Answer:
his independent variable (brain concussion) appears to have construct validity
Explanation:
Construct validity refers to how well a certain test actually able to measures what it claims or measuring. (being done after ensuring that all the data is relevant and the method that used for measurement is unbiased)
Researchers will conducted test for construct validity in order to find out how much the result of the test will deviate from real life application.
The single-stranded genomic DNA, the SDS, and the cellular waste are precipitated in a high-salt environment that is created by the potassium ion from the potassium acetate.
After centrifugation, the supernatant will still contain your plasmid DNA. Plant DNA has frequently been extracted using the potassium acetate method.
It has been suggested in situations when several markers need to be evaluated on the same samples since it generates enough DNA to test a high number of markers. Typically, laboratory procedures call for the use of potassium acetate.
In molecular biology applications, potassium acetate precipitates sodium dodecyl sulfate (SDS) and SDS-bound proteins to enable their removal from DNA. It may also be employed as a salt for the ethanol precipitation of DNA.

Hello!
Early Aryans were nomadic, they used to travel from place to place in order to find food. During meals they ate fruits, vegetables, fish and meat from their herds; this means that "herder" is a correct option, but once they settled in Nortwestern India, they learnt to farm the soil, so I would say that another correct option is the fourth one, "farmer"; they became farmers when they finally settled in India. Also, they were warlike people, they used to pass on war stories from one generation to another and also played fighting games, so the fifth one, "warrior", is the last correct option.
I hope this may help you
