Answer 3

reproduction

Question 4

structures of reproductive system

Answer 4

gonads and ducts

Question 5

renal corpuscle is made up of

Answer 5

glomerulus and renal capsule

Question 6

eliminate N as ammonia directly

requires water

Answer 6

ammonotelism

Question 7

eliminate N as uric acid

Answer 7

uricotelism

Question 8

use uricotelism

Answer 8

birds and reptiles

Question 9

eliminate N as urea

Answer 9

ureotelism

Question 10

uses ureotelism

Answer 10

mammals

Question 11

maintaining body/ body fluid water and ion levels

Answer 11

osmoregulation

Question 12

freshwater species osmoregulation problems

Answer 12

water comes in because body fluids are hyperosmotic to environment
eliminate excess water by dilute urine

Question 13

seawater species osmoregulation problems

Answer 13

outward water flux via osmosis
body fluids are hyposmotic to environment
preserve water with concentrated urine and drinking water and salt glands

Question 14

movement of water/solutes into renal capsule

Answer 14

glomerular filtration

Question 15

along uriniferous tubule

Answer 15

selective secretion adds to filtrate

selective reabsorption of some components of filtrate

Question 16

freshwater fish and amphibians

Answer 16

kidneys with large well-developed glomeruli

produce a lot of glomerular filtrate

Question 17

lack glomeruli/renal capsule

Answer 17

aglomerular kidneys

Question 18

saltwater species…

Answer 18

have aglomerular kidneys

lack distal tubule

Question 19

what adaptation do mammals and birds have to conserve water

Answer 19

glomerular kidney with loop of henle

Question 20

characteristics of loop of henle

Answer 20

allows creation of osmotic gradient
Na reabsorbed in loop creates hyperosmotic region
water reabsorbed by osmosis at collecting duct

Question 21

Dehydration stress

Answer 21

antidiuretic hormone release

Question 22

job of antidiuretic hormone

Answer 22

allow for reabsorpbion of more water

Question 23

body fluid osmotic concentration equals that of the environment

Answer 23

osmoconformer

Question 24

tolerate a range of salinities

Answer 24

euryhaline fish

Question 25

tolerate a narrow range of salinities

Answer 25

stenohaline

Question 26

ion reabsorption

Answer 26

kidney uriniferous tubule

Question 27

ion elimination ins SW fish or ion uptake in FW fish

Answer 27

gills

Question 28

ion elimination

Answer 28

rectal gland

Question 29

eliminates salt for marine reptiles and birds

Answer 29

salt glands

Question 30

uptake ions for aquatic amphibians

Answer 30

skin
