Which of the following correctly describes reproduction in turtles?
a. adults expend a lot of energy to care for offspring.
b. they lay their eggs in water to reduce water loss.
c. they mature rapidly to maximize reproduction opportunities.
d. offspring sex ratio may be determined by temperature.

The answer is D, but b could possibly be an answer too.

Explanation:

Turtle offspring sex ratio can be determined by the temperature. The temperature of the growing eggs is what decides the offspring's gender. This is called temperature-dependent sex determination, or TSD.

It could be B because some turtles do lay their eggs in underwater, but I don't think that they lay them underwater to reduce water loss.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
