Answer:
b. Theories unify a broad range of observations and hypotheses.
Explanation:
In broad terms, theories are the set of principles that can or must be used to explain certain phenomena. It involves the involvement or inclusion of any set of principles to get to a conclusion.
Hypothesis, on the other hand, is just a term used for an assumption made. And this assumption may be made even before any observation has been done, a mere suggestion for how to proceed with things or an assumption about things.
Thus, scientific theories unify a broader range of observations that had been done, including any hypothesis. So, the <u>correct answer is option b</u>.
Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease
