Well, the food is in the environment. I would like to compare it with how bacteriae feed (however my biology is quite rusty), that is, they engulf their food and they "digest" -- not the proper term, since there are no organs to do real digestion -- it.
The correct answer is - one-half.
In the past century, the deforestation of the rainforests in the world had been devastating, and it is estimated that approximately one half of the tropical rainforests have been destroyed.
The reason for the large scale destruction of the rainforests is mainly because of clearing space for agriculture and for spaces where the cattle can graze. Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly. Because of that, people just continue to clear more and more of it, thus leaving destroyed forest and destroyed soil behind them, without taking in consideration the long term effects.

</span> All normal eggs from the mother have an X chromosome while usually half the sperm cells from the father have a Y (male) chromosome and the other half have an X (female) chromosome and it is therefore the father's sperm that dictates which gender the embryo will take.
If the egg is fertilized by a sperm with a Y chromosome then the embryo will be a genetic male due to XY chromosome combination.
<span>If the egg is fertilized by a sperm with an X chromosome then of course the embryo will be a genetic female due to XX chromosome combination.</span>
Answer:
b. did not know how to care for infants
Explanation:
Research shows that captive-bred monkeys without their mothers don't know how to care for babies. This is because these little monkeys grow up without maternal support, do not have a behavioral model about caring for babies and therefore can not create enough affective bond to care for their infants. Monkeys are very intelligent beings and often associate the behavior of other monkeys as inspiration for the situations they are facing, captive-bred monkeys without their mothers do not have this model of inspiration and therefore do not know how to take care of baby monkeys.
