Answer the following question given this paragraph: Look at the Figure below of water (H 2 O) and hydrogen peroxide (H 2 O 2 ), and read about these two compounds. Both compounds consist of hydrogen and oxygen, but they have different ratios of the two elements. As a result, water and hydrogen peroxide are different compounds with different properties. If you've ever used hydrogen peroxide to disinfect a cut, then you know that it is very different from water!. Q: What elements do water and hydrogen peroxide consist of? Choices: - carbon and oxygen - calcium and oxygen - hydrogen and helium - hydrogen and oxygen A:
hydrogen and oxygen
Answer the following question given this paragraph: Nutrients the body needs in relatively small amounts are called micronutrients . They include vitamins and minerals. Vitamins are organic compounds that are needed by the body to function properly. Several vitamins are described in Table below . Vitamins play many roles in good health, ranging from maintaining good vision to helping blood clot. Vitamin B12 is produced by bacteria in the large intestine. Vitamin D is synthesized by the skin when it is exposed to UV light. Most other vitamins must be obtained from foods like those listed in Table below . Q: What is the term for nutrients the body needs in relatively small amounts, including vitamins and minerals? Choices: - minor nutrients - insignificant nutrients - trace nutrients - micronutrients A:
micronutrients
Q: Answer the following question given this paragraph: A cell that does not have a rigid cell wall (such as a red blood cell), will swell and lyse (burst) when placed in a hypotonic solution. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis. Animal cells tend to do best in an isotonic environment, plant cells tend to do best in a hypotonic environment. This is demonstrated in Figure below . Q: The plasma membrane pulls away from the cell wall as it shrivels. what is this process called? Choices: - sporozoans - fluctuations - osmosis - plasmolysis A:
A: plasmolysis
Question: Answer the following question given this paragraph: Traits are controlled by genes on chromosomes. A gene may have different versions called alleles. Q: A gene may have different versions called what? Choices: - genomes - peptides - locus - alleles A:
Answer: alleles
*Question*
Answer the following question given this paragraph: The cells you have learned about so far are much smaller than the period at the end of this sentence, so they are normally measured on a very small scale. The smallest prokaryotic cell currently known has a diameter of only 400 nm. Eukaryotic cells normally range between 1 100m in diameter. The mouse cells in Figure above are about 10 m in diameter. One exception, however, is eggs . Eggs contain the largest known single cell, and the ostrich egg is the largest of them all. The ostrich egg in Figure above is over 10,000 times larger than the mouse cell. Q: What kind of structure contains the largest known single cell? Choices: - proteins - Ovaries - sperm - egg A:
**Answer**
egg
Q: Answer the following question given this paragraph: Q: Some metabolic pathways release what by breaking down complex molecules to simpler compounds? Choices: - fat - hydrogen - water - energy A:
A: energy
