I need help on a study guide for my exam.

1) Describe how predation (a biotic limiting factor) affects population growth and decline.
2) How do the codons in a mRNA strand code for the amino acids of a protein?
3) Describe the reactants and products of the light dependent and light independent reactions. What happens in each stage?
4) Describe the process of crossing over in meiosis
5) How do x-linked and y-linked diseases pass onto offspring?

okay.
predation affects population growth and decline by the follwing. it can cause growth when a top consumer is made and n ther animal conusmes it giving a larger life rate. decline is possible when one animal is being hunted to much. in overall, this has a vast affect on population.
