Ques:Answer the following question given this paragraph: The process of producing mature sperm is called spermatogenesis . Sperm are produced in the seminiferous tubules of the testes and become mature in the epididymis . The entire process takes about 9 to 10 weeks. You can watch an animation of spermatogenesis at this link: http://wps. aw. com/bc_martini_eap_4/40/10469/2680298. cw/content/index. html . Q: The process of producing mature sperm is called what?

Answer the following question given this paragraph: Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Oxygen is essential for cellular respiration for all aerobic organisms. It also maintains the ozone layer that helps protect Earth's life from damaging UV radiation. Removal of carbon dioxide from the atmosphere reduces the greenhouse effect and global warming. Q: The ozone layer protects the earth from what? Choices: - pollution - light waves - radio waves - uv radiation A:
uv radiation
