Answer:
Cognitive process
Explanation:
The cognitive process is a process refers to several tasks the brains do consciously. They are the processing in charge of the processing of all the information we receive from the environment. We should be thankful for the cognition because it gives us the capacity to explore the information that we gather from the environment. A harmonious interaction between the cognitive process for fundamental so that we can analyze reality adequately and adapt it. It is a great thing due to cognitive process we can analyze and flexible to changes and demands of the situation.
Answer: random sampling
Explanation: Random sampling is a part of the sampling technique which each sample has an equal probability of being chosen. A situatuon whereby sample chosen randomly is supposed to be an unbiased representation of the total population. If at all, when sample does not represent the population, then the variation is called a sampling error.
Description: Random sampling is one of the easiest ways of collecting data from the total population. In random sampling, each member of the subset carries an equal opportunity of being part of the sampling process. For example, the total workforce in from is 500 and to conduct a survey, a sample group of 50 employees is selected to do the survey. In this scenario the population is the total number of employees in the firm and the sample group of 50 employees is the sample. Every member of the workforce has the same opportunity of being chosen because all the employees which were chosen to be part of the survey were selected randomly. But, when there is a possibility that the group or the sample does not represent the population as a whole, that means, any random variation is termed as a sampling error.
Another example of a simple random sample would be the names of 25 employees being chosen out of a group of company of 250 employees. In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.
Random sampling is usually used in science to conduct randomized control tests or for blinded experiments.
There are different kinds of investigations. The investigation that would it be best be use in observational data obtained outside of a laboratory rather than empirical data from controlled experiments is;
- an investigation to determine the structure of a protein.
<h3>How do one determine the structure of a protein?
</h3>
-
The common way used to study protein structures is the use of X-ray crystallography.
In this method, solid crystals of purified protein are put into an X-ray beam, and the pattern of deflected X rays is employed to know the positions of the atoms that is inside the protein crystal.
