AQA GCSE Biology Paper 2 Higher Tier [9th June 2023]

It was so weird I said casting shows evidence of past life and we can evaluate their characteristics and stuff and compare to life today to prove evolution occurred and then natural selection like how organisms with certain characteristics able to survive an environment are more likely to pass it down and keeps happening until eventually all organisms have that trait
Idk

Yeah that seems right tbh good work

last question 6 marker what did you lot put

I talked about fossils how they form , then talked about comparing structure of fossil to see how organisms change over time . I then talked about antibiotic resistance as understanding mutations causing evolution and natural selection. Also talked about microscopes and seeing feel divisions

Nitrogen ions are released by microorganisms during digestion into the soild. Roots absorb these via active transport, and they combine with glucose to form amino acids. These go on to form proteins for growth

Aaa I thought abt it but i didn't
I went on abt like decomposers and Co2 and nitrogen gets released trees absorb it for photosynthesis and it gets locked in and makes glucose for idk respiration or storage 😭😭😭

nah its community:
this is from google

community refers to all of the populations present inside a single habitat

population is number of organisms of the same species
question asked for all the organisms - didnt say they were the same species
