1. What term refers to "the occurrence of death from a condition in a
population?"
Mortality
Epidemiology
Prevalence
Morbidity
2. What is one of the primary functions of the smooth endoplasmic reticulum
(ER)?
Lipid synthesis
Cell division
DNA replication
Protein synthesis
3. What is the primary role of a cell in living organisms?
To perform essential life processes
To facilitate digestion
To produce hormones
To store genetic information
4. What are the main components of a typical eukaryotic cell?
Nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus,
plasma membrane
, Mitochondria, ribosomes, cell membrane, cytoplasm, lysosomes
Cell wall, chloroplasts, ribosomes, lysosomes, cytoplasm
Nucleus, chloroplasts, vacuoles, cytoplasm, plasma membrane
5. A diagnostic test is said to be highly SENSITIVE when it is capable of:
Correctly classifying individuals without the condition of interest (true
negatives)
Promoting a big in shift in probability of having the condition when the
test result is positive
Correctly classifying individuals with the condition of interest (true
positives)
Correctly Rule IN the condition
6. What does specificity measure in diagnostic testing?
The likelihood of a false positive result.
The ability of a test to correctly identify those without the disease.
The overall accuracy of a test.
The ability of a test to correctly identify those with the disease.
7. Describe the role of mitochondria in cellular metabolism.
Mitochondria synthesize proteins for the cell.
Mitochondria store genetic information.
Mitochondria regulate cell division.
Mitochondria convert nutrients into energy through the process of
cellular respiration.
,8. The best example of secondary prevention would be:
Removing hazards that may cause accidents
Administering immunisations
Providing rehabilitation for stroke victims
Treatment of women following an abnormal pap smear
9. The term morbidity refers to
high risk behaviors.
the process of death
the incidence of unhealthy patterns.
illness and disease.
10. If a drug targets G-Protein-Linked Receptors, what potential effect could it
have on cellular communication?
It could lead to uncontrolled cell division.
It could enhance or inhibit the transmission of signals within the
cell.
It could prevent the uptake of nutrients.
It could increase the rate of protein synthesis.
11. A good diagnostic test needs to be reliable and valid. reliability refers to...
accuracy
consistency
the reference "gold" standard
, 12. The function of smooth endoplasmic reticulum (ER) includes:
D. Produce ATP
A. Breakdown (detoxification) of drugs
B. Storage and release of Ca++
E. Both A and B
C. Synthesis of proteins
13. Describe how hyperplasia differs from hypertrophy in terms of cellular
changes.
Hyperplasia is a form of cell death, while hypertrophy is an increase
in cell number.
Both hyperplasia and hypertrophy involve an increase in cell size.
Hyperplasia involves an increase in cell number, while hypertrophy
involves an increase in cell size.
Hyperplasia and hypertrophy are synonymous terms.
14. What are the two processes encompassed by endocytosis?
Exocytosis and transcytosis
Osmosis and diffusion
Active transport and facilitated diffusion
Phagocytosis and pinocytosis
15. Describe the significance of mortality in the study of epidemiology.
Mortality measures the number of new cases of a disease in a
population.
