Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown.
Which cell that was viewed is most likely a prokaryote?
Cell W
Cell X
Cell Y
Cell Z
In a study of physical endurance, researchers observed significant increases in the heart rates and breathing rates of participants immediately after they engaged in strenuous exercise. Which statement best explains the increase in the heart rate and the breathing rate during exercise?
water concentration in the blood increases
blood cells require increase oxygen as energy is expended
muscle cells increase in temperature and require fluid to reduce temperature
an increase in muscle activity causes increases in glucose levels in red blood cells
You are told that the cells on a microscope slide are plant, animal, or bacterial. You look at them through a microscope and see cell walls and membrane-bound organelles. How should these cells be classified?
plant cells
animal cells
They could be plant cells or bacterial cells.

A human cell such as a red blood cell.
Which of the following is a major difference between a prokaryote and a eukaryote?
The need for nutrients.
The presence of a nucleus.
The presence of a cell membrane.
The presence of DNA.

cell (plasma) membrane
Golgi apparatus
mitochondrion
endoplasmic reticulum
When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell. What will be the likely consequence for the cell?
Other organelles will assume lysosome functions.
The cell will produce more ER.
The cell will undergo division.
The cell will die due to internal damage.

A prokaryotic cell has which of the following?
Centrioles
Lysosomes
Plasma membrane
Mitochondria
Mitochondria are found in most eukaryotic cells and contain their own DNA and ribosomes that are similar to those typical of many prokaryotic cells. Which of the following statements is justified by these observations?
The mitochondrion is the only location in which eukaryotic cells can synthesize ATP.
An ancestral cell most likely engulfed anaerobic prokaryote in a relationship that proved beneficial for both cells.
Mitochondrial membranes provide abundant surface area for reactions because of the infoldings called cristae.
The mitochondrion plays a role in respiration, but it also stores the cell’s extra mRNA.
The muscle cells shown above require large amounts of energy. A muscle cell might contain large numbers of -
chromosomes
vacuoles
mitochondria
lysosomes
Why is the sensation of thirst important to maintaining homeostasis?
Water removed by the kidneys must be replaced
Oxygen cannot diffuse into cells if a person is dehydrated
Water molecules are needed to carry carbon dioxide waste to the kidneys
Why is the sensation of thirst important to maintaining homeostasis?
Water removed by the kidneys must be replaced
Oxygen cannot diffuse into cells if a person is dehydrated
Water molecules are needed to carry carbon dioxide waste to the kidneys
Why does pulse rate increase during exercise?
Oxygen and carbon dioxide must be removed from the body ASAP
Gas exchange must happen more quickly than when a person is at rest
Oxygen must be moved to the lungs and carbon dioxide must be moved to cells more quickly
Carbon dioxide must be moved to the kidneys to be excreted
