Answer:

A. global temperatures drop several degrees after several massive volcanic eruptions

Explanation:

  • If any event causes widespread destruction of life on earth that would rapidly decrease the biodiversity, then such an event is called a mass extinction.
  • All the organisms living on the planet require an optimum temperature for their survival, besides the temperature also influences the geological activities such as the weather, rainfall patterns, survival of plants and hence the amount of oxygen and control of pollution.
  • Due to the importance of temperature, the drop in it globally would have a major impact on the living beigns.
  • Since a drop in global temperatures would affect the organisms all over the planet this will lead to mass extinction.

Plant cells, unlike animal cells, are characterized by the presence of a ________.
expeople1 [14]

B. Cell wall and a central vacuole

The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright.  Animal cells are more fluid.

The central vacuole is a large region in the cell that stores nutrients and fluids.  Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.

Hope this helps!!
