Question 5 (Multiple Choice Worth 2 points)
(02.02 HC)  When a cell has to endure lasting changes in its environment that require it to actively transport more molecules than normal through the cell membrane,  what effect will this have on the mitochondria of the cell? The cell will need
fewer mitochondria since the transport proteins will also create ATP.
more mitochondria to meet the increased energy demand.
more mitochondria to repair damage to the ATP molecules.
fewer mitochondria since there will be fewer molecules left in the cell.
Question 6 (Multiple Choice Worth 2 points)
(02.01 HC) While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid with a ladder structure and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
The nucleic acid is RNA and would be found in the cell’s nucleus.
The nucleic acid is RNA and would be found in the cytoplasm.
The nucleic acid is DNA and would be found in the cytoplasm.
The nucleic acid is DNA and would be found in the cell’s nucleus.
Question 7 (Multiple Choice Worth 2 points)
(02.02 LC)  Which of the following is true of modern cell theory?
As technology improves so will our understanding of cells.
Multi-celled organisms are the focus of most modern discoveries.
Early cell theory has turned out to be incorrect.
Scientists have learned all they can about cells at this point.
Question 8 (Multiple Choice Worth 2 points)
(02.03 MC)  All eukaryotic cells have a cytoskeleton, including plant cells, which have cell walls as well. What does the cytoskeleton in a plant cell do that the cell wall cannot?
It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing.
It helps keep the organelles in place and directs their movement as needed.
It provides anchoring places for the cell cytoplasm and helps…
