Imagine that you have the dna sequences from the intron of a gene in three species called a, b, and c. species a and b are most closely related, while c is more distantly related. the sequences of a and b differ by 18 base pairs, a and c differ by 26 base pairs, and b and c differ by 28 base pairs. fossils show that species a and b diverged about 1.2 mya, but there is no fossil evidence as to when the most recent common ancestor of all three species lived. use the genetic data to estimate that date. what assumptions are you making to get this estimate?

Part a - prefixes, roots, and suffixes match these prefixes, suffixes and roots to their meanings. phospho- angio- -uria -tropic -phag- a. the word root means blood or lymph vessels. b. the word root means urine. c. the word root means feeding or eating. d. the word root means phosphate or phosphorus. e. the word root means attracted specifically to the specified organ or tissue. part b – match these vocabulary terms to their meanings. gonadotropic polyuria angiotensin ii polyphagia phosphodiesterase upon the release of renin, is produced and stimulates vasoconstriction and the release of aldosterone. fsh and lh are examples of hormones, which target the ovaries or testes. an enzyme that degrades second messengers like camp or cgmp is . overproduction of urine, or , is a sign of diabetes mellitus. overeating, or , is a sign associated with diabetes mellitus.
