Unit 5 Reproduction and Development Review

Identify a body system that affects a falcon's ability to nest eggs.

Folic acid is a type of vitamin that is essential for the normal growth and development of cells in the body. If a woman consumes folic acid in her diet before and during the earliest stages of pregnancy, it can help to reduce her baby's risk for developing a type of birth defect called a neural tube defect. Early in pregnancy, the neural tube forms the brain and spinal cord. If the neural tube does not form properly, serious birth defects may result.

Identify the organ formed from the neural tube that may be defected by the lack of folic acid.

Identify the organ that facilitates a fetus receiving folic acid and other essential materials directly from its mother for its development.

Identify one factor, other than a lack of folic acid, that may interfere with the proper development of essential organs during pregnancy

The human female reproductive system is represented below. Within which structure does the placenta normally develop?

• A

• B

• C

• D

Identify the structure within which the egg cell is produced.

• A

• B

• C

• D

The diagram below represents one stage during the human reproductive process. A function of structure A is to

• remove nutrients from the fetus

• provide the fetus with metabolic wastes

• remove all toxins from the blood of the mother

• provide for the exchange of oxygen and carbon dioxide

Identify the type of cell division involved in this process. Production of Skin Cells:

• Mitotic cell division

• Meiotic cell division

Identify the type of cell division involved in this process. Production of Gametes:

• Mitotic cell division

• Meiotic cell division

The diagram below represents a form of cellular reproduction. As a result of this process, offspring 1 and offspring 2 will have

• a different number of genes but the same traits

• the same number of genes and the same traits

• a different number of genes and different traits

• the same number of genes but different traits
