In a cross between two doubly heterozygous Ursa gummi, we observe 415 Melting Ursa gummi and 50 Melting-resistant Ursa gummi. If the Melting phenotype is the dominant phenotype, make a decision as to whether these data are consistent with the duplicate dominant epistatic mode of inheritance. Make your decision based on a significance level threshold of 5%.

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 atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.
