Sperm are produced in the A. epididymis; testes B. ductus deferens; epididymis C. seminiferous tubules; pro D. seminiferous tubules; epididymis E. seminiferous tubules; vas deferens state glandExplanation / Answer
90) a. Have long loops of Henle.
Juxta = near and medullary = renal medulla. This indicates that the renal corpuscles of these neurons are located in close proximity of the medulla. As a result of which the convoluted tubule and the loop if Henle need to go deep in order to reach the cortex and hence are longer. They form only 20-30% of the total nephrons.
91) c. Provides a temperature that is suitable for normal development.
Sperms require 2-3 degrees cooler temperature than the body temperature for proper development.
92) a. Scrotal sac.
Because it is located outside the body (abdominal cavity) and has a temperature 2-3 degrees lower than the normal body temperature).
93) c. Seminiferous tubules
