinds of atoms changes
over time.
C. Nonradioactive atoms in rocks eventually turn into radioactive
atoms.
D. The Sun interacting with atoms in a rock causes new atoms to
form over time.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
