Ineed i can't do this does anyone know how to do this if so

I know the first two for the fill in:

1. I believe it's energy

2. Diaphragm

Multiple choice:

1. I believe it's 3, trachea

2. I think it's 3, respiration

There's quite a lot of questions, but I hope this helps :)

not sure but try c two haploid cells

explanation:

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
