Q: Besides tasting food, what organ is necessary for mastication, deglutition (swallowing), and speech? Read this paragraph and choose the correct option from the provided answers: Muscles That Move the Tongue Although the tongue is obviously important for tasting food, it is also necessary for mastication, deglutition (swallowing), and speech (Figure 11.11 and Figure 11.12). Because it is so moveable, the tongue facilitates complex speech patterns and sounds. Choices: - throat - larnyx - mouth - tongue A:
tongue

Q: A symporter carries how many different molecules or ions in the same direction? Read this paragraph and choose the correct option from the provided answers: Figure 5.17 A uniporter carries one molecule or ion. A symporter carries two different molecules or ions, both in the same direction. An antiporter also carries two different molecules or ions, but in different directions. (credit: modification of work by "Lupask"/Wikimedia Commons). Choices: - one - three - four - two A:
two

Q: Q: After cell division what are the two new cells called? Read this paragraph and choose the correct option from the provided answers: Cell division is the process in which a cell divides to form two new cells. The original cell is called the parent cell. The two new cells are called daughter cells. All cells contain DNA. DNA is the nucleic acid that stores genetic information. Before a cell divides its DNA must be copied. That way, each daughter cell gets a complete copy of the parent cell's genetic material. Choices: - offspring cells - production cells - step cells - daughter cells A:
A: daughter cells

Question: Q: During what type of reproduction do two haploid gametes join in the process of fertilization to produce a diploid zygote? Read this paragraph and choose the correct option from the provided answers: During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Choices: - asexual reproduction - essential reproduction - internal reproduction - sexual reproduction A:
Answer: sexual reproduction

Q: Burning fossil fuels produces air pollution and what? Read this paragraph and choose the correct option from the provided answers: Fossil fuelsincluding oil, natural gas, and coalprovide most of the energy used in the world today. Burning fossil fuels produces air pollution as well as carbon dioxide that causes global climate change. Choices: - oxygen - liquid dioxide - acid rain - carbon dioxide A:
**Answer**
carbon dioxide

Q: Q: Aldehydes and ketones can work weak hydrogen bonds with water through what atom? Read this paragraph and choose the correct option from the provided answers: Aldehydes and ketones can work weak hydrogen bonds with water through the carbonyl oxygen atom. The lower members of both series (3 carbons or fewer) are soluble in water in all proportions. As the length of the carbon chain increases, water solubility decreases. Similar to ethers, neither aldehydes nor ketones can hydrogen bond with themselves. As a result, their boiling points are generally lower than those of alcohols. Unlike alkanes however, aldehydes and ketones are polar molecules due to the more electronegative oxygen atom. The dipole-dipole interactions are stronger than the dispersion forces present in alkanes. The boiling points of aldehydes and ketones are intermediate between those of alkanes and alcohols. For example, the boiling point of ethane is -89C, ethanal is 20C, and ethanol is 78C. Choices: - basalt oxygen atom - pyridinium oxygen atom - carbon carbon atom - carbonyl oxygen atom A:
A: carbonyl oxygen atom
