In the Calvin cycle, which of the following best describes the sources of the elements that combine to make sugar?

A. The carbon and oxygen from carbon dioxide combines with the hydrogen and oxygen in water taken in during the Calvin cycle to make sugar.

B. The carbon, oxygen, and hydrogen from stored sugars are reprocessed during photosynthesis to make new sugar molecules.

C. The carbon and oxygen from carbon dioxide combine with the hydrogen taken from water during the light-dependent reactions to make sugars.

D. The carbon that is taken from carbon dioxide during the light-dependent reactions combines with the hydrogen and oxygen in water to make sugars.

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.

the answer is "a.) well–developed vascular system."

explanation:

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded

hope this any more questions i am here plz mark brainliest
