What is relative dating? O A. A method of determining the age of a rock layer by comparing its
position to other rock layers
B. A method of determining the age of a rock layer based on the
amount of radioactive material that remains in the rock
C. A method of determining the age of a fossil that estimates how
closely related various fossil organisms were
D. A method of determining the age of a fossil that estimates the
age of the organism at its death

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. estimated age). (O A. A method by determining the age of a rock by comparing its position to other rock layers.)

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
