physical characteristics that you have such as shoe size, eye colour

Genotypes are
inherited
3 of 29
They are
allelles you have like eye colour, certain diseases
4 of 29
Alleles are
an alternate form of a gene found at the same position on a chromosome
5 of 29
2 genetic disorders
Polydactyly, cystic fibrosis
6 of 29
Polydactyly
extra fingers or toes, caused by a dominent allele, can be passed on from one parent
7 of 29
Cystic fibrosis
Affects cell membranes, caused by a recessive gene- ff means you have it, Ff means you don't but you're a carrier. Must be inherited from both parents.

Veins carry what type of blood
deoxygenated. They carry blood TO the heart. Have valves to stop back flow of blood. Flows at a low pressure
9 of 29
Arteries carry
oxygenated blood. Carry blood AWAY from the heart. No valves so more pressure. Flows at a high pressure.
10 of 29
Capillaries
connect the veins and the arteries. Have a low BP and allow for the exchange of materials

What is glucagon
a hormone which converts glycogen into glucose (when blood sugar levels are too low)

4 adaptations of cells in the small intestine
Large SA, thin lining, good blood supply, moist lining

True or false: Active transport moves molecules using transport proteins.
True
14 of 29
Solute molecules move out of the cell by osmosis.
False
15 of 29
In osmosis, water moves from a dilute to a concentrated solution.
True
16 of 29
Dilute solution contains
more water than sugar
17 of 29
A concentrated solution contains
more sugar than water
18 of 29
Water is the
solvent
19 of 29
Sugar is the
solute
20 of 29
The cytoplasm contains a high
concentration of salts and sugars
21 of 29
If the concentration of the outside of the cell is different to that of the inside then
osmosis occurs
22 of 29
If the cytoplasm is too concentrated the water moves .... which .....
in, restores balance
23 of 29
Cells can burst as well as shrinking. This means the cell can no longer
survive
24 of 29
In plants, water moves into the plant cells by
osmosis
25 of 29
This causes the vacuole to
swell
26 of 29
When the pressure is at it's maximum the cell is
turgid
27 of 29
This
supports the plant
28 of 29
If the solution outside of the plant is more concentrated then the cell's content
then the water will move out of the cells which won't support the plan t
