Answer:
There is no control group and variables were not addressed.
Explanation:
In the context, it is given that there is a dumping ground in a small town called Love Canal and harmful chemical waste of industries are dumped there. Lately, it is noticed that there were traces of the toxic substances on the walls of the schools and the hospitals. The hospitals also noticed that during the period of 1970 to 1980, there were increase in the number of the birth defects in the area. The people of the Love Canal has genetic abnormalities and the chemical waste is responsible for it.
Thus it can be concluded that there is a no such any control group in this case. The confounding variables like the comorbidities as well as the family history of the genetic defects were not addressed.
Answer:
Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution while Artificial selection is Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
The amount of ATP (Adenosine Triphosphate) produces is a characteristic that would best describe or distinguish glycolysis and the Krebs cycle from the electron transport chain.
Because of strong adhesion , a property of water which directly contributes to capillary action.
<h3>What is adhesion and what is capillary action?</h3>
- See in the plants there is always a need of cohesion and adhesion as we all know already which is the only way water can be up to the plants aerial parts.
- Though there are two more ways called transpiration pull and root pressure theory.
- Cohesion is the property of water which depicts its attraction properties.
- Adhesion is the property of the water which mean water molecules can stick to other particles or molecules.
- And is the same reason that is adhesion which gives a boost to capillary action.
