The correct answer is: b. it doesn’t often reflect reality.
While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
Answer:
1200ft
Explanation:
depth of water ranges from 0ft below the surface along major rivers and streams to a maximum estimated at more than 1200 ft below land surface on the southern slops oflarch mountain
Answer:

Answer:
B
Explanation:
The movement of plates (convergence, divergence etc) cause landforms such as mountains and volcanoes to form! It's really cool, isn't it!
Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.
