Which row in the chart correctly identifies where in the female reproductive system these two processes occur?
1
2
3

The process of embryonic development is represented in the diagram below.
The three arrows in the diagram each represent a process known as
mitotic cell division
meiotic cell division
fertilization of gamete cells
differentiation of tissues
It is recommended that children eat foods high in calcium and iron as a way to reduce the accumulation of lead in their cells and enzymes. Explain why this is a scientifically valid recommendation.
Describe how the presence of lead in body cells could interfere with the ability of enzymes to function.
Describe how the presence of lead in body cells could interfere with the ability of enzymes to function.
Explain why taking folic acid early in pregnancy is important to the prevention of neural tube defects.
Describe how a fetus receives 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.
Many foods, such as breads, cereals, pastas, and rice, are fortifi ed or enriched with folic acid. Explain why adding folic acid to foods is an advantage to people other than pregnant women.
Which statement about the functioning of the human reproductive system is correct?
The zygote helps the mother provide milk to the fetus before it is born.
Testes produce unfertilized eggs and release them so that they can be fertilized by sperm.
Ovaries are where male gametes undergo meiosis to reduce their chromosome number.
The uterus is where the fetus develops internally until birth.
Which row in the chart below contains the correct sequence of events involved in the formation of a human embryo?
1

Since the four types of cells contain the same genetic instructions, how is it possible for them to have different shapes and carry out different functions?
Each cell type has the ability to remove unnecessary DNA sequences.
Different parts of the genetic code may be used in each of the cell types.
Different gene mutations take place within each cell type.
Each cell type is the result of different methods of cell division.
The cells of the offspring would have
half the genetic information, when compared to cells of the parent plant’s leaves
the same genetic information, when compared to cells of the parent plant
twice as much genetic information as is present in the cells of the parent plant
incomplete genetic information, because the parent plant does not produce seeds
Proteins are an important part of any diet. Many kinds of food can provide the proteins that we need.
State what must happen to protein molecules in food before cells can use them.
Proteins are an important part of any diet. Many kinds of food can provide the proteins that we need.
Identify the structure in a cell where proteins are synthesized.
Proteins are an important part of any diet. Many kinds of food can provide the proteins that we need.
Identify which characteristic of a protein molecule allows it to perform a specific function.
Size
Structure
A multicellular organism has cells that perform various roles in that organism. This is most likely due to the
differentiation of cells during embryonic development
specialization of gametes
cloning of cells during embryonic development
specialization of zygotes
Based on the graph, which statement is correct regarding the interaction of the levels of estrogen and progesterone?
When the amounts of estrogen and progesterone are at the same level, an egg begins to develop in the ovary.
When an egg is released from the ovary, the level of estrogen is higher than the level of progesterone.
The level of progesterone controls the cycle since it is always higher than the level of estrogen.
After an egg is released from the ovary, the level of estrogen keeps increasing, causing the level of progesterone to decrease.
In order to observe whether or not this root tip was growing, the student should
switch to a higher magnification and look for evidence of cell division
switch to a lower magnification and look for evidence of cell division
switch to a lower magnification and add a stain to the onion root tip cells
switch to a higher magnification and add salt solution to the onion root tip cells
Identify when during Earth’s history autotrophs most likely first appeared. Support your answer using information from the graph.
2500 because that is when the oxygen level began to increase
2500 because that is when the carbon dioxide level began to increase
Present Day because that is when the oxygen level evened out
2500 because that is when the carbon dioxide level began to increase
Identify an organ of the human body where diffusion occurs, and identify one specific molecule that diffuses between that organ and the blood.
In humans, embryonic development during the first two months is more sensitive to environmental factors than during the remaining months. The best explanation for this statement is that
during the first two months, organs are being formed and any unusual change during cell division can interfere with normal development
the genes that control development function only during the first two months of development
no changes occur in a developing fetus after the second month
organ development is not affected by environmental factors after the second month
