elastic and collagen

Question 7

adipose

Answer 7

store fat

Question 8

regulators

Answer 8

use internal change to face external changes

Question 9

conformer

Answer 9

external changes results in internal changes

Answer 11

physiological changes that occur roughly every 24hr

Question 12

endothermic

Answer 12

generate heat by metabolism
birds
mammals

heat exchange mechanisms

Answer 16

radiation
evaporation
convection
conduction

Question 17

thermoregulation adaption

Answer 17

insulation
circulatory adaptation
evaporation
behavioural
adjusting metabolic heat production

Question 18

insulation

Answer 18

hair , fur , feathers , blubber
reduce heat loss
birds and mammals

Question 19

circulatory adaptation

Answer 19

many endotherm and some ectotherm
vasodilation:more heat loss
vasoconstriction:heat preservation
countercurrent exchange; marine mammals and birds

Answer 20

panting in birds and animals

sweating or bathing moisten

adjusting metabolic heat production

Answer 22

thermogenesis: adjustment of metabolic heat production to maintain body temp

shivering

biosynthesis

Answer 24

body growth
storage of material as fat
gamete production

Question 25

metabolic rate

Answer 25

amount of energy used in unit of time
determined by
-heat loss
-used O2 or carbon

Question 26

BMR

Answer 26

endotherm

metabolic rate in rest

Question 27

SMR

Answer 27

ectotherm

metabolic rate at rest at a specific temp
