Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct

Explain the systems and structures and how they are used by the plant to maintain homeostasis.

bazaltina [42]

Answer:

The given image shows - the Stomata that helps in maintaining homeostasis in the plants.

Explanation:

Stomata are the small structure resemble as tiny or pinholes that found on the underside of the leaves and play many roles in the plant. Stomata help in the gas exchange and also helps in transpiration. It allows oxygen a gas and water in vapor form from the leaves to the outer environment and let carbon dioxide inside the cell.

This system also helps in transpiration by closing and opening stomata with the help of their guard cell by becoming turgid and flaccid by osmotic pressure.
