There’s lots of questions for each topic on here https://www.physicsandmathstutor.com/ x

how may a person with AIDS take longer to recover than a healthy person to a infection?

Where are protease/amylase/lipase enzymes produced?
What is the function of the liver?
Explain the role of bile?
Give two disadvantages of adult stem cells.
Describe how statins can help treat Coronary Heart Disease
What are two adaptations of the small intestine?
Give one condition which can be treated with a pacemaker
What is the first stage of mitosis?
What is osmosis?
Give one similarity and one difference between Active Transport and diffusion
Describe 3 substances carried in the plasma
What is the role of red blood cells
How are root hair cells adapted to their function
How are nerve cells adapted to their function
Give 2 risk factors of Coroanry heart disease
Give 2 differences between malignant and bending tumours
What is the balanced equation for photosynthesis
Give 2 uses of glucose produced in photosynthesis
What is energy from respiration used for?
What is a symptom of nitrate deficiency in a plant?
Why is a symptom of phosphate deficiency in a plant

I’d say bexusse they have already had the aids so it already has its genetic characteristics so will fight it off faster and stronger

not quite, AIDs damages ones immune system so there would be less white blood cells producing antitoxins and antibodies to fight the infection
therefore taking longer to recover

Isn’t protease produced in the stomach, the rest I think the same place idk.
Doesn’t it produce bile to neutralise stomach acid and stores it in the gall bladder.
To break down food molecules.
Umm, that’s a hard one, I’d say 1) they went ethically approved because people think they arnt from living people although it duplicates it, it is not from the person 2) idk doesnt It require a lot of energy to manipulate it to fit the cell criteria.
The stations like move the fat away so it unclocks it and forms a net mesh type of thing which allows boood to flow sufficiently.
Large surface area and villis to help diffusion.
This was on my mock and I just put heart attack.
Growth?
The movement of water from low to high concentration gradient through a partially permeable membrane.
AT-requires energy, diffusion- high to low conc
Havnt got a clue I thought it was just yellow fluid.
To oxidise blood idk.
Large surface area to stabilise turgidity
They have synapses to help them send electrical signals and recycle them through at neurontransmitter.
Obesity and lack of exercise
Malignant is when the tumour moves and Beinign is just a tumour I belive.
2Co2+2h20 -> c6h12o6 +2o2
Glucose is transported in phleom so it allows the plant to respire, also glucose is useful in providing energy for the plant to eat and grow.
Stunted growth
I would’ve said discolouration like black or something

Yep well Im gonna fail, can someone mark this and see how bad I would do

Ahh. I’m relaly bad with immunity, litelely it just doesn’t make sense to me. Thank you for your help

So the disadvantages of adult stem cells is that they are extremely painful to extract from the bone marrow and that they are already partially differentiated meaning they can only specialise into a similar cell(eg stem cell from the lung can only specialise into lung cells).

So the bile neutralises the acid from the stomach in the small intenstine which provides the alkaline conditions needed in the small intestine. It also emulsifies fats to provide a larger surface area for the lipase enzymes to work

Red blood cells transport oxygen for aerobic respiration. They contain haemoglobin - a red protein which binds with the oxygen to form oxyhemoglobin.

The function of root hair cells is to absorb water into the transpiration stream. It has long hair-like extension which increase the surface area to absorb water via osmosis.

Nitrates are needed to make protiens for healthy growth, but the symptom of the deficiency is pale green or yellow leaves due to a shortage of chlorophyll



Statins are actually a drug which stop the liver producing as much cholesterol which blocks the coronary vessel.

Yes, the pacemaker question was from the AQA past paper and the correct answer is an irregular heartbeat, or you could say fibbliration or arythmia.

I am pretty sure that in the blood plasma there is amino acids, proteins, urea, carbon dioxide, and platelets--correct me if I'm wrong.

np and good luck, lets ace this exam!
