In scientific reasoning, a hypothesis is made before any applicable analysis has been done. A theory, on the opposite hand, is supported by evidence: it is a principle shaped as an effort to clarify things that have already been supported by knowledge<span>.
</span>For example: “It's bright outside.”
Hypothesis: A projected clarification for a development created as a place to begin for additional investigation.
Theory: A well-substantiated rationalization nonheritable through the methodology and repeatedly tested and confirmed through observation and experimentation
Gymnosperms:- non-flowering,exposed seeds,pine or fir fruit.
angiosperms:- flowering,seeds enclosed in fruit,garden flowers and tomatoes
Answer: C. The environment changed suddenly from a shallow ocean setting to a river system.
Explanation:
The presence of the fossils of shallow oceanic creatures like corals points to the fact that the environment was a shallow ocean at some point. There is also a presence of a layer on top of that which points to a river system.
The fact that the oceanic fossils are beneath the river system layer means that the ocean came first and the river system layer came second. The environment must therefore have been a shallow ocean setting that changed into a river system.
<h3>Correct answer choice is:</h3><h2>B. Populations increase and decrease in a regular predictable pattern.</h2><h3>Explanation:</h3>
A population cycle in biology is a process where populations increase and decrease over an anticipated duration of time. There are many classes where population figures have logically anticipated models of reform although the full incentives for population cycles are one of the significant unsolved environmental difficulties.
