Question

question 8 of 10
which environmental factor regulates whether genes that determine the sex
of a red - eared slider turtle are turned on or off?
a. nutrient availability
b. oxygen concentration
c. temperature during development
d. hours of daylight

Explanation:

Red - eared slider turtles have temperature - dependent sex determination. The temperature during their embryonic development determines whether the genes for male or female sex are expressed. For example, in some turtle species, higher temperatures during a critical period of development lead to the production of females, while lower temperatures lead to males. Nutrient availability, oxygen concentration, and hours of daylight do not play a role in regulating the sex - determining genes in this context.

Answer:

C. Temperature during development
