input: OPTIONS:
- protoplasm
- cerebellum
- cytoskeleton
- cytoplasm Now, answer this question: Answer the following question given this paragraph: The Cytoplasm The cytoplasm comprises the contents of a cell between the plasma membrane and the nuclear envelope (a structure to be discussed shortly). It is made up of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals (Figure 3.7). Even though the cytoplasm consists of 70 to 80 percent water, it has a semi-solid consistency, which comes from the proteins within it. However, proteins are not the only organic molecules found in the cytoplasm. Glucose and other simple sugars, polysaccharides, amino acids, nucleic acids, fatty acids, and derivatives of glycerol are found there too. Ions of sodium, potassium, calcium, and many other elements are also dissolved in the cytoplasm. Many metabolic reactions, including protein synthesis, take place in the cytoplasm. Q: What comprises the contents of a cell between the plasma membrane and the nuclear envelope? A:
A:
output: cytoplasm

Answer the following question given this paragraph: Chemical reactions that consume energy are called endothermic reactions . Energy is usually absorbed from the surroundings as heat. An example is the synthesis of ammonia, described above. In organisms, endothermic reactions are called anabolic reactions . Anabolic reactions construct molecules from smaller units. An example is the synthesis of proteins from amino acids. Endothermic reactions can be represented by the general chemical equation:. Q: Chemical reactions that consume energy are called what? A:

OPTIONS:
- exothermic reactions
- inefficient reactions
- greedy reactions
- endothermic reactions

Answer: endothermic reactions

Problem: OPTIONS:
- biochemical transfer
- artificial transfer
- transcription
- genetic transfer
Q: Answer the following question given this paragraph: For natural selection to take place, organisms must vary in their traits. Asexual reproduction results in offspring that are all the same. They are also identical to the parent cell. So how can prokaryotes increase genetic variation? They can exchange plasmids. This is called genetic transfer . It may happen by direct contact between cells. Or a "bridge" may form between cells. Genetic transfer mixes the genes of different cells. It creates new combinations of alleles. Q: What is the exchange of plasmids by prokaryotes called? A:
Answer: genetic transfer

Problem:OPTIONS:
- mushrooms
- yeast
- tropical plants
- fungi

Answer the following question given this paragraph: Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body , which is the part of the fungus that produces spores ( Figure below ). The spores are the basic reproductive units of fungi. The mycelium remains hidden until it develops one or more fruiting bodies. Q: Spores are the basic reproductive units of what organism? A:
****
A: fungi

Answer the following question given this paragraph: What if you were to drop a bowling ball and a soccer ball at the same time from the same distance above the ground? The bowling ball has greater mass than the basketball, so the pull of gravity on it is greater. Would it fall to the ground faster? No, the bowling ball and basketball would reach the ground at the same time. The reason? The more massive bowling ball is also harder to move because of its greater mass, so it ends up moving at the same acceleration as the soccer ball. This is true of all falling objects. They all accelerate at the same rate due to gravity, unless air resistance affects one object more than another. For example, a falling leaf is slowed down by air resistance more than a falling acorn because of the leaf's greater surface area. You can simulate the effect of air resistance on acceleration due to gravity by doing the interactive animation at this URL: http://www. science-animations. com/support-files/freefall. swf. Q: In the absence of air resistance, all falling objects accelerate at the same rate due to what force? A:
OPTIONS:
- velocity
- weight
- motion
- gravity
gravity

Answer the following question given this paragraph: Water is a common chemical substance on planet Earth. In fact, Earth is sometimes called the "water planet" because almost 75% of its surface is covered with water. If you look at Figure below , you will see where Earth's water is found. The term water generally refers to its liquid state, and water is a liquid over a wide range of temperatures on Earth. However, water also occurs on Earth as a solid (ice) and as a gas (water vapor). Q: What is a common chemical substance on planet earth? A:
OPTIONS:
- oxygen
- nitrogen
- hydrogen
- water

Answer:
water
