The answer is B
Explanation. The density explains the amount of mass for how small or large an object is. Best way to test density is with water. If it is MORE DENSE (heavier in small area) it will sink.
Plasticity is to be molded. You can mold plastic is is bendable and heats up easily to give the advantage of being reshaped
The answer is <span>A. Decrease in genetic variation
</span><span>
A founder effect is a result of a geographical separation of a few individuals from the original population. Those few founding individuals will form a new population so they are founders. In this new population, there will be present alleles of the few founding individuals. However, those few founding individuals do not represent a whole genetic variation of the old population, but only some part of it.
Imagine a population of fish in which there are yellow, green, blue, and red colored fish. In the population, there is a genetic variation. But, if a few green-colored and red-colored fish geographically separate from the population and form a new population, in the new population there will be decreased genetic variation (because there are only green and red fish compared to the old population where are fish in 4 different colors).</span>
B. An oak tree grows from the seed material in an acorn
Answer:
The answer is C - Theories are supported with evidence and do explain what we see in the world (Ex: The cell theory) The evidence can change or be added on to when new evidence is found.
Explanation:
A - Theories are not hypotheses but theories start out as hypotheses. When the hypotheses gain enough evidence, they can start to become a theory, and this is after many experimentations and testings and trials and research.
B - Everyone can have theories, not just scientists. Many theories have been made on social media platforms such as r e d d i t or y o u t u b e. Some of these theories are conspiracy theories that people make based on some evidence they gather about a topic and sometimes believe is true even though it may not be true.
D - Theories are not opinions but are backed up with evidence and may have went through many trials and errors to become where it is.
E - Theories are testable ideas and scientists are always trying to make theories to be the best of what it can be. Theories have to be tested over and over again to make sure that whatever the theory is about is still valid and works.
