ATI TEAS 7 SCIENCE WITH OVER 100 QUESTIONS
WITH UPDATED ANSWERS
1. What are the three types of salivary glands & where are they
located? (Match the letter to the number.)
A) Parotid
B) Sublingual
C) Submandibular
1) Under the jawbone
2) Roof of the mouth
3) Within the cheeks - ANS A2) Parotid is located in the roof of
the mouth.
B3) Sublingual is within the cheeks.
C1) Submandibular is under the jawbone.
2. Which of the following substances is excreted by the kidneys
to regulate blood pressure?
A) Renin
B) Erythropoietin
C) Calcitriol
D) Urobilinogen - ANS A) Renin
3. What is the chemical formula for water?
A) H₂O
,B) CO₂
C) NaCl
D) C₆H₁₂O₆ - ANS A) H₂O
4. What is the largest organ in the human body by surface
area?
A) Brain
B) Heart
C) Liver
D) Skin - ANS D) Skin
5. Which of the following units is used to indicate length?
A) kg
B) L
C) s
D) m - ANS D) m
6. The unit used to indicate length is the meter (m). It is the
base unit of length in the International System of Units (SI).
A researcher collects data on the number of cars passing through
a busy intersection at different times of the day for a month. This
data would be most useful to analyze which of the following:
A) Traffic patterns during rush hour
B) Pedestrian movement during the day
C) Air pollution levels in the area
C) Noise levels in the area - ANS A) Traffic patterns during rush
hour
7. Which of the following describes the function of ligaments?
A) Ligaments attach skeletal muscles to bone
,B) Ligaments attach two bones
C) Ligaments attach bones to tendons
D) Ligaments attach skeletal muscles to tendons - ANS B)
Ligaments attach two bones
8. Which of the following is responsible for carrying amino
acids to ribosomes during protein synthesis?
A) tRNA
B) mRNA
C) rRNA
D) DNA - ANS A) tRNA
Each tRNA molecule has a specific anticodon that matches a
codon on the mRNA molecule. When bonded, it brings the
corresponding amino acid to the ribosome, where it is added to
the growing polypeptide chain.
9. Which part of the respiratory system is responsible for
regulating breathing rate & depth?
A) Bronchi
B) Alveoli
C) Diaphragm
D) Trachea - ANS C) Diaphragm
10. Which of the following is the process by which DNA is
copied into RNA?
A) Replication
B) Transcription
C) Translation
D) Mutation - ANS B) Transcription
, During transcription, DNA unwinds & RNA polymerase reads the
DNA sequences & synthesizes a complementary RNA molecule
using DNA as a template.
11. What is the difference between innate & adaptive
immunity?
A) Innate immunity is present at birth while adaptive immunity is
acquired after exposure to pathogens.
B) Innate immunity is specific to particular pathogens while
adaptive immunity is nonspecific.
C) Innate immunity is mediated by antibodies while adaptive
immunity is mediated by T cells.
D) Innate immunity provides long-term protection while adaptive
immunity provides only short-term protection. - ANS A) Innate
immunity is present at birth while adaptive immunity is acquired
after exposure to pathogens.
Innate immunity is the first line of defense & present at birth, it
includes physical/chemical barriers. (Skin, mucous membranes,
antimicrobial peptides, macrophages, natural killer cells).
Adaptive immunity is acquired after exposure to pathogens, it
involves production of antibodies & activation of T cells specific to
particular pathogens. It's longer to develop but more
specific/targeted.
12. What are the steps involved in the scientific method?
A) Observation, hypothesis, prediction, experimentation, analysis,
conclusion.
B) Hypothesis, observation, prediction, experimentation, analysis,
conclusion.
C) Prediction, observation, experimentation, analysis, conclusion,
hypothesis.
