HESI A2 (NURSING ADMISSION
TEST)2026 CHEMISTRY
What do ribosomes do? - CORRECT ANSWERS -Build proteins from amino acids
Explanation:
Ribosomes are molecules which create proteins by linking amino acids together
in a particular order, using messenger RNA molecules as a blueprint.
What is the name of the organelle(s) where photosynthesis takes
place? - CORRECT
ANSWERS -
Chloroplasts
Explanation:
Chloroplasts are found in plant cells and contain chlorophyll which converts the
energy from sunlight into sugars.
What is mitosis? - CORRECT ANSWERS -The division of a cell nucleus.
Explanation:
During mitosis, a cell nucleus divides, producing two identical sets of
chromosomes.
Name the four primary nucleobases found in DNA - CORRECT ANSWERS -
cytosine (C),
guanine (G), adenine (A), and thymine (T)
If a genotype consists of two identical alleles, is it homozygous or
heterozygous? - CORRECT
ANSWERS -
homozygous
,A relationship between two organisms which is of benefit to both, is
what kind of symbiosis? - CORRECT ANSWERS
-Mutualism.
e.g. the relationship between clownfish and sea anemones - the clownfish clean
and feed the sea anemones, while the sea anemones protect the clownfish from
predators.
In taxonomy, which ranking is most inclusive, Kingdom or Genus? -
CORRECT
ANSWERS -
Kingdom
Explanation:
Kingdom is the second highest rank, containing Animalia, Plantae, Fungi,
Protista, Archaea and Bacteria. Genus comes below Family and above Species.
, Name the two circuits through which blood travels in the human body.
- CORRECT ANSWERS -
Pulmonary and
systemic
Explanation:
The pulmonary circuit carries blood to the lungs to be oxygenated. The systemic
circuit delivers this oxygenated blood to the rest of the body and trCORRECT
ANSWERS ports nutrients and waste.
What is a normal pulse rate for an adult? - CORRECT ANSWERS -60 to 100 bpm
Where in the body would you find the alveoli and what is their function? -
CORRECT ANSWERS -The alveoli are found in the lungs and facilitate oxygen
and carbon dioxide exchange between the air in the lungs and the blood.
