Ques: Answer the following question given this paragraph: Figure 11.35 (a) Capillary action depends on the radius of a tube. The smaller the tube, the greater the height reached. The height is negligible for large-radius tubes. (b) A denser fluid in the same tube rises to a smaller height, all other factors being the same. Q: What domain-level category of cells can contain more than 1000 times the dna found in a typical bacterial cell? Choices: - chromosomes - mutations - genetic - eukaryotic A:
Ans: eukaryotic

Ques: Answer the following question given this paragraph: Group 15 of the periodic table is also called the nitrogen group. The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) ( Figure below ) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity. Nitrogen, for example, is not very reactive at all, whereas phosphorus is very reactive and found naturally only in combination with other substances. All group 15 elements are solids, except for nitrogen, which is a gas. Q: Group 15 of the periodic table is also called which group? Choices: - oxygen - potassium - hydrogen - nitrogen A:
Ans: nitrogen

Ques: Answer the following question given this paragraph: Lakes, ponds, streams, springs, and wetlands are fresh water bodies. The organisms that live in them are part of freshwater ecosystems. These ecosystems vary by temperature, pressure (in lakes), and the amount of light that penetrates. The type of plants that grow in these ecosystems varies. Q: Lakes, ponds, streams, springs, and wetlands are? Choices: - salt water bodies - man-made structures - land formations - fresh water bodies A:
Ans: fresh water bodies

Choices: - methane - hydrogen and helium - water and carbon dioxide - water and oxygen A:
