The correct answer to this open question is the following.
The process of learning involves perception, the way we perceive things from the environment or in school. Then it comes to process the information, which means the wat we think about what we are observing. We reflect on it and conceptualize to better understand. Then, we have to put into action what we learn in order to totally understand it. To master what we learn, we have to practice it once or twice until we get it.
Answer:
B. A precipitin test is the correct answer
Explanation:
To determine whether a bloodstain is of human or animal origin, the serologist will perform: A precipitin test.
The precipitin test is based on the interaction between antigen and antibody which results in the formation of antigen-antibody complexes and this visible precipitate antigen-antibody complexes is called precipitin.
Precipitin test is a serological test where antibody reacts with soluble antigen to produce a precipitate.
The precipitin test is used to distinguished whether the blood sample is from human or different sources.
The choices are:
A. ) standardization.
B) predictive validity.
C) reliability.
<span>D) content validity.
The answer is A. standardization. He was comparing his score to other average test-takers. From there he could reflect if the test is a standard exam for Math. He most probably would see average test takers get approximately at least his score. </span>
