The countercurrent heat exchanger that prevents arterial blood from overheating the testes is the pampiniform plexus of veins. The pampiniform plexus helps to regulate testicular temperature, allowing sperm maturation. It surrounds the testicular arteries and works as a countercurrent heat-exchanger system to cool the arterial blood before entering the testes. This is because the sperms can not develop if the testis is at body temperature.
Since Mary has a Type A blood, she is either AA or AO while John is either BB or BO. Since both John's parents are Type AB, he can only have the either A or B as an allele and not O so he is BB. Since John can only give the B allele, all of his children must have the B allele in their blood types. So the adopted one is the child with type A blood.
Drip method is one of the mainstays of sustainable agriculture because it : A. reduces soil erosion
Like the name said, Drip irrigation is designed to utilize the least amount of water supply by giving the water to the plant drip by drip. In this method, there is no flow of water that commonly caused the soil erosion (because the water flow cut out the soil little by little)
