Explanation

Question 21 of 40

1

Select from the dropdown lists to complete the text.

diffusion rate is affected by three things.
1) the ( concentration gradient., cell membrane. ) the bigger it is, the faster the rate of diffusion
2) the surface area. the bigger it is, the ( faster, slower ) the rate of diffusion
3) temperature. the higher it is, the more ( energy, nuclei ) the particle has.

Explanation

Question 22 of 40

a student says,
"if i was to drop a droplet of ink into water, osmosis would take place, causing all of the water to eventually turn the colour of the ink. This is true as osmosis is the movement of water particles."

The potato experiment:
this experiment involves cutting up a potato and leaving it in differently ❌ solutions of ❌ and ❌. It shows the effects of ❌ - if the potato wedges have ❌ in mass it means that water has been absorbed by the potato by osmosis. if water has been drawn out, they will have ❌ in mass. you then plot the figures on to a ❌

Explanation

Question 31 of 40

1

Select from the dropdown lists to complete the text.

these are the ( two, three ) stages of the cell cycle.

stage 1: DNA is spread out in long ( strings, lines. ) before it divides, it ( increases, decreases ) the amount of sub cellular structures, such as ( mitochondria, cell membrane ) and ribosomes. it then ( duplicates, destroys ) its DNA which is copied and forms ( "X", "o" ) shaped chromosomes.

stage two: ( mitosis, the actual splitting of the cell ). the chromosomes line up at the ( centre, sides ) of the cell, and cell fibres pull them apart. the two arms of the chromosome is put on either side of the cell membranes form around each set of chromosomes. these become the ( nuclei, parent ) of the new cells - the nucleus has divided. lastly, the ( cytoplasm, ribosomes ) and ( cell membrane, nucleus ) divide.

the cell has now produced two daughter cells.

a person with the disease "" may experience lower while doing physical exercise. This disease affects the , damaging the walls. the reason for this symptom is since the walls of the alveoli, there will be a surface area. a surface area leads to a lower rate of of oxygen. the lower the rate of the less . respiration is what gives us therefore the person will experience lower .

1

Fill the blank spaces to complete the text.

here are some adaptations to make gas exchange easier.
1) : this allows only a short distance to be needed for diffusion to take place.
2) : so a lot can diffuse at once.
3) : good blood supply can get in and out quickly
4) : for dissolving gasses
5) : tiny holes in the leaf. they have cells around them called guard cells which control the size of the stomata and prevent wilting.

Explanation

Question 36 of 40

Fill the blank spaces to complete the text.

LEAVES: carbon dioxide diffuses into the in the leaf, then to the cells where happens.
the leaf's structure is adapted so that this can happen easily:
1) the of the leaf is the gas exchange surface and is covered in
2) the size of stomata are controlled by
3) the increases surface area
the walls of the cells inside the leaf form another of which air spaces to increase

REMEMBER! PLANT CELLS need and take out
