Answer 2

hybridoma

Question 3

what are monoclonal antibodies produced from

Answer 3

a single clone of hybridoma cells

Question 4

lack of nitrate ion

Answer 4

stunted growth- bcz nitrate is needed for protein synthesis

lack of magnesium

Answer 5

chlorosis-magnesium required to make chlorophyl

Question 6

Answer 8

breathing and heart rate

Question 9

Answer 9

myopia

Question 10

long sightedness

Answer 10

hyperopia

Question 11

lenses for hyperopia

Answer 11

convex-focuses light before it enters the eyes

Question 12

lenses for myopia

Answer 12

concave-unfocuses light before it enters the eye

Question 13

Phototropism

Answer 13

shoots growing towards light

Question 14

gravitropism

Answer 14

plant roots grow towards the force of gravity

Question 15

importance of giberellins

Answer 15

initiate seed germination

Question 16

importance of ethene

Answer 16

controls cell division and ripening of fruits

Question 17

uses of auxins

Answer 17

weed killers
rooting powders
promote growth in tissue cultures

Question 18

uses of giberelins

Answer 18

end seed dormancy-germinate early
encourge plants to flower
larger fruit

Question 19

uses of ethene

Answer 19

ripening

Question 20

regulation of body temp when too hot

Answer 20

sweat
vasodialation-blood vesseles dialate more blood flows-energy can transfer out of blood

Question 21

regulation of body temp when too cold

Answer 21

vasoconstriction-less blood flows through capillaries
shiver-skeletal muscles contract-rate of muscle respiration increases to release energy for shivering this releases heat

Question 22

deamination

Answer 22

liver breaks down excess amino acids into ammonia

Question 23

What does ADH stand for

Answer 23

anti diuretic hormone

Question 24

What does ADH do

Answer 24

excreted by pituitary gland when blood concentration is too high (water volume in blood is too high)

Question 25

what is kidney dialysis

Answer 25

when levels of water/ions need to be reajusted using a machine as the kidneys fail

Question 26

what does DNA stand for

Answer 26

deoxyribonucleic acid

Question 27

what is DNA made of

Answer 27

It is a polymer of molecules called nucleotides

Question 28

stage one of protein synthesis

Answer 28

transcription
base sequence of gene is copied in a complimentary template molecule (Message RNA or mRNA)
this then passes from the nucleus into the cytoplasm

Question 29

stage 2 of protein synthesis

Answer 29

translation
happens in the cytoplasm
mRNA molecule attaches to a ribosome

Question 30

what is the base contained by DNA called

Answer 30

thymine

Question 31

what is the base contained by mRNA called

Answer 31

uracil
