What is the difference between a dominant and
recessive allele? Give an example of each.

the difference between dominate and recessive alleles are that the dominate allele will be expressed if it is present, while the recessive allele will only be expressed in the absence of the dominate trait

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
