An enzyme that can bind to and break apart molecules of lactose should also be able to bind: a. fatty acids. b. amino acids. c.
Airida [17]

Answer: Option E) None of the above is true; this enzyme could bind none of these.

Explanation:

Lactose is a dissacharide composed of glucose and galactose. Hence, the enzyme lactase break down lactose into its simple sugar constituents.

However, lactase cannot bind nor break down amino acids, starch (with only glucose units) or sucrose (with two glucose units) because their constituent molecules differ markedly from that of lactose.

Thus, the enzyme lactase could bind with none of the options provided except lactose

Breeding programs and habitat preserves have been established as an effort to protect the florida panther from extinction. studi
Inessa05 [86]
The answer is ‘panthers will become extinct due to the lack of genetic diversity’. The population will enter what is referred to an extinction vortex. This is when environmental, demographic and genetic factors interact and reinforce each other in a downward spiral of a species. The lack of genetic diversity in the population causes inbreeding and lack of diversity on which natural selection can act upon for the population to adapt.
