Hurryyy ! what observation did this geocentric model of the solar system to explain a. orbit speed b. the phases of venus c. retrograde motion d. the rising of the sun

The answer is retrograde motion. That course honestly kills me

The correct answer is option C, The retrograde motion

Explanation:

In a geocentric model, a retrograde motion is represented by –  

a)A planet is  shown moving on a small circular path  

b)Also the same planet is shown to move on a larger circular path around planet earth as earth is considered to be the center of the geocentric model of solar system

In this figure, both the conditions of retrograde motion are full filled and thus option C is the correct answer.  

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
