Sally is a 43-year-old mother of two who has gained 50 pounds over the past 5 years. she is 64 inches tall and weighs 180 pounds with a bmi of 30.8. her waist circumference is 37 inches. she acknowledges that she is not as physically active as she would like to be. she also notes how recent stresses in her life have affected her sleep and seem to have triggered her appetite for sweets and comfort foods. sally's father recently died from complications of type 2 diabetes, and her mother and sisters are overweight. sally says she is very motivated to "not get diabetes" and is disturbed that her recent physical exam revealed mildly elevated blood pressure, glucose, and cholesterol levels. 1. sally stated that recent stresses in her life are affecting her sleep and seemed to have triggered her appetite for sweets and comfort foods. which of the following statements would be best to explain why her lack of sleep has increased her appetite? a. lack of sleep decreases ghrelin levels. b. levels of neuropeptide y, a brain chemical that causes carbohydrate cravings, are high and may contribute to her sleep problems. c. the satiety hormone leptin increases with lack of sleep. d. lack of sleep increases uncoupling protein. e. lack of sleep increases levels of ghrelin which stimulates appetite and decreases levels of leptin which decreases appetite.

The herpes viruses are important enveloped dna viruses that cause disease in vertebrates and in some invertebrates such as oysters. some of the human forms are herpes simplex virus (hsv) types i and ii, causing facial and genital lesions, and the varicella zoster virus (vsv), causing chicken pox and shingles. each of these three actively infects nervous tissue. primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. the virus can later reactivate, replicate again, and infect others.in electron micrographs of hsv infection, it can be seen that the intact virus initially reacts with cell surface proteoglycans, then with specific receptors. this is later followed by viral capsids docking with nuclear pores. afterward, the capsids go from being full to being "empty." which of the following best fits these observations? a) viral capsids are needed for the cell to become infected; only the capsids enter the nucleus.b) the viral envelope is not required for infectivity, since the envelope does not enter the nucleus.c) only the genetic material of the virus is involved in the cell's infectivity, and is injected like the genome of a phage.d) the viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus.
