22. In a study of heart rate in ocean-diving birds, researchers harnessed 10 randomly sampled, wild-caught cormorants
to a laboratory contraption that monitored vital signs.
Each cormorant was subjected to six artificial “dives" over
the following week (one dive per day). A dive consisted of
rapidly immersing the head of the bird in water by tipping
the harness. In this way, a sample of 60 measurements of
heart rate in diving birds was obtained. Do these 60
measurements represent a random sample? Why or why not?
not?

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit.there is a precise compatibility between the active site and the lactose molecule.specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed.reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
