The correct answer is: Both experienced the most rapid uptake of glucose at the beginning of the experiment.
The difference between pigs would be in their uptake of glucose during the whole experiment, where the younger guinea pig's cells took up more glucose than the older guinea pig's. This is because older guinea pigs have fewer glucose transporter proteins.
Answer:

Mendelian disorder is the known disorder of a single gene
Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.
