Q: Which kind of genetics approach involves mutating or deleting genes provides researchers with clues about gene function? Read this paragraph and choose the correct option from the provided answers: Watch this short video (http://openstaxcollege. org/l/transgenic) explaining how scientists create a transgenic animal. Although the classic methods of studying the function of genes began with a given phenotype and determined the genetic basis of that phenotype, modern techniques allow researchers to start at the DNA sequence level and ask: "What does this gene or DNA element do?" This technique, called reverse genetics, has resulted in reversing the classical genetic methodology. One example of this method is analogous to damaging a body part to determine its function. An insect that loses a wing cannot fly, which means that the wing's function is flight. The classic genetic method compares insects that cannot fly with insects that can fly, and observes that the non-flying insects have lost wings. Similarly in a reverse genetics approach, mutating or deleting genes provides researchers with clues about gene function. Alternately, reverse genetics can be used to cause a gene to overexpress itself to determine what phenotypic effects may occur. Choices: - possible genetics - impossible genetics - inverse genetics - reverse genetics A:
reverse genetics

Q: The zeros at the end of a number are known as what? Read this paragraph and choose the correct option from the provided answers: Trailing zeros, which are zeros at the end of a number, are significant only if the number has a decimal point. Thus, in 1,500, the two trailing zeros are not. Choices: - rest zeros - edge zeros - remaining zeros - trailing zeros A:
trailing zeros

Q: Q: Electrons flow through wires to create what? Read this paragraph and choose the correct option from the provided answers: 3. Electrical energy is the energy of moving electrons. Electrons flow through wires to create electric current. Choices: - electromagnetism - hydroelectric power - balanced reaction - electric current A:
A: electric current

Question: Q: Who is said to have dropped two objects of different masses from the tower of pisa? Read this paragraph and choose the correct option from the provided answers: Galileo's Experiment Galileo is said to have dropped two objects of different masses from the Tower of Pisa. He measured how long it took each to reach the ground. Since stopwatches weren't readily available, how do you think he measured their fall time? If the objects were the same size, but with different masses, what do you think he should have observed? Would this result be different if done on the Moon? PhET Explorations: Masses & Springs A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring. Choices: - darwin - copernicus - newton - galileo A:
Answer: galileo

Q: What nucleic acid stores the genetic information? Read this paragraph and choose the correct option from the provided answers: Nucleic acids are large polymers formed by linking nucleotides together and are found in every cell. Deoxyribonucleic acid (DNA) is the nucleic acid that stores genetic information. If all the DNA in a typical mammalian cell were stretched out end to end, it would extend more than 2 m. Ribonucleic acid (RNA) is the nucleic acid responsible for using the genetic information encoded in DNA to produce the thousands of proteins found in living organisms. Choices: - Nucleus - Ribosomes - molecule - dna A:
**Answer**
dna

Q: What part of the plant has a root end and a shoot end? Read this paragraph and choose the correct option from the provided answers: Choices: - radius - leaves - pistol - axis A:
axis
