Acommon feature of all organisms in the animal kingdom is that they are: terrestrial autotrophic multicellular segmented question 5(multiple choice worth 2 points) (6.04 mc) evolutionary relationships between different species of animals are best determined by: amount of common dna sequences ability to interbreed with each other geographic proximity of habitats comparing methods of locomotion question 6(multiple choice worth 2 points) (6.04 mc) animals that arose later in evolutionary history share which characteristic? flagellated cells cells organized into tissues radially symmetrical bodies protostome development question 7(multiple choice worth 2 points) (6.04 mc) research from several sources suggest that one type of sponge is more closely related to non-sponge animals than it is to other sponges. what does this suggest about classification in the animal kingdom? sponges do not belong in the animal kingdom. there is no logical system of classifying animals. a common ancestor of animals was a sponge-like animal. recently discovered animals are not able to be classified in the current system.

Glutamic acid: hydrophilic or hydrophobic? positive, negative, or neutral? valine: hydrophilic or hydrophobic? positive, negative, or neutral?

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.

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
