Answer:
It requires energy
Explanation:
In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.

Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
