Answer:

The correct answer is crossing over.

Explanation:

Crossing over maintains genetic diversity within a population of an organism, allows the various genetic combination to be transferred from parents to their offspring.  

Crossing over of chromatids pair occurs during prophase-I, it is the very first phase of meiosis-1. In this phase, the 3rd stage is pachytene in which genetic recombination occurs because of the formation of recombinant nodules.

The first phase of meiosis II is prophase II in which the nuclear envelope breaks and the formation of the spindle apparatus occurs.

Thus, the correct answer is crossing over.

The Eocene period exists in Earth’s history around 34 MYA. What could a scientist do to determine what era the Eocene period bel
Sloan [31]

Answer:

To understand what era the Eocene period belongs to on the geologic time scale, the scientist would have to examine the Cenozoic era to understand all information related to it.

Explanation:

First, let's start with an explanation of terms.

  • MYA simply means Millions of Years Ago
  • Time Scale is a sequence or organisation of events which is used as a yardstick to measure the duration of history or how long the earth has existed.
  • Eocene Period refers to the geological epoch that lasted from about fifty-six to approximately forty MYA. It is also defined as the second epoch of the Paleogene Period within the modern Cenozoic Era.  

Given the definition of the Eocene Period, to understand what era an Eocene period belongs to, the person must carefully study the Cenozoic era.

Cheers!
