Answer the following question given this paragraph: The two photos in Figure above represent two different biomes. A biome is a group of similar ecosystems with the same general abiotic factors and primary producers. Producers are organisms that produce food for themselves and other organisms. Biomes may be terrestrial or aquatic. Q: What is a group of similar ecosystems with the same general abiotic factors and primary producers? A:

OPTIONS:
- ecoregion
- family
- taxon
- biome

Answer: biome

Problem: OPTIONS:
- enzymes
- collagen
- essential amino acids
- antibodies
Q: Answer the following question given this paragraph: Antibodies These proteins recognize and combine with harmful materials, including both toxic chemicals and invasive microorganisms (such as bacteria and viruses). When an antibody binds to its target, it is tagged for destruction. This tag is recognized by white blood cells, which complete the process. Some antibodies also partially or completely deactivate their targets while waiting for further help from white blood cells. Q: Which proteins recognize and combine with harmful materials, including both toxic chemicals and invasive microorganisms? A:
Answer: antibodies

Problem:OPTIONS:
- metabolism
- erosion
- destruction
- corrosion

Answer the following question given this paragraph: The driving force to combine with nonmetals to create ionic compounds varies quite a bit between different metals. Some pure metals, like cesium and potassium, are so eager to react that they must be stored under oil to avoid an immediate reaction with the oxygen present in air. Others, like platinum and gold, are stable enough that they can be found in nature as pure metals rather than as the cationic portion of an ionic compound. Gradual degradation of a material due to its exposure to the environment is known as corrosion . Metals like gold and platinum are unusually resistant to corrosion, which makes them especially valuable for both structural and decorative purposes. Q: Gradual degradation of a material due to its exposure to the environment is known as what? A:
****
A: corrosion

Answer the following question given this paragraph: All eukaryotic cells have a nucleus and other organelles. Each organelle has a special job to do. Q: Along with other organelles, all eukaryotic cells possess what structure? A:
OPTIONS:
- chromosomes
- cell walls
- flagella
- nucleus
nucleus

Answer the following question given this paragraph: Other applications of carbonates include glass makingwhere carbonate ions serve as a source of oxide ionsand synthesis of oxides. Hydrogen carbonates are amphoteric because they act as both weak acids and weak bases. Hydrogen carbonate ions act as acids and react with solutions of soluble hydroxides to form a carbonate and water: KHCO 3(aq) + KOH(aq) K 2 CO 3(aq) + H 2 O(l) With acids, hydrogen carbonates form a salt, carbon dioxide, and water. Baking soda (bicarbonate of soda or sodium bicarbonate) is sodium hydrogen carbonate. Baking powder contains baking soda and a solid acid such as potassium hydrogen tartrate (cream of tartar), KHC4H4O6. As long as the powder is dry, no reaction occurs; immediately after the addition of water, the acid reacts with the hydrogen carbonate ions to form carbon dioxide: HC 4 H 4 O 6 (aq) + HCO 3 (aq) C 4 H 4 O 6 2(aq) + CO 2(g) + H 2 O(l) Dough will trap the carbon dioxide, causing it to expand during baking, producing the characteristic texture of baked goods. Q: Substances that act as both weak acids and bases are said to be what? A:
OPTIONS:
- amphiphilic
- hygroscopic
- atmospheric
- amphoteric

Answer: amphoteric
