Answer:
All pieces of land on Earth were once joined together.
Earth's surface is covered with continental plates.
All the continents are moving at a slow pace.
Explanation:
According to the Wegener, at first all continents are fuse together make a supercontinent which later broke apart into seven large masses of land. All the continents are moving away from each other at very slow rate. The surface of earth is covered with continental plates that is responsible for the breaking and movement of continents from each other.
Answer:
Mitosis produces two daughter cells and meiosis produces four daughter cells
Explanation:
In mitosis, you start off with one parent cell, and it duplicates itself, so as you could see, you would have the original cell as well as the duplicated version, which is a total of 2. In meiosis, there are two main phases, Meiosis I and Meiosis II. The first phase produces two cells and the second phase takes those two cells to form four daughter cells / gametes
Every species plays its part in an ecosystem, creating a perfect balance. Introducing a species or exterminating one could throw off that balance, causing devastating results. For example, an eagle, a snake, a rat, and a grasshopper. The leaves are eaten by grasshoppers. The grasshoppers are eaten by rats. The rats are eaten by snakes. The snakes are eaten by eagles. Let's say that you decide to kill off the grasshoppers. The balance would be thrown off. Because there's no animal or insect to eat the grass, the grass will grow and grow and grow. Since the grasshopper was also a food source for the rats, the the rats will most likely start to die out because they have no grasshoppers to eat. Same goes with the snakes, since the rats die off, the snakes die too cause they have no rats to eat. Same with the eagle. Introducing a species will, in a way do the same thing as well. Introducing a species will cause a new demand for food and space, effecting an ecosystem. For example, there's a forest. The forest is a home to many animals, especially the birds that live in the trees. Let's say you decide to place wood eating bugs in that forest. Their food source would be the trees, the very home of those birds. If they start eating all the trees, then the birds would have to home to go to, the habitat of other animals may also be destroyed, all because the balance of an ecosystem was thrown off. I hope this helps!
<u>Answer</u>: Aerial roots allow the orchid to attach itself to trees.
<u>Explanation</u>:
- The roots of the plant that grow above the ground are known as aerial roots.
- These aerial roots are found in orchids to attach to the tree.
- The plant may or may not retain its terrestrial root.
- Examples of the orchids with aerial roots are climbing orchids and epiphytic orchids.
- These roots help the plant to firmly stay on the branches of the trees and compete with others for sunlight .
I would likely go with A) Country B will have a high level of poverty because the richness and even distribution of Country A's resources reduce the probability of poverty. The citizens have greater access to resources that will sustain them. In Country B, however, the low distribution of the resources means citizens in areas where they are not as concentrated will suffer and likely have a high level of poverty.
