Answer the following question given this paragraph: Within a group, the ionization energy decreases as the size of the atom gets larger. On the graph, we see that the ionization energy increases as we go up the group to smaller atoms. In this situation, the first electron removed is farther from the nucleus as the atomic number (number of protons) increases. Being farther away from the positive attraction makes it easier for that electron to be pulled off. Q: Within a group, the ionization energy decreases as the size of the atom gets what? Choices: - brighter - smaller - lighter - larger A:
larger

Answer the following question given this paragraph: It can be really exciting to explore a big underground cave like the one in this picture. Do you know how caves form? Believe it or not, water is the answer. Water slowly dissolves rocks, especially certain types of rocks such as limestone. How does something as mild and harmless as water cause hard rocks to dissolve? In this chapter, you'll find out. Q: Caves form over time when what causes rocks like limestone to dissolve? Choices: - weather - acid - air - water A:
(Answer)
water
Ques: Answer the following question given this paragraph: The other idea is that evolution occurs by natural selection. Natural selection is the process in which living things with beneficial traits produce more offspring. As a result, their traits increase in the population over time. Q: Under which process do living things with beneficial traits produce more offspring? Choices: - migration - differentiation - evolution - natural selection A:
Ans: natural selection

Answer the following question given this paragraph: Green cyanobacteria on a lake make food by photosynthesis. Q: Green cyanobacteria on a lake produce food through what process? Choices: - spermatogenesis - glycolysis - reverse transferase - photosynthesis A:
(A).
photosynthesis
Ques:Answer the following question given this paragraph: Writing a formula for a ternary ionic compound also involves the same steps as for a binary ionic compound. Write the symbol and charge of the cation followed by the symbol and charge of the anion. Use the crisscross method to ensure that the final formula is neutral. Calcium nitrate is composed of a calcium cation and a nitrate anion. Q: What is composed of a calcium cation and a nitrate anion? Choices: - calcium carbonate - dynamite - nitrous oxide - calcium nitrate A:

Ans:calcium nitrate
Ques:Answer the following question given this paragraph: Ovulation, the release of an egg from the ovary, occurs at about the midpoint of the cycle. This would be around day 14 of a 28 day cycle. The egg is swept into the fallopian tube. If sperm is present, fertilization may occur. As sperm can only survive in the fallopian tube for up to a few days, fertilization can only occur within those few days post-ovulation. Q: Ovulation is the release of an egg from the what? Choices: - fallopian tubes - cervix - vagina - ovary A:

Ans:
ovary
