The value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is: D. amount of material that has not decayed.

<h3>What is a radioactive decay?</h3>

A radioactive decay can be defined as a radioactive process in which an unstable atomic nucleus undergoes a spontaneous transformation into one or more different atomic nuclei and simultaneously emits radiation, accompanied with a loss of energy.

<h3>The types of radioactive decay.</h3>

In Science, there are three main types of radioactive decay and these include the following:

Alpha decay
Beta decay
Gamma decay

Based on the information provided in the table (see attachment), we can reasonably infer and logically deduce that the value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is the amount of material that has not decayed.

An elephant has a long, powerful trunk. According to the ideas of Lamarck, how did the trait of long, powerful trunks develop in

Lubov Fominskaja [6]

Answer:

Gradually, as generations of elephants continued to selectively use and develop their trunks.

Explanation:

Jean-Baptiste Lamarck was famous French Naturalist. He was a soldier, a biologist and an academic. He gave an early theory of evolution known as the theory of Lamarckism.

It was Lamarck who first believed that elephants earlier had small trunks. But eventual when there was scarcity of food and water, the elephants stretched out its trunk to reached out for food such as trees and also water. And as a result their offspring inherited long and powerful trunk.

In his theory of Lamarckism, he believed that the species passes on its traits to the offspring which they acquired through their use in their lifetime. In this case, the elephants might have used their trunks in such a way that they became long and strong over time and they passed tis trait to their babies.
