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.
The answer is: <span>D. The population of bluebirds will decrease, leading to an eventual decrease in the number of predators.
The unwanted </span><span>dumping of chemicals causes a decrease in the number of insects. The insects are eaten by bluebirds, but if there is not enough food for the bluebirds, they will die- decrease of birds. If there are less bluebirds, their predators will have less food, so many of them will also die.</span>
I think its c because both groups receive the same amount of of sunlight
Answer:
sorry wish I could help I just don't understand it ??
Answer:
The Inter-Tropical Convergence Zone (ITCZ)region gets the most direct sunlight at any given period in time. This in turn causes air to be unstable with a drop in pressure and rise of air which cools and condenses into clouds to form precipitation causing the wet season in the tropics.
In this region, the sun is directly or almost overhead as seen during summer periods in the tropics.
Only in areas of the North and South of the ITCZ known as doldrums which at times are parallel to the ITCZ do we have high pressure that aren't conducive to precipitation causing dry season in the tropics.
In the ITCZ zone, we also have the tropical rain forests along the equator with huge amount of all round rain for the year.
Along the equator, on either side of the rain forests we have the dry and wet forests with the savannah to the North of this region and the southern hemisphere to the south of these forests since these forests are seen mostly in the ITCZ than the savannahs.
Rain shadows and ocean cueeebts may at times cause some savannahs to be along the equator and some rain forests -wet and dry forests- to be positioned further form the equator.
