Answer:

C. Water molecules flow in both directions at the same rate.

Explanation:

The relative concentration of solutions indicates the direction of movement of water across the semi-permeable membrane. An isotonic solution is that which has the same osmolarity of a cell. As a result, there is no concentration gradient for water across the cell membrane. In this case, water molecules will move through the plasma membrane in both directions with the same rate. Thus, there will be no net movement of water into or out of the cell.

705 over 224 divide by 224 over 224

dybincka [34]

(705/224) / (224/224)
224/224 = 1.
So (705/224) / (224/224) = (705/224) / (1/1).
Dividing 2 fractions is equal to multiplying the first fraction by the inverse of the second:
(705/224) / (1/1) = (705/224) * (1/1) = 705/224.

Hope this Helps! :)

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

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
