Answer:

c.  Retrograde motion of the planets as they moved across the sky.

Explanation:

Ancient Greek philosophers were extremely intelligent people who propounded some ideas that have helped shape science to what it is today.

They had evidence for the spherical shape of the earth, the link between lunar phases and oceanic tides, and the existence of exoplanets, however, they did not have evidence for the retrograde motion of the planets as they moved across the sky because they believed that if the Earth moved around the Sun, then they would be able to see the stars from divergent points along Earth's orbit.

Why is it important that human chromosomes have many origins of replication
8_murik_8 [283]

Answer:

Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.

Explanation:

Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
