input: OPTIONS:
- pressure
- water
- heating
- energy Now, answer this question: Answer the following question given this paragraph: Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion. Q: In passive transport, small molecules or ions move across the cell membrane without requiring input of what? A:
A:
output: energy

Answer the following question given this paragraph: The pioneer species is soon replaced by other populations. Abiotic factors such as soil quality, water, and climate will determine the species that continue the process of succession. Mosses and grasses will be able to grow in the newly created soil. During early succession, plant species like grasses that grow and reproduce quickly will take over the landscape. Over time, these plants improve the soil and a few shrubs can begin to grow. Slowly, the shrubs are replaced by small trees. Small trees then are succeeded by larger trees. Since trees are more successful at competing for resources than shrubs and grasses, a forest may be the end result of primary succession. Q: What's the term for the gradual progression from simple plants to larger more complex ones in an area? A:

OPTIONS:
- complex progression
- pattern progression
- primary pattern
- primary succession

Answer: primary succession

Problem: OPTIONS:
- asteroids
- the sun
- white star
- white dwarf
Q: Answer the following question given this paragraph: A white dwarf is a stellar remnant that is very dense. A white dwarf's mass is comparable to the Sun and its volume is comparable to that of Earth. The very low brightness of a white dwarf comes from the emission of stored heat energy. Q: What is a stellar remnant that is very dense? A:
Answer: white dwarf

Problem:OPTIONS:
- light energy
- radioactivity
- harmonic energy
- kinetic energy

Answer the following question given this paragraph: Heat expansion is a result of the increase of kinetic energy of the molecules. As their movement increases, they bump into each other more and the material slightly expands as a result. Most materials expand with heat. Water is a particularly interesting substance in that it contracts as its temperature increases from to (and then expands from to ). Q: Heat expansion is a result of the increase of what type of energy, exhibited by molecules bumping together? A:
****
A: kinetic energy

Answer the following question given this paragraph: Translation is the RNA protein part of the central dogma. It occurs at a ribosome. During translation, a protein is synthesized using the codons in mRNA as a guide. All three types of RNA play a role in translation. Q: What exactly happens during rna translation? A:
OPTIONS:
- carbohydrate is synthesized
- membrane is synthesized
- chromosome is synthesized
- protein is synthesized
protein is synthesized

Answer the following question given this paragraph: Q: In multicellular organisms, only mutations in cell lines that produce gametes can be passed to what? A:
OPTIONS:
- cells
- clones
- proteins
- offspring

Answer:
offspring
