The answer would be : <span>It is a well supported explanation which cannot become a law.
A law and a theory are different you know. In fact, the law is universel. This applies for everything unlike a theory which explains in particular why something is happening.
Any doubts ?
Hope this helps !

Learning that occurs
when an organism makes a connection between two events is called "Associative
learning".<span>
The process involves associating various details or events to
learn a particular fact or information. For example one cannot imagine one eye
of his/her father, whenever he/she will imagine the whole face of their father
will make sense to mind and not single eye.</span>
 
        
             
        
        
        
Answer:
The correct answer is:
Includes at least two groups, one of which does not receive the experimental treatment. (B)
Explanation:
A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.
<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
 
        
             
        
        
        
Answer:
The universality of genetic code.
Explanation:
The DNA is a molecule made up from 4 different nucleotides (A, T, C or G). The sequence in which these nucleotides are ordered constitute a code that gives a cell instructions to produce a specific protein. This is called the genetic code. 
Every three nucleotides code for a specific amino acid. For example, ACG codes for Arginine, CUC codes for Proline, and so on.
The genetic code is universal. This means that in all living organisms, a particular sequence of three nucleotides will code for the same amino acid. This property guarantees that the human gene that codes for human insulin will also code for human insulin in bacteria.
