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:
yes,because rabbit is one of the food sources of fox .If rabbit population decrease, fox population will also decease due to lack of food.

Some reflexes are theorized to exist because they have the survival
value. Sigmund Freud First to theorize that we pass through different stages, behaviour
is governed by the reflexes that we are born with, start to develop schemata,
but need to develop permanence.
If light strikes one receptor, the net effect is to excite the nearest bipolar cell and inhibit other bipolar cells to the side because of the contributions from horizontal cells.
<u>Explanation:</u>
On striking the receptor with light, the nearest bipolar cells respond to the light at the most inside the circumference. The bipolar cells which are outside the circumference responds least to the phenomena. Overall, the net effect thereby when seen, is to excite the nearest bipolar cells.
By the excitement of nearest bipolar cells, other farther cells are inhibited as a result as the horizontal cells are also excited and they contribute to inhibit the bipolar cells which are not near to the receptor cells in the eyes.
The option that is true of genes found on chromosomes is that D. they determine the inherited traits of an organism.
Genes are inherited - so those are the things that we get from our parents and other ancestors. It is easy to determine which of these genes a child is going to inherit - the doctors just need to take a look at the chromosomes, because genes are located there.
