C) In conjugation a bacterium forms a small hollow tube called a pilus. D) In conjugation a bacterium attaches to a neighboring bacterial cell that lacks a fertility plasmid.

GE produces 2 different sizes of TVs and uses 5 machines in its production. Different sizes of TVs take different amount of time to get processed at each machine, and bring in different amount of profit per unit for the company. GE has a limited amount of time to use each machine during each month but would like to find out how many of each size of TV to produce each month to maximize its total profit. How many decision...

Stan Carter is a 19-year-old male who presents to the STD clinic because he's had a sore on his penis for one week. Last sexual exposure was three weeks prior, without a condom. No history of recent travel. Predominantly female partners (three in the last six months), and occasional male partners (two in the past year). Last HIV antibody test (two months prior) was negative. Reports three children with two different women 1. Physical Exam No oral, perianal, or extra-genital...

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
