1) four chromosomes as a result of meiosis
2) four chromosomes as a result of mitosis
3) eight chromosomes as a result of meiosis
4) eight chromosomes as a result of mitosis
Question #6: All types of asexual reproduction involve the process known as
1) mitosis
2) fertilization
3) meiotic division
4) aging

2) hormones
3) starches
4) minerals
Question #8 Which part of the human male reproductive system produces hormones that influence the development of male sex characteristics/
1) penis
2) testes
3) overies
4) gametes
Question #9: Fertilization usually occurs within
