Ques: Q: Attraction of a material by a magnet is an example of what type of property? Read this paragraph and choose the correct option from the provided answers: Iron filings are attracted by a magnet. This is a physical property of iron but not of most other materials, including sand. How could you use this difference in physical properties to separate a mixture of iron filings and sand?. Choices: - thermal - chemical - transitive - physical A:
Ans: physical

Ques: Q: What are female gonads normally called? Read this paragraph and choose the correct option from the provided answers: Animals often have gonads , organs that produce eggs or sperm. The male gonads are the testes , and the female gonads are the ovaries . Testes produce sperm; ovaries produce eggs. Sperm and egg, the two sex cells, are known as gametes , and can combine two different ways, both of which combine the genetic material from the two parents. Gametes have half the amount of the genetic material of a regular body cell; they are haploid cells. In humans, gametes have one set of 23 chromosomes. Gametes are produced through a special type of cell division known as meiosis . Normal human cells have 46 chromosomes. They are diploid cells, with two sets of 23 chromosomes (23 pairs). Choices: - testes - tubules - glands - ovaries A:
Ans: ovaries

Ques: Q: Arachidic, stearic, and palmitic fatty acids are examples of what type of fatty acid? Read this paragraph and choose the correct option from the provided answers: Saturated and Unsaturated Fatty Acids. Saturated fatty acids include arachidic, stearic, and palmitic fatty acids. Unsaturated fatty acids include all the other fatty acids in the figure. Notice how all the unsaturated fatty acids have bent chains, whereas the saturated fatty acids have straight chains. Choices: - neutral - integral - compacted - saturated A:
Ans: saturated

Ques: Q: What is the term for crops that are genetically modified with new genes that code for traits useful to humans? Read this paragraph and choose the correct option from the provided answers: Biotechnology has been used to create transgenic crops. Transgenic crops are genetically modified with new genes that code for traits useful to humans. The diagram in Figure below shows how a transgenic crop is created. You can learn more about how scientists create transgenic crops with the interactive animation "Engineer a Crop: Transgenic Manipulation" at this link: http://www. pbs. org/wgbh/harvest/engineer/transgen. html . Choices: - mutant - embryonic - carcinogenic - transgenic A:
Ans:
transgenic
