Answer the following question given this paragraph: An aldehyde is a carbonyl in which the carbon atom is bonded to one carbon atom and one hydrogen atom (or two hydrogen atoms, see below). Because the hydrogen atom is so small, the partial positive charge on the carbonyl carbon is very easy for other molecules to approach, making aldehydes a particularly reactive type of carbonyl. Aldehydes are versatile reactants for a wide variety of organic syntheses. Many aldehydes also have distinctive flavors and aromas. For example, the flavor of cinnamon is primarily due to the molecule cinnamaldehyde, and vanillin is the aldehyde most responsible for the smell and taste of vanilla extract. Q: Name a carbonyl in which the carbon atom is bonded to one carbon atom and one hydrogen atom (or two hydrogen atoms). Choices: - ketone - acetylcholine - ester - aldehyde A:
aldehyde
Answer the following question given this paragraph: This model shows the arrangement of oxygen and hydrogen atoms in a water molecule. A water molecule has a bent or angular (non-linear) shape, with an angle of about 105. The nucleus of the oxygen atom attracts electrons more strongly than do the hydrogen nuclei. As a result, the middle part of the molecule near oxygen has a negative charge, and the other parts of the molecule have a positive charge. In essence, the electrons are "pulled" toward the nucleus of the oxygen atom and away from the hydrogen atom nuclei. Water is a polar molecule, with an unequal distribution of charge throughout the molecule. Q: The oxygen atom in a water molecule pull the electrons away from the hydrogen atoms which leads to an unequal distribution of what? Choices: - nitrogen - atomic mass - orbits - charge A:
charge
Q: Answer the following question given this paragraph: Earth science includes many fields of science related to our home planet. Q: What science includes many fields of science related to our home planet? Choices: - meteorology - zoology - biology - earth science A:
A: earth science
Question: Answer the following question given this paragraph: The components of a mixture keep their own identity when they combine. Therefore, they usually can be easily separated again. Their different physical properties are used to separate them. For example, oil is less dense than water, so a mixture of oil and water can be separated by letting it stand until the oil floats to the top. Other ways of separating mixtures are shown in Figure below and in the videos below. Q: The components of what keep their own identity when they combine and can usually be easily separated? Choices: - alloy - solution - compound - mixture A:
Answer: mixture

Answer the following question given this paragraph: This equation for kinetic energy shows that velocity affects kinetic energy more than mass does. For example, if mass doubles, kinetic energy also doubles. But if velocity doubles, kinetic energy increases by a factor of four. That's because velocity is squared in the equation. You can see for yourself how mass and velocity affect kinetic energy by working through the problems below. Q: Velocity affects what type of energy more than mass does? Choices: - magnetic energy - harmonic energy - mechanical energy - kinetic energy A:
**Answer**
kinetic energy

Answer the following question given this paragraph: In most species, one or both parents take care of the eggs. They sit on the eggs to keep them warm until they hatch. This is called incubation. After the eggs hatch, the parents generally continue their care. They feed the hatchlings until they are big enough to feed on their own. This is usually at a younger age in ground-nesting birds such as ducks than in tree-nesting birds such as robins. Q: When animals use incubation, how do they generally give birth to their young? Choices: - copying - live - division - eggs A:
(Answer)
eggs
