HESI A2 V2 BIOLOGY Exam Questions with Correct
Solutions| 100% verified 2025-2026 Rated A+
A patient receives an antibiotic for symptoms of the flu. Why
doesn’t the medication work?
The medication is for a different type of flu.
The medication is not suitable for treating the flu.
The medication is not a strong enough dosage amount to
cure the
patient.
None of the above
The correct answer is B. Antibiotics are used for treating
bacterial
infections, but the flu is caused by a virus. Although
symptoms can
be similar in case of a cold (bacteria) or the flu (virus), viruses
cannot be treated using antibiotics.
The nucleus is important in a cell because:
It stores the DNA
It supports the cell
It makes protein
It makes energy out of food
,The correct answer is A. The nucleus is the “brain” of the cell
and
stores the DNA. A cell wall supports the cell (only if it is a
plant).
The ribosomes make protein and the mitochondria makes
energy.
Cellular respiration happens so that
Cells can copy DNA
Cells can breathe
Cells can convert nutrients to energy
Cells can divide
The correct answer is C. The term respiration typically
triggers
thoughts of breathing, but in this case, it is referring to the
process
about:blank 2/31
cells undergo to convert nutrients into ATP. Copying DNA is
transcription and translation. Cells themselves cannot
breathe. Cell
division is mitosis or meiosis, depending on the type of cell.
Anaerobic respiration
happens in
Animals; they need energy
Plants; they use sunlight
_ because _ .
Bacteria; they live in environments with low oxygen.
None of the above
The correct answer is C. Animals and plants both use aerobic
respiration because they have access to oxygen. Bacteria
, typically
live in environments with little to no oxygen and must still
produce
energy to survive.
