47. find the mismatched pair: a)facilitated diffusion extrusion of ions or small molecule with expense of ar b) uniport-a single molecule or ion passes through a carrier, regardless of direction (in or out) c) antiport_type of coupled transport in which one solute enters, another one exits the cell d)symport--type of coupled transport in which two solutes simultaneously enter or exit the cell.

Option (A).

Explanation:

Facilitated diffusion may be defined as the process of  movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.

Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.

Thus, the mismatched pair is option (A).

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

i think the miocene epoch spans the time from 23 million to 12 million years ago.
