HESI A2 (NURSING ADMISSION TEST) CHEMISTRY
EXAM QUESTIONS WITH CORRECT ANSWERS
What |do |ribosomes |do? |- |ANS-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?
|- |ANS-Chloroplasts
Explanation:
Chloroplasts |are |found |in |plant |cells |and |contain |chlorophyll |which
|converts |the |energy |from |sunlight |into |sugars.
What |is |mitosis? |- |ANS-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 |- |ANS-cytosine |(C),
|guanine |(G), |adenine |(A), |and |thymine |(T)
If |a |genotype |consists |of |two |identical |alleles, |is |it |homozygous |or
|heterozygous? |- |ANS-homozygous
A |relationship |between |two |organisms |which |is |of |benefit |to |both, |is
|what |kind |of |symbiosis? |- |ANS-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? |-
|ANS-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.
- |ANS-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 |transports |nutrients |and |waste.
What |is |a |normal |pulse |rate |for |an |adult? |- |ANS-60 |to |100 |bpm
Where |in |the |body |would |you |find |the |alveoli |and |what |is |their |function? |-
|ANS-The |alveoli |are |found |in |the |lungs |and |facilitate |oxygen |and |carbon
|dioxide |exchange |between |the |air |in |the |lungs |and |the |blood.
Which |enzyme |is |secreted |by |the |body |to |aid |the |digestion |of |fat? |-
|ANS-lipase
Name |the |two |primary |female |sex |hormones. |- |ANS-Estrogen |and
|progesterone
Which |primary |endocrine |gland |releases |both |insulin |and |glucagon? |-
|ANS-The |pancreas
Name |the |five |types |of |bone |found |in |the |human |body. |- |ANS-Long, |flat,
|short, |sesamoid, |and |irregular
What |is |the |function |of |afferent |neurons? |- |ANS-To |send |signals |to |the
|central |nervous |system
