There should be options for this question. I manged to find them elsewhere. They are:
A) the period during which tremendous growth occurs and the organs continue to develop and become functional
B) the period during which the umbilical cord develops
C) the period during which the major organs and structures of the organism first develop
D) the period during which the zygote moves down to the uterus and begins to implant in the lining
The correct answer is C. The embryonic period is the period during which the major organs and structures of the organism first develop. The embryonic period lasts from implantation of the egg in the uterus until about 8 weeks from the time of conception. It is the second major stage of prenatal development, prior to embryonic is the germinal stage and lastly is the fetal stage.

Answer:
The function of the bones in bats that are homologous to finger bones in humans is to FLY.
Explanation:
Homologous anatomy- it means that the organisms have the same anatomy or bone structure but it is used for different functions. They are evolved from a common ancestor.
human beings, bats and birds have the homologous forearms. They have the same types of bones present in their forearm but however each of them use it for different purposes. A human being uses to lift things, cook, type and other mundane things whereas a bat uses it's forearms as wings to fly.
Answer:A) The ocean is hypertonic to the erythrocytes.
Explanation:cells shrink when placed in an hypertonic solution.
This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.
The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
