Answer:
1. Natural
2. Natural
3. Natural
4. Manipulative
5. Manipulative
6. Manipulative
7. Natural
Explanation:
In a natural experiment, the researcher can specify that any proposed health implications could be due to exposure to the toxic chemical, but proving its direct causation is difficult. Natural experiments are majorly fixed to promoting correlation, unlike the manipulative experiments which usually strongly reveals causation.
Manipulative experiments changes the amounts of a predictor factor and estimates how one or more variables acts to these changes. It is employed in a test cause-and-effect. It cannot be used for large experimental scales as they are for small spatial scales experiments.
Natural experiments makes use of an observational study on natural variation in the variable of interest. It is used for large spatial and temporal scales without the need for manipulations but cannot be used for the direction of cause-and-effect.
Yes because they are still the same species so they can reproduce
Acidic substance(s):
Vinegar contain acetic acid
Tomato Juice contain citric acid
Basic substance(s):
Baking Soda contains Sodium Carbonate
Neutral Substance(s):
In the process of producing sugar, the sugar cane juice is acidic but goes through a process where it's acidity is neutralized and as such the crystalline sugar ends up neutral
Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins.
