4. How does the life of a sperm cell vary among the mosses, ferns, gymnosperms and angiosperms?

answer; i believe that the correct answer is (lung);

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
