At location a in the figure above, the individual with these two paired chromosomes is:

a) homozygous for the dominant phenotype
b) heterozygous for the recessive allele
c) homozygous for the dominant allele
d) heterozygous for the dominant phenotype
e) homozygous for the recessive allele

Below, the levels of organization in a multicellular organism are shown from least to most complex. which level of organization can be described as several different types of tissues working together to perform a common task?

Why do leaves change color in the fall? green pigments break down and no longer mask the color of chlorophyll. chlorophyll breaks down and no longer masks the colors of other pigments. red- and yellow-colored pigments grow and mask green-colored chlorophyll. green-colored chlorophyll breaks down and turns red and yellow.

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. assume all are homozygous. agouti x albino a) 1/2 albino, 1/2 agouti b) all agouti c) 3/4 agouti, 1/4 albino
