Avirtual field trip is a web search of a location you are unable to visit in person. for this virtual trip, pick any sea, lake, bay, or river in the world and research the biotic and abiotic factors that make it unique. include the following features in your virtual field trip research:

the location of your body of water
a description of the geography surrounding your body of water
the effects of sunlight on the aquatic life inhabiting your body of water
the depths and salinity of your body of water and how this shapes the types of aquatic life present
the effects of seasonal changes to water temperatures and aquatic life in your body of water
predictions or current research on the effects of climate change to your body of water

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
