HESI A2 Biology practice reviews cell structure, genetics, and basic biological processes that underlie later physiology coursework.
The soft spots on the head of a newborn are called ______?
Which gas is crucial for the survival of most life forms and is released during photosynthesis?
Glycolysis is one of the body's chemical pathways for which of the following?
The head of a newborn has a soft spot near the crown. What is the medical term for this soft spot?
What is a major difference in the way baroreceptors and chemoreceptors work compared to the way the kidneys work in regulating blood pressure?
Which term indicates a sudden disturbance in the body's equilibrium due to system failure or fluid loss?
Aerobic respiration occurs in the presence of what necessary molecule?
The movement of a substance across a cell membrane from an area of low concentration to an area of high concentration is known as what?
In a certain plant, the dominant allele R produces bright-red seeds, and the recessive allele r produces pale-pink seeds. A scientist crosses a true-breeding RR plant with a true-breeding rr plant to produce the F1 generation. The F1 plants are then crossed with each other (self-crossed) to produce the F2 generation. What percentage of the F2 plants will have bright-red seeds?
What is the first step in the process of cellular respiration?
A cell is placed in a solution in which the concentration of solutes is higher inside the cell than outside the cell (i.e., a hypotonic solution surrounds the cell). What would you expect to happen to the cell?
If bacteria are placed in a strong solution of salt water, they will shrink as water moves out of the bacterial cell. What is this process called?
Once you're comfortable with biology, try a full HESI A2 practice test to see how it holds up under timed, mixed-section conditions, or head back to all HESI A2 categories.
