The answer is; A

Since the earth was formed approximately 4.6 billion years ago, the heat that was generated during its formation has not been entirely lost. Some of the heat is still insulated inside the earth (below the crust) and is only lost very slowly over time. In addition, the earth hardly cools because the lost heat is replenished by the heat from radioactive elements that decay  in the earth’s core. Some of these radioactive elements are uranium.

<u>Answer:</u>

<em>Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk. </em>

<u>Explanation:</u>

<em>The leaves of touch me not plant stay upright due to turgor pressure. </em>It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.
