Answer:
Low validity and low reliability.
Explanation:
Structured interview may be defined as a type of interview in which the interviewer has already decided the question. The questions are asked in the same series during the interview.
Diagnostician A has classified the individual as “odd” cluster. The Diagnostician B classifies an individual's personality as“dramatic” cluster. The structured interview has low reliability. The structured interview has low validity also as compared with other type of interview.
The minimum pH is 4 whereas the maximum pH is 14. The optimum pH of enzyme Y is about 9.
The minimum pH is 4 whereas the maximum pH is 14. Within this range, Enzyme Y will work.
As shown in the graph, as the pH increases so does the rate of Enzyme action. The optimum pH of enzyme Y is about 9. The rate of enzyme action increase till a pH of 9, then it begins to decrease.

Answer: Light can influence gene expression at caterpillar stage which can further influence butterfly wing development. This hypothesis was proved by Thomas Hunt Morgan in 1917 a biologist who conducted studies on butterflies from two different species : <u>Vanessa</u> <u>urtica </u> and <u>Vanessa</u> <u>io </u> caterpillars under red, green, or blue light whereas other caterpillars were kept in the dark. He found that there were differences in color and size of wings of butterflies exposed to different light conditions. Exposure to red light resulted in bright colored wings while exposure to green light resulted in dusky wings. Blue light and dark light resulted in paler colored wings. Also, V. urtica caterpillars reared under blue light and V.io butterflies reared in dark wings developed were larger in size.
Therefore light which is an external environmental factor can influence gene expression which can further influence phenotype of the organism.
Hence in the given situation butterfly would show differences in their wing color if in the caterpillar stage they were grown in dark or bright white light.
Answer:
I would rather be a multicellular organism.
Explanation:
I say so because if I were to be a single cell organism, how would my life be? Would I still be able to think and move as I do as a multicellular organism? The answer would be no, I wouldnt. Single celled organisms like bacteria have a nucleus, unlike multicellular organisms. I would like to stay the way I am. (Just my opinion)
