These air masses move around the America they can begin to acquire additional attributes.In winter an arctic air mass(cold and dry) can move over the ocean, picking up some warmth and moisture from the warmer ocean and becoming a maritime polar air mass.<span> If that same polar air mass moves south from Canada into the southern U.S. it will pick up some of the warmth of the ground, but due to lack of moisture it remains very dry. This is called a continental polar air mass.</span>
Question is which is NOT a good technique.
Answer is "B" and here's why:
A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.
B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
Answer & Explanation
The use of extra anabolic steroids has been termed ''unethical''. Therefore, the research would be unethical to subject participants to extra doses of different steroids.
In sports, the use of anabolic steroids in order to boost personal performance is regarded as doping and anabolic steroids are listed as banned substances.
Answer is it will be unethical to expose participants to high doses of multiple steroids
