Gcse biology help me please i beg you ;o someone help me

are you y11 or y10?

this is my the rest of my revision i dont get please help ik its VERYYYYYYYYYYYYYYYYYYYYYYYYYYYYY YYYYYYYYY LONG. but do what you can and just put idk in the ones u dont know

💫could you write it like where it says explain could you develop and on some other points as well if necessary

thankyou so much idk how much i can thank you

B1.10 Exchanging materials
 Describe how the effectiveness of exchange surfaces are increased.
 Use ideas about surface area to volume ratio to describe why multicellular organisms need exchange surfaces
 Link ideas about diffusion to explain how the adaptations of exchange surfaces increase their effectiveness.

B3.1 Tissues and organs
 Define the terms tissue, organ and organ system.
 Describe the function of certain organs and organ systems.
 Identify tissues that make up organs.
 Suggest the function of glandular, epithelial, and muscular tissue in organs.

B3.2 The human digestive system
 Name all of the organs of the digestive system.
 Describe the functions of the organs.
 Summarise the process of digestion.

B3.4 Catalysts and enzymes
 Describe how enzymes are used in digestion.
 Explain how enzymes speed up reactions.
 Explain how enzymes control metabolism.
 Identify the independent variable in an investigation.
 Plan an experiment to investigate how different catalysts affect the rate of a reaction.


B3.5 Factors affecting enzyme action
 Explain why high temperatures and changes in pH prevent enzymes from catalysing reactions.
 Plan and carry out an investigation in order to gather accurate results.
 Plot a line graph and use it to draw conclusions about how temperature and pH affects the rate of an enzyme catalysed reaction

B3.6 How the digestive system works
 Explain why enzymes are needed for digestion.
 For each food molecule, name the enzyme that acts on it, where it is produced, and the products formed.

B3.7 Making digestion efficient
 Describe the functions of bile.
 Explain how acid in the stomach increases the efficiency of pepsin.
 Explain how bile increases the efficiency of fat digestion.

B5.2 Pathogens and disease
 Describe how bacteria and viruses cause disease.
 Explain how pathogens are passed from one organism to another.
 Suggest ways of preventing the spread of communicable diseases, referring to the transfer of pathogens.
 Describe how aseptic techniques are used to create an uncontaminated culture of bacteria.
 Explain the conditions required for bacteria growth in a school laboratory.

B7.1 Non- communicable diseases
 Classify diseases as communicable or non-communicable.
 State risk factors that are linked to an increased rate of a disease.

B4.4 Breathing and gas exchange
 Label a diagram of the gas exchange system to show some of the main structures.
 State that gas exchange happens in the alveoli.
 Explain in detail how adaptations of alveoli result in efficient gas exchange.


Key practical’s you will have carried out this academic year:
Required practical activity 1: use a light microscope to observe, draw and label a selection of plant and animal cells. A magnification scale must be included.

Required practical activity 3: investigate the effect of a range of concentrations of salt or sugar solutions on the mass of plant tissue

Required practical activity 4: investigate the effect of pH or temperature on enzyme activity.

Skills you may be tested on:

o Calculating mean.
o Identifying variables in an experiment.
o Plotting graphs with line of best fit.
o Describing trends of graphs.
o Using the formula: real size = image size magnification

If there’s a way i can send it to u through another app it would be much easierr

This is very long haha, don't you have a revision guide or textbook to help you? Im pretty sure these questions have come from the AQA biology third edition made from oxford.
You can also use freesciencelssons.

the spec is quite detailed:
http://filestore.aqa.org.uk/resources/biology/specifications/AQA-8461-SP-2016.PDF

do you have insta? or email? idkkkkkkkkkkkkkkkkkkkkkk insta will be long cuz its so tiny email should do just type it up in word and send the document but please could your write b4.7 blah blah
and like but bullet points and explain as much please tyyyyyyyyyyyyyyyyyy x

Ya your insta I’ll copy and paste it or try figure out somethingg

Ya your insta I’ll copy and paste it or try figure out somethingg

My insta is @elliekatesophia i got a A* in gcse biology last year happy to help u

i acc dont know this is the only thing i can use tbh... ;/

Use Seneca

i dont think this is exact to the spec im only in year 9

Still, Use Seneca

how do i find the specific info i need on it it will just give me 100 notes about the whole of active transport

Check the Spec.
