[Answer] What determines the sex of newborn alligators?

Step 1 : Introduction to the question "What determines the sex of newborn alligators?"

...Temperature is the deciding factor in an alligator`s gender, according to Dr. Paul Cardeilhac, a professor of veterinary medicine at the University of Florida. Alligators and some turtles are known to display temperature-dependent sex determination (TSD), where the temperature of the environment in which the eggs are raised in determines the sex of the individual. For example in the alligator's eggs, incubation at 34ºC and above produces mostly males, while incubation at 30ºC and below produces mostly females.

[Ans] Which flavor are newborn babies unable to taste?

Step 1 : Introduction to the question "Which flavor are newborn babies unable to taste?"

Human taste buds are capable of detecting and distinguishing tastes in five categories: sweetness, bitterness, sourness, saltiness and umami, which is a hearty, savory taste found in meats, mushrooms and milk products. Newborns, however, can't distinguish the taste of salt until they reach about four months old. As any mother can attest, newborns show a distinct preference for foods and liquids with a sweet taste almost immediately. Recent studies suggest a child's food preferences are partially formed from the flavors they taste in breast milk. These varying flavors result from the foods in the mother's diet.
