Answer:

Option (2)

Explanation:

Index fossils are defined as those fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time. They had great significance in the field of paleontology. It helped in the construction of geological periods that are commonly used today. It basically helped in forming the geological time scale. The age of the rocks in which these fossils were embedded is easily determined by using radioactive dating techniques.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Hence, the correct answer is option (2).

When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated. what is this process cal
Shalnov [3]

When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated this process called as adaptive radiation.

<h3>What is Habitat?</h3>

The term "habitat" in ecology refers to the variety of resources, physical characteristics, and biotic elements that exist in a region and are necessary for a specific species to survive and reproduce. An animal's habitat can be thought of as the outward representation of its biological niche.

Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type." 

The physical elements could consist of things like soil, moisture, temperature range, and light intensity, for instance. The availability of food and the existence or absence of predators are examples of biotic variables. Every species has certain habitat needs; habitat generalist species can survive in a variety of environmental circumstances, whereas habitat specialist species need a specific habitat.

Why is scientific knowledge more reliable than other types of knowledge?
RUDIKE [14]

Answer:

D. Because science only uses facts that are proven 100% true through the use of  variables.

Explanation:

All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is  proven 100% true through the use of  variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.

Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of  variables.

Hope it helps!
