I believe that is false. The canopy can block 95% of the light. I might be wrong about which kind of forest though.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
Answer:
The pitch is the independent variable.
The dogs are the dependent variable.
Explanation:
An independent variable is something that you can control such as how high or low the pitch is. The dependent variable is the variable that is dependent on the independent variable. The dependent variable is the one that shows the results.
