In an alternate version of the universe, the earth rotates around its axis at the same speed with which it revolves around the sun (ie. 365 of our days for one rotation/r). Think about what this means for the time period of day and night in "alter-Earth". What would be the approximate value of the period of the rhythm that would evolve in most species in this world?

a. 365 days
b. 182.5 days
c. 730 days
d. There will be no rhythms based on the light cycle

The Correct option is A "365 days"

Explanation:

Earth pivots on its hub once every 24 hrs and species have developed to organize their exercises dependent on these day-night cycles showing endogenously rehashing circadian rhythms.  

Then again, in an adjust earth, every revolution on its hub takes 365 days. This time-span is same as the time it takes to rotate around the sun (365 days).

The time-frame of every day and night in this adjust earth will be 182.5 days. The estimated estimation of the time of the beat that would develop in many species in this modify earth will be 365 days.
