At the beginning of the cenozoic, the distribution of continents changed from that seen throughout most of the mesozoic. which of these best describes the new distribution of continents?
a. a single land mass that allowed for easy moevement of animals between continents
b. individual land masses that are moving towards the poles
c. most of the land masses are located near the equator
d. the continents were already in the positions that we have in the current time.

b. individual land masses that are moving towards the poles

Explanation:

The Mesozoic started with the Triassic period, 251.9 million years ago, after a mass extinction that wiped out most of life on Earth. At this moment, all the continents were part of a continuous landmass called Pangaea. By the Late Jurassic, the continents started to drift towards the poles. Africa and South America stay move from the southern hemisfere towards the Equator, Antartica and Australia move towards the south pole. It is during this time that we have two continents: Laurasia in the north, comprised of Europe, North America, Russia, China, and parts of Central Asia; and Gondwana, comprised of South America, Africa, Australia, India and Antarctica.

Towards the end of the Mesozoic, Laurasia and Gondwana also start to split. Laurasia breaks up and still occupies the Northern hemisphere, but pieces of broken Gondwana drifted north, such as South America, Africa and India. Of these, Africa collided with Europe and originated the Italian peninsula, the Iberian peninsula, and the Balkan region. The collision of India with China, Tibet and Russia prompted the beginning of the formation of the Himalaya.

By the beginning of the Cenozoic, Laurasia and Gondwana had split into several individual landmasses, most of them in the Northern Hemisphere.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
