Answer:
Nucleus and acrosome
Explanation:
Human sperm is the male gamete or sex cell formed by spermatogenesis. It is made of a head, neck, a middle piece and a tail. The sperm head consists of a haploid nucleus and anterior to nucleus, an acrosome. The nucleus contains DNA and nuclear protein and it transfers genetic features from the male to the next generation. The acrosome contains an important enzymes, hyaluronidase and acrosin. These enzymes help to enter head into an ovum.

Answer:
It will plateau and the population will stabilize in relationship to available resources.
Explanation:
Having an unhinged rabbit population with no predators and an abundance of food will cause the population to initially increase. This increase will be due to an environment free from predation and also encouraged by an abundance of food.
In time these rabbits will increase in number and will put a strain on food supply. Dwindling resources will put pressure on reproduction. In addition to this these have a limited gene pool since they have been only reproducing with each other. This will pass along any disease sensitivity that they may have. In the even that a disease is introduced into the population many of them will be wiped out.
In conclusion, without a constant food supply to support a growing population the rabbit population will not multiply exponentially, indefinitely.
Answer:
D.) Rocky

The crust is the top layer of the Earth which is relatively thin in comparison to other layers. The upper layer of Earth is called lithosphere.
The crust is composed of variety of rocks such as metamorphic, igneous, and sedimentary rocks. Below the crust, is the mantle which is also composed of rocks but also have semi-solid magma.
