1

decreases blood flow which limits heat loss

vasoconstriction

2

blank animals have higher metabolism to keep warm

smaller

3

blank animals have lower metabolic rates to retain heat better

large

4

tissue that forms the outer protective covering of a plant organ

dermal tissue

5

fills the interior of a plant organ; photosynthesizes and stores the products of photosynthesis

ground tissue

6

tissue that transports water and sugar, the product of photosynthesis, in a plant and provides support

vascular tissue

7

root xylem and phloem are in a ring in the root of a blank

monocot

8

the root phloem is between the arms of xylem in roots of blank

eudicots

9

the vascular bundles are scattered in the stems of blank

monocots

10

the vascular bundles are in a distinct ring in blank

eudicots

11

a carrot is an example of a blank

taproot

12

the growth between terminal bud scars is called a blank

twig

13

use of energy metabolism to produce heat

thermogenesis

14

thermoregulation is controlled by the blank

hypothalamus

15

blank is used by us to keep us warm when cold

shivering

16

in the hypothalamus there is a blank center that kicks in when the body temp increases

heat losing

17

in the hypothalamus there is a blank center that kicks in when the body temp decreases

heat promoting

18

these cause a rise in temperature in the body and produce a fever

pyrogens

19

a state of dormancy of the body and an extreme case is blank

torpor, hibernation

20

three groups of heteretrophs

herbivores, omnivores, carnivores

21

eats hard animals

durophagous

22

substances that an animal cannot manufacture for itself but are necessary for health

essential nutrients

23

four essential nutrients

vitamins, amino acids, unsaturated fatty acids, minerals

24

specialization occurs when the digestive tract has a separate blank and blank

mouth, anus

25

function is absorption in digestive system

small intestine

26

function is to concentrate wastes in digestive system

large intestine

27

function is waste storage and elimination in digestive system

cloaca

28

four accessory organs of digestive system

salivary glands, liver, gallbladder, pancreas

29

pancreas makes this which stops acid from stomach from breaking down the intestines

bicarbonate buffer

30

four layers of gi tracts

mucosa, submucosa, muscularis, serosa
