Answer the following question given this paragraph: Many of the fibers that compose the materials for our clothes are naturally occurring. Silk and cotton are examples of natural fibers. Silk is produced by the silkworm, and cotton is grown as a plant. However, several chemical processes are used to treat silk thread so that it is shrink-resistant and will repel water. Chemical dyes are frequently used to color various fabrics. Cleaning requires special soaps or chemicals used to dry-clean materials. Cotton will grow better if the boll weevil (an insect that kills the plant) is eliminated with the use of specific insecticides. Ironing of cotton is made easier by the use of chemicals that produce a permanent press in the material. Q: Silk and cotton are examples of what type of fibers? Choices: - mechanical - artificial - coral - natural A:
natural

Answer the following question given this paragraph: How about both? That would suggest that fungi can produce both diploid and haploid cells, which they can. Shown above are fungi mycelia and haploid spores. Spores allow fungi to reproduce through unfavorable conditions. Q: What particles allow fungi to reproduce through unfavorable conditions? Choices: - bosons - atoms - quarks - spores A:
(Answer)
spores

Answer the following question given this paragraph: Cellulose is a compound found in plants. The chief component of cellulose is carbon. Cellulose is one of many carbon-based compounds that make up living things. In fact, carbon-based compounds are the most common type of compound on Earth. More than 90 percent of all known compounds contain carbon. Do you know why carbon is found in so many compounds? Read on to find out. Q: What are the most common types of compounds found on earth? Choices: - sodium - based compounds - ionic compounds - hydrogen-based compounds - carbon-based compounds A:
(A).
carbon-based compounds
Ques:Answer the following question given this paragraph: In biomes with cold climates, plants may adapt by becoming dormant during the coldest part of the year. Dormancy is a state in which a plant slows down cellular activities and may shed its leaves. Animals also adapt to cold temperatures. One way is with insulation in the form of fur and fat. This is how the polar bears in Figure below stay warm. Q: What do you call the state in which a plant slows down cellular activities and may shed its leaves? Choices: - recession - hibernation - germination - dormancy A:

Ans:dormancy
Answer the following question given this paragraph: Primary pollutants enter the air directly. Some are released by natural processes, like ash from volcanoes. Most are released by human activities. Carbon oxides are released when fossil fuels burn. Q: What type of pollutants enter the air directly? Choices: - secondary - liquid - carbon - primary A:
primary
