TEAS 7 Science
Which of the following organelles is responsible for modifying, sorting, and
packaging
proteins and lipids? correct answers Golgi
apparatus
How do neurons communicate with each other? correct answers Through
electrical and
chemical
signals.
Which of the following structures in the nephron is responsible for
reabsorbing
water, ions,
and nutrients? correct answers Proximal
tubule
What is the function of the neuromuscular junction? correct answers
To connect
muscle fibers to motor
neurons
Explanatio
n:
The neuromuscular junction is a type of synapse where neuronal signals
from
or the brain
spinal cord interact with skeletal muscle fibers causing them to
contract.
The activation of many muscle fibers together causes muscles to contract,
which
can in turn
produce
movement.
During the menstrual cycle, which structure in the ovary produces
progesterone
prepare and
the endometrium for potential implantation? correct answers
Corpus luteum
What is the normal flora? correct answers A variety of microbial
species areas
certain foundof inthe human
body.
Which gland, located in the mediastinum, plays a key role in the
development
maturation of and
T-lymphocytes? correct answers
Thymus
Explanatio
n:
This is located and the bottom of the
bronchus.
Which of the following statements about bacteria and archaea is true?
correct answers
Bacteria can perform photosynthesis while archaea
cannot.
A patient with chronic renal failure is undergoing
hemodialysis.
What process allows for the removal of waste products and excess
fluid frombloodstream
patient's the during hemodialysis? correct answers
Diffusion
Which type of bond is responsible for the unique properties of water and
playsinathe
role crucial
structure of DNA and proteins? correct answers
Hydrogen Bonds
, What is the relationship between atomic mass and mass number?
correct mass
Atomic answers is very close to mass number but with some deviation in
the decimal
place
.
Explanatio
n:
Atomic mass is also known as atomic weight and is the weighted average
mass of an element based on the relative natural abundance of that
atom
element's isotopes.
The mass number, on the other hand, is a count of the total number of
protons and
neutrons in an atom's
nucleus.
In which type of tissue would you find a fibrous protein that provides
strength and
protection to the body, particularly in the skin, hair, and nails? correct
answers Keratin
Which of the following is true regarding the role of oncogenes in cancer
development?
correct answers Genes that regulate cell division can become
oncogenes when
mutate
d.
Which subatomic particle contributes to the positive charge of an
atom? correct
answers
Proton

the following
electrolyte imbalances? correct answers Increase in the concentration of
potassium in
the
blood.
Which of the following is a consequence of increased viscosity of a
fluid?
answerscorrect
Particles have a decrease in
mobility.
Which of the following represents the first line of defense to an intruding
correct answers Innate
pathogen?
immunity
Which organ in the human body is responsible for the removal of damaged
red blood
cells and the production of certain types of white blood cells? correct
answers Spleen
What is the largest vein in the body that returns deoxygenated blood from
thethe
of upper
bodyhalfto the right atrium of the heart? correct answers Superior
Vena Cava
Which of the following allows a limited range of immune cells to detect
and respond
rapidly to a wide range of pathogens that share common structures?
