Answer:

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.

In general, locomotion on land will require more energy than locomotion in water. By integrating what you learned about animal f

denis-greek [22]

Answer:

Land animals require more energy since they have to overcome greater inertia during locomotion. Land mammals have adopted many evolutionary mechanisms to support high energy demand.

Heart is four chambered instead of the usual two in aquatic animals like fishes. More number of divisions in heart increases the efficiency of blood circulation process which in turn increases the oxygen delivery rate to cells for producing more energy.

Land mammals also have developed lungs which increase the efficiency of gas exchange process which increases the output of respiration process.

In addition, land mammals also have a strong and developed musculoskeletal system which helps in locomotion.

What is a phenotypic ratio

almond37 [142]

Phenotypic ratio is comparing the number of dominant genes to the number of recessive genes

so like let's say there are 3 dominant genes and 1 recessive, you'd write the ratio like this

3:1

Adult giraffes eat about 75 pounds of food in a day. On average, an area can provide 450 pounds of food per day for giraffes. Ba

densk [106]

Answer:

6 giraffes

Explanation:

If an area can provide 450 pounds of food for the giraffes and the giraffes eat 75 pounds of food per day, you can divide:

450 by 75= 6

6 giraffes is the capacity for that area
