In western pennsylvania, and many other areas, deer are becoming a pest. true or false?

True.

Explanation:

In the United States, as of January this year, 24 states have reported cases of deer infected with chronic degenerative disease (CWD). Fatal and still little known, the disease destroys the nervous system, and is common in deer animals - and now scientists fear it could infect humans. For this reason, deer are being considered a possible pest in some states, including Pennsylvania.

The disease has earned the nickname "Zombie Deer Disease". This is because it leaves infected animals with skeletal appearance, causing weight loss, excessive salivation, and a glazed, expressionless look, similar to images of the undead. To date, no cases of the disease have been reported in humans, but studies have shown that primates, such as monkeys, can become infected by eating deer meat with CWD, or by contacting body fluids. These studies suggest that there may be a risk to humans as well.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
