Major volcanic eruptions are examples of extreme events that leave behind the remains of living organisms that may form into rock layers. Scientists can use these rock layers to determine which organisms were alive at
different times on Earth.

Which statement describes the most likely location of a rock layer containing fossils of organisms living immediately before an
extreme event occurred?

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles

Select all that apply genes are specific nucleotide sequences occur in numbers that are the same as the number of chromosomes are located in a specific place on a chromosome determine the traits of an organism are units of rna
