Answer the following question given this paragraph: In polar covalent bonds, electrons are not shared equally between the two atoms, so one atom is slightly negative in charge and one is slightly positive in charge. In nonpolar covalent bonds, electrons are shared equally so the atoms remain neutral in charge. Q: Electrons are not shared equally between the two atoms in which type of covalent bonds? A:
OPTIONS:
- wide
- narrow
- solar
- polar
polar

They were the only living things until the first eukaryotic cells evolved about 2 billion years ago. Prokaryotes are still the most numerous organisms on Earth. Q: What were the first living things to evolve on earth? A:
OPTIONS:
- eukaryotes
- carbon

Answer: prokaryotes

input with options: Answer the following question given this paragraph: How does sap get to the tops of tall trees? (Recall that a column of water can only rise to a height of 10 m when there is a vacuum at the topsee Example 11.5. ) The question has not been completely resolved, but it appears that it is pulled up like a chain held together by cohesive forces. As each molecule of sap enters a leaf and evaporates (a process called transpiration), the entire chain is pulled up a notch. So a negative pressure created by water evaporation must be present to pull the sap up through the xylem vessels. In most situations, fluids can push but can exert only negligible pull, because the cohesive forces seem to be too small to hold the molecules tightly together. But in this case, the cohesive force of water molecules provides a very strong pull. Figure 11.36 shows one device for studying negative pressure. Some experiments have demonstrated that negative pressures sufficient to pull sap to the tops of the tallest trees can be achieved. Q: How does sap get to the tops of tall trees? A:
OPTIONS:
- through suction power
- via Coriolis forces
- through pressure from below
- through negative pressure
output: through negative pressure

Q: Answer the following question given this paragraph: Innate behaviors occur in all animals. However, they are less common in species with higher levels of intelligence. Humans are the most intelligent species, and they have very few innate behaviors. The only innate behaviors in humans are reflexes. A reflex is a response that always occurs when a certain stimulus is present. For example, a human infant will grasp an object, such as a finger, that is placed in its palm. The infant has no control over this reaction because it is innate. Other than reflexes such as this, human behaviors are learnedor at least influenced by experiencerather than being innate. Q: Innate behaviors occur in all animals. however, they are less common in species with higher levels of what? A:

OPTIONS:
- hormones
- interdependence
- nonverbal communication
- intelligence

A: intelligence
