Ques: Q: We would genetically be all the same if genes did not have different what? Read this paragraph and choose the correct option from the provided answers: Chromosome, gene, locus and alleles are all related. What is the different between a gene and a locus? Between a gene and an allele? Chromosomes are composed of genes located at specific loci. And genes have different alleles. If genes did not have different alleles, we would genetically be all the same. What does that mean?. Choices: - atoms - antigens - bases - alleles A:
Ans: alleles

Ques: Q: Where does growth in length occur, above the root cap? Read this paragraph and choose the correct option from the provided answers: As shown in Figure below , the tip of a root is called the root cap . It consists of specialized cells that help regulate primary growth of the root at the tip. Above the root cap is primary meristem, where growth in length occurs. Choices: - primary tuber - vascular cambrium - apical meristem - primary meristem A:
Ans: primary meristem

Ques: Q: A catalyst decreases the amount of what resource that is required in order to begin a chemical reaction? Read this paragraph and choose the correct option from the provided answers: Catalysts are not reactants, but they help reactants come together so they can react. You can see one way this happens in the animation at the URL below. By helping reactants come together, a catalyst decreases the activation energy needed to start a chemical reaction. This speeds up the reaction. Choices: - positive energy - motion energy - kinetic energy - activation energy A:
Ans: activation energy

Ques: Q: What type of mass movement is a sudden movement of large blocks of rock and soil down a slope? Read this paragraph and choose the correct option from the provided answers: Two other types of mass movement are slump and creep. They usually aren't as destructive as landslides and mudslides. Slump is the sudden movement of large blocks of rock and soil down a slope. Creep is the very slow movement of rock and soil down a slope. It causes trees, fence posts, and other structures to tilt downhill. Choices: - deluge - resurgence - downturn - slump A:
Ans:
slump
