Answer 2

The most significant geological event of the Mesozoic era was the break up of a supercontinent. The correct option is D.

What was the geologic event of the Mesozoic era?

The most significant geologic event of the Mesozoic era was the breakup of the supercontinent Pangaea into smaller landmasses, which began in the Late Triassic period and continued throughout the Jurassic and Cretaceous periods.

This led to the formation of the modern-day continents and oceans, as well as significant changes in climate, sea levels, and biotic diversity. The breakup of Pangaea also resulted in the formation of numerous mountain ranges, including the Rockies, Andes, and Alps, as well as the opening of the Atlantic Ocean.

These geologic events had a profound impact on the evolution of life on Earth, including the diversification of dinosaurs and the rise of mammals.

Therefore, the correct option is D.

A plant limps when it's cells are ____
( turgid,flaccid,both)

Answers

Answer:

The correct answer is - flaccid.

Explanation:

A plant cell placed in a solution with lower water potential than the cell contents then water would leave the cell by the process of osmosis. Osmosis is the movement of a solvent through the semipermeable membrane due to concentration.

Due to plasmolysis, all the cytoplasm will be moved out of the cell that will cause the cell to become flaccid, and then the plant will limp or wilt. In turgidity, a plant cell appears swollen or distended from the turgor pressure.
