Q: Name the term used to described prokaryotes that require oxygen. Read this paragraph and choose the correct option from the provided answers: Prokaryotes that need oxygen are described as aerobic. They use oxygen for cellular respiration. Examples include the prokaryotes that live on your skin. Choices: - anaerobic - hydrophylic - mouth breathers - aerobic A:
aerobic

Q: What involves the reaction of a hydrocarbon with oxygen gas to produce water and carbon dioxide? Read this paragraph and choose the correct option from the provided answers: Combustion reactions involve the reaction of a hydrocarbon with oxygen gas to produce water and carbon dioxide. Choices: - hydrogen reactions - chemical reactions - material reactions - combustion reactions A:
combustion reactions

Q: Q: Human actions such as plowing, logging, construction and other actions contribute to what kind of erosion? Read this paragraph and choose the correct option from the provided answers: Many human actions make it easier for wind and water to carry away soil. They include plowing, logging, construction, and even some types of recreation. Choices: - weathering - flooding - wind erosion - soil erosion A:
A: soil erosion

Question: Q: What forms when a glacier scrapes a large hole in the ground? Read this paragraph and choose the correct option from the provided answers: The depression that allows water to collect to form a lake may come about in a variety of ways. The Great Lakes, for example, are glacial lakes. A glacial lake forms when a glacier scrapes a large hole in the ground. When the glacier melts, the water fills the hole and forms a lake. A kettle lake forms in the sediment left by a glacier when a block of ice melts. Kettle lakes are found where continental glaciers once covered the land ( Figure ' below ). Over time lakes get water from rain, streams, and groundwater coming to the surface. Choices: - crater lake - underground cavern - glacial hill - glacial lake A:
Answer: glacial lake

Q: What causes rivers to always flow downhill? Read this paragraph and choose the correct option from the provided answers: Currents are like rivers flowing through the ocean. Rivers always flow downhill because of gravity. What do you think causes ocean currents to flow?. Choices: - slope - pressure - diffusion - gravity A:
**Answer**
gravity

Q: What replicates in the s phase of interphase, resulting in chromosomes composed of two linked sister chromatids? Read this paragraph and choose the correct option from the provided answers: DNA replicates in the S phase of interphase. After replication, the chromosomes are composed of two linked sister chromatids. When fully compact, the pairs of identically packed chromosomes are bound to each other by cohesin proteins. The connection between the sister chromatids is closest in a region called the centromere. The conjoined sister chromatids, with a diameter of about 1 m, are visible under a light microscope. The centromeric region is highly condensed and thus will appear as a constricted area. Choices: - protein - hormones - RNA - dna A:
dna
