KA3

Question 1

metabolic rate

Answer 1

measurement of energy consumed by an organism over a period of time

Question 2

how do u measure metabolic rate?

Answer 2

with a calorimeter or respirometer

Question 3

calorimeter

Answer 3

instrument used to measure heat energy produced in given period of time. Does this by measuring water temp before and after leaving the calorimeter

Question 4

respirometer

Answer 4

measurement of oxygen consumed or carbon dioxed produced

Question 5

oxygen delivery

Answer 5

as energy demands of an organism increase, the consumption of oxygen also increases

Question 6

circulatory systems in vertebrates

Answer 6

closed circulatory systems where blood is contained in a continuous circuit of blood vessels which are kept moving by a muscular pump (heart)

Question 7

fish gills

Answer 7

gas absorption occurs in the gills for fish as water flows over filaments oxygen diffuses down the concentration gradient into the blood

Question 8

double circulatory systems (vertebrates)

Answer 8

when the blood passes through the heart twice with high pressure and vigorous flow

Question 9

incomplete circulatory systems (amphibians+reptiles)

Answer 9

only 1 ventricle and some mixing of oxygenated blood for lungs and deoxygenated blood from the body occurs

Question 10

single circulatory systems (fish)

Answer 10

blood passes through a 2 chambered heart once for each circuit of the body. Blood flows to gills at high pressure but delivered in capillaries with low pressure.

Question 11

complete circulatory systems (vertebrates)

Answer 11

2 ventricles, separated by a septum. It enables endothermic vertebrates to deliver oxygenated blood to respiring tissues and to pick up heat energy released
