In a sample of yeast dna, 31.5% of the bases are adenine (a). predict the approximate percentages of c, g, and t. explain.

T would be 31.5% - the same as A. C and G would be about 18.5% each. A & T and C& G are always found in about the same percentages of each other. A = T (Total of 63%, subtract from 100 = 37% which will be equally shared by G and C at 18.5)

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.

Iguess i would say diagrams would be most difficult subject too correct
