PRACTICE QUESTIONS AND ANSWERS
Which of the following organelles is responsible for modifying, sorting, and packaging
proteins and lipids? Golgi apparatus
How do neurons communicate with each other?
Through electrical and chemical signals.
Which of the following structures in the nephron is responsible for reabsorbing
ions, water, and nutrients? Proximal tubule
What is the function of the neuromuscular junction?
To connect muscle fibers to motor neurons Explanation:
The neuromuscular junction is a type of synapse where neuronal signals from the brain or
spinal cord interact with skeletal muscle fibers causing them to contract.
The activation of many muscle fibers together causes muscles to contract, which in turn can
produce movement.
During the menstrual cycle, which structure in the ovary produces progesterone and prepare
the endometrium for potential implantation? Corpus luteum
What is the normal flora?
A variety of microbial species found in certain areas of the human body.
Which gland, located in the mediastinum, plays a key role in the development and maturation
of T-lymphocytes?
Thymus
Explanation:
This is located and the bottom of the bronchus.

PRACTICE QUESTIONS AND ANSWERS
Which of the following statements about bacteria and archaea is true?
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 from the patient's
bloodstream during hemodialysis? Diffusion
Which type of bond is responsible for the unique properties of water and plays a crucial
role in the structure of DNA and proteins? Hydrogen Bonds
What is the relationship between atomic mass and mass number?
Atomic mass is very close to mass number but with some deviation in the decimal place.
Explanation:
Atomic mass is also known as atomic weight and is the weighted average mass of an atom of
an element based on the relative natural abundance of that 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?
Keratin
Which of the following is true regarding the role of oncogenes in cancer development?
Genes that regulate cell division can become oncogenes when mutated.
Which subatomic particle contributes to the positive charge of an atom? Proton

Which of the following is a consequence of increased viscosity of a fluid?
Particles have a decrease in mobility.
Which of the following represents the first line of defense to an intruding pathogen?
Innate 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? Spleen
What is the largest vein in the body that returns deoxygenated blood from the upper half of
the body to the right atrium of the heart?
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?
Pattern recognition receptors
Which hormone is responsible for the development of female secondary sexual
characteristics such as breast development, menstrual cycle, and widening of hips?
Estrogen

A patient with a history of heart failure is prescribed a medication that increases urine output
to reduce fluid buildup.
Which of the following statements best describes the mechanism of action of the prescribed
medication?
Enhances glomerular filtration rate
What is the hallmark of adaptive immunity?
Immunologic memory
Which of the following hormones is responsible for regulating the body's metabolism and
energy levels? Thyroxine
Explanation:
Thyroxine (T4) is a hormone produced by the thyroid gland and controls the body's
metabolism.
Which of the following refers to a condition in which a patient experiences difÏculty
breathing while lying down, but their breathing improves when they sit up or stand?
Orthopnea
What is the function of inflammatory cytokines released during the early response to
bacterial infection?
Initiating cell recruitment and local inflammation.
