Sewage Treatment Plants
Explanation:
Just did the test sorry its so late man.
Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
<h3>
Variation of ecological habitats within a species is characteristic of which type of diversity?</h3>
The variation of ecological habitats within a specie is character of the type of diversity is known as Ecosystem Diversity.
Ecosystem is defined as the different kinds of habitats, ecological processes and communities. A biological community is defined by the specie which occupy a specific area and the interactions between the species.
So we can conclude that: An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.

Answer: German scientist Alfred Wegener
Explanation: <em>In the early 1900s, the German scientist Alfred Wegener noticed that the coastlines of Africa and South America looked like they might fit together. He also discovered evidence that the same plant and animal fossils were found along the coasts of these continents, although they were now separated by vast oceans.</em>
