Answer the following question given this paragraph: A scientist is always trying to find the truth and discover new truths. How can you think like a scientist? Thinking like a scientist is based on asking and answering questions. Though you may not know it, you do this all day long. Scientists ask questions, and then make detailed observations to try to ask more specific questions and develop a hypothesis . They may design and perform an experiment to try to answer their question and test their hypothesis. From the results of their experiment, scientists draw conclusions . A conclusion describes what the evidence tells the scientist. Q: Scientists ask questions, and then make detailed observations to try to ask more specific questions, in order to develop what? Choices: - Tests - suggests - theories - hypothesis A:
hypothesis

Answer the following question given this paragraph: Cells in our bodies have an intricate mechanism for the manufacture of proteins. Humans have to use other techniques in order to synthesize the same proteins in a lab. The chemistry of peptide synthesis is complicated. Both active groups on an amino acid can react and the amino acid sequence must be a specific one in order for the protein to function. Robert Merrifield developed the first synthetic approach for making proteins in the lab, a manual approach which was lengthy and tedious (and, he won the Nobel Prize in Chemistry in 1984 for his work). Today however, automated systems can crank out a peptide in a very short period of time. Q: Robert merrifield developed the first synthetic approach for making what essential cell substances in the lab? Choices: - cells - acids - lipids - proteins A:
(Answer)
proteins
Ques: Answer the following question given this paragraph: Looking at the magnetism of the seafloor, scientists discovered something astonishing. Many times in Earth's history, the magnetic poles have switched positions. North becomes south, and south becomes north! When the north and south poles are aligned as they are now, geologists say it is normal polarity . When they are in the opposite position, they say that it is reversed polarity . Q: What is it called when poles are in opposite positions? Choices: - reversed bonding - polar effect - demagnetization - reversed polarity A:
Ans: reversed polarity

Answer the following question given this paragraph: If you've ever seen a kayak move down a fast-moving river, you know that remaining in the same place would be hard. The river current pulls the kayak along. Pushing the oars back against the water can move the kayak forward in the water, but that only accounts for part of the velocity. The kayak's motion is an example of classical addition of velocities. In classical physics, velocities add as vectors. The kayak's velocity is the vector sum of its velocity relative to the water and the water's velocity relative to the riverbank. Q: The kayak's motion in the water is an example of classical addition of what? Choices: - momentum - force - acceleration - velocities A:
(A).
velocities
Ques:Answer the following question given this paragraph: The deBroglie wave equations allows calculation of the wavelength of any moving object. Q: What type of equations allows calculation of the wavelength of any moving object? Choices: - fluctuations wave - disc wave - develpoment wave - debroglie wave A:

Ans:debroglie wave
