Explanation:
because the rest are part of the DNA strand
Toxic water quality in the Klamath River is a direct result of both upper basin agricultural development (the draining of wetlands and intense chemical use), and the presence of PacifiCorp's dams, creating warm, stagnant pools for algae to develop. Massive algae pools in Upper Klamath Lake.
<u><em>Female:</em></u>
*Ovaries - release of oocytes (eggs), estrogen and progesterone.
*Oviducts (fallopian tubes) - where fertilization of the oocyte occurs to form a zygote.
*Uterus - where the zygote develops
*Cervix and vagina - allow for the entry of sperm for fertilization
<u><em>Male:</em></u>
*Testes - Releases testosterone and sperm
*Vas deferens - Passageway for sperm
*Epididymis - allows the sperm to pass from the testes and vas deferens and equips them with semen so they can survive internal fertilization
*Penis - releases sperm into the external environment for fertilization to occur
