Answer:
A nurse observes a few small, yellow nodules on the cervix of a client during the speculum exam. They are not painful or odorous, and a thin, clear discharge is present. The nurse recognizes that these are most indicative of nabothian cysts.
Explanation:
Nabothian cysts or nabothian follicles are also called mucinous retention cysts or epithelial cysts. It is a mucus-filled cyst on the surface of the cervix. Many women have multiple cysts they are common, benign and considered a normal feature of the adult cervix. They may be translucent or opaque, whitish to yellow, and range from a few millimeters to 3 to 4 cm in diameter. They are most often caused when stratified squamous epithelium of the ectocervix which is the nearest portion to the vagina that grows over the simple columnar epithelium of the endocervix which is the nearest portion to the uterus.
There are no serious complications or threat to your health with nabothian cysts.
Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
<h2>b) option is correct </h2>
Explanation:
- Some bacterial toxins cause disease by altering the activity of G protein, cholera toxin is one of them
- Cholera toxin catalyse ADP ribosylation of Gs and blocks GTPase activity thus Gs GTP become permanently active
- Constitutive activation of Gs protein continuously induce adenylyl cyclase, cytosolic cAMP level rises that leads to activation of protein kinase A (pKA)
- Activated pKA catalyse phosphorylation of two transmembrane proteins of intestinal epithelial cells:
- CFTR cause excessive outflow of Cl- ion and Na+ H+ exchange cause efflux of Na+ ion, both enters in gut and form Na+ Cl-
- Na+Cl- leads to outflow of water from the gut, resulting in diarrhea and dehydration and this condition may cause death of organisms due to loss of water and ions
Answer:
The force of gravity can cause erosion by;
- pulling rocks and other particles down the side of a mountain or cliff
- it can cause landslides which significantly erode an area.
