QUESTIONS AND CORRECT VERIFIED
ANSWERS| WELL GRADED A+
Which is the best example of active transport? - CORRECT ANSWERS-Movement
requiring the expenditure of metabolic energy
Active transport requires a life, biologic activity, and the expenditure of metabolic
energy. Movement due simply to differences in concentration gradients is called passive
transport. Movement of two molecules in the same direction is called symport, while
moving two molecules in opposite directions is called antiport.
Which method of transport uses transmembrane proteins with receptors with a high
degree of specificity for the substance being transported? - CORRECT ANSWERS-
Mediated
Mediated transport(passive and active) involves integral or transmembrane proteins
with receptors having a high degree of specificity for the substance being transported.
Active and passive transport are opposites with active transport requiring the use of
energy and passive transport relying on osmosis, hydrostatic pressure, and diffusion
and not energy. Transmembranous means "across membranes."
Which structure prevents water-soluble molecules from entering cells across the plasma
membrane? - CORRECT ANSWERS-Lipid bilayer
The bilayer's structure accounts for one of the essential functions of the plasma
membrane. It is impermeable to most water-soluble molecules (molecules that dissolve
in water) because the water-soluble molecules are insoluble in the oily core region. The
bilayer serves as a barrier to the diffusion of water and hydrophilic substances while
allowing lipid-soluble molecules, such as oxygen (O2) and carbon dioxide (CO2), to
diffuse through it readily. Carbohydrate chains, glycoprotein channels, and membrane
channel proteins do not prevent water-soluble molecules from entering cells across the
cell membrane.
A healthcare professional is caring for four patients with cancer. Which patient does the
professional educate about brachytherapy? - CORRECT ANSWERS-b.Cervical
Radiation sources, such as small 125I-labeled capsules (also called seeds), can also be
temporarily placed into body cavities, a delivery method termed brachytherapy.
Brachytherapy is useful in the treatment of cervical, prostate, and head and neck
cancers. Brachytherapy is not used in the treatment of the other cancers.
, A person with 47, XXY karyotype has the genetic disorder resulting in which syndrome?
- CORRECT ANSWERS-Klinefelter
A disorder in the chromosome (47, XXY karyotype) results in a disorder known as
Klinefelter syndrome. Turner syndrome has a karyotype of 45, X. Down syndrome is
caused by Trisomy 21. Fragile X syndrome is caused by microscopically observable
breaks and gaps in the X chromosome.
Carcinoma in situ is characterized by which changes? - CORRECT ANSWERS-Cells
remain localized in the glandular or squamous cells.
Carcinoma in situ (CIS) refers to preinvasive epithelial malignant tumors of glandular or
squamous cell origin. These early stage cancers are localized to the epithelium and
have not broken through the local basement membrane or invaded the surrounding
tissue. Dysplasia refers to changes in mature cell structure.
In childhood neuroblastoma, the N-myc oncogene undergoes which type of mutation of
normal gene to oncogene? - CORRECT ANSWERS-Gene amplification
Amplifications are the result of the duplication of a small piece of a chromosome over
and over again; consequently, instead of the normal two copies of a gene, tens or even
hundreds of copies are present. The N-myc oncogene is amplified in 25% of childhood
neuroblastoma.
Regarding type 2 diabetes, obesity is considered (for most patients) what type of risk? -
CORRECT ANSWERS-Modifiable
A modifiable risk is one a person can change in order to reduce risk. Obesity is a
modifiable risk factor for many diseases including heart disease, stroke, hypertension,
and type 2 diabetes. Genetic, empirical, and relative risks are not changeable by
individuals in order to reduce their chance of developing diseases.
The BRCA1 and BRCA2 mutations increase the risk of which cancer in women? -
CORRECT ANSWERS-Ovarian
BRCA1 mutations increase the risk of ovarian cancer among women (20% to 50%
lifetime risk), and BRCA2 mutations also confer an increased risk of ovarian cancer
(10% to 20% lifetime prevalence). BRCA1 and BRCA2 mutations are not currently
believed to be linked with risks of lung, uterine, or pancreatic cancers.
The data reporting that sickle cell disease affects approximately 1 in 600 American
blacks is an example of which concept? - CORRECT ANSWERS-Prevalence
Prevalence rate is the proportion of the population affected by a disease at a specific
point in time. Thus both the incidence rate and the length of the survival period in
affected individuals determine prevalence. The incidence rate is the number of new
cases of a disease reported during a specific period (typically 1 year), divided by the
number of individuals in the population. A numerical expression representing a part of a
larger whole or proportion is considered a ratio. Any factor that increases the chance of
disease or injury is considered a risk.
The prevalence rate is the proportion of the population affected by a disease at a
specific point in time. Thus both the incidence rate and the length of the survival period
