Which statement best describes what will most likely happen if the amphipod population is removed from this food web? Population sizes of species at feeding levels after amphipods will decrease and before amphipods will increase.
Which statement best explains how each of the different cell types?
Which statement best explains how each of the different cell types can develop from the same embryo? The cells have identical genetic instructions, but different parts of these instructions are being expressed in each cell.
What produces chemicals that regulate the reproductive cycle?
The male and female reproductive cycles are controlled by hormones released from the hypothalamus and anterior pituitary as well as hormones from reproductive tissues and organs. The hypothalamus monitors the need for the FSH and LH hormones made and released from the anterior pituitary.

Which statement best explains the fact that some identical twins?

Which disorder could develop in the human body when the immune system attacks a usually harmless environmental substance?
Allergies are the result of your immune system’s response to a substance. Immune responses can be mild, from coughing and a runny nose, to a life-threatening reaction know as anaphylaxis. A person becomes allergic when their body develops antigens against a substance.
What life function is not necessary for an individual to stay alive?

What hormones control and regulate the proper functioning of the female reproductive system?
Follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone have major roles in regulating the functions of the female reproductive system.
What cells of the immune system will help the body respond more quickly if the infectious agent is encountered again?
What cells of the immune system will help the body respond more quickly if the infectious agent is encountered again? Macrophages release pyrogens which cause body temperature to increase.
Are identical twins a hereditary trait?
Having identical twins is not genetic. On the other hand, fraternal twins can run in families. Genetics can definitely play a role in having fraternal twins. For example, a woman that has a sibling that is a fraternal twin is 2.5 times more likely to have twins than average!
