<span>During digestion, the blood picks up nutrients absorbed through the gi tract and transports them to the <u>different organ systems of the body.</u> The oxygen and nutrient-rich blood can be transported throughout the body by the different blood vessels that surround it. Without blood circulating through the body, it would be hard for the body to maintain its homeostasis and survive for long.</span>
<h2>Ovulation</h2>
Explanation:
Women are born with approximately one to two million ova while female fetuses actually have far more egg cells when they are in the mother’s womb—sometimes as many as six or seven million eggs
- When egg cells are immature they are referred to as oocytes
- By the time a woman reaches puberty, there are only a small fraction of oocytes left—usually about 300,000
- During the reproductive lifespan, only about 500 of a woman’s eggs are ovulated
- The remaining eggs that are left behind die out during menopause
- Egg death is a natural part of the cycle of the female reproductive system so prior to menopause, women typically lose a thousand or so eggs every month
C) A is probably much more closely related to B than to C.
Because A/B have 95% DNA in common, but A/C only have 50% in common.
in an ecosystem, fungi play the role of decomposers -- they break down dead organic matter and return vital nutrients to the soil. Without fungi, nutrients would not cycle through an ecosystem, causing the breakdown of the entire food chain.
hope this helps :)
