Typically the foot has been modified into a set of arms or tentacles. Members of this class can change color. They can also change texture and body shape, and, and if those camouflage techniques don't work, they can still "disappear" in a cloud of ink. Cephalopods have three hearts that pump blue blood, they're jet powered by their muscular foot, and they're found in all oceans of the world. Cephalopods are thought to be the most intelligent of invertebrates. They have eyes and other senses that rival those of humans. Many cephalopods are active and efficient predators. What features do you think allows for this?. Q: Cephalopods have three hearts that pump blood of what color? A:
A:
output: blue

Answer the following question given this paragraph: Plants are the primary producers in terrestrial biomes. They make food for themselves and other organisms by photosynthesis. The major plants in a given biome, in turn, help determine the types of animals and other organisms that can live there. Q: What are the primary producers in terrestrial biomes? A:

OPTIONS:
- soil
- gases
- animals
- plants

Answer: plants

Problem: OPTIONS:
- matter
- frequency
- threshold
- energy
Q: Answer the following question given this paragraph: As you can see in the Figure above , the electric and magnetic fields that make up an electromagnetic wave are perpendicular (at right angles) to each other. Both fields are also perpendicular to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave. However, unlike a mechanical transverse wave, which can only travel through matter, an electromagnetic transverse wave can travel through empty space. When waves travel through matter, they lose some energy to the matter as they pass through it. But when waves travel through space, no energy is lost. Therefore, electromagnetic waves don't get weaker as they travel. However, the energy is "diluted" as it travels farther from its source because it spreads out over an ever-larger area. Q: What may be lost when waves travel through matter, but not when they travel through space? A:
Answer: energy

Problem:OPTIONS:
- rocky vascular plants
- ofen vascular plants
- starchy vascular plants
- seedless vascular plants

Answer the following question given this paragraph: Seedless vascular plants have vascular tissue but do not have seeds. Q: What type of plants have vascular tissue but do not have seeds? A:
****
A: seedless vascular plants

Answer the following question given this paragraph: Solubility is the amount of solute that can dissolve in a given amount of solvent at a given temperature. In a solution, the solute is the substance that dissolves, and the solvent is the substance that does the dissolving. For a given solvent, some solutes have greater solubility than others. For example, sugar is much more soluble in water than is salt. But even sugar has an upper limit on how much can dissolve. In a half liter of 20 C water, the maximum amount is 1000 grams. If you add more sugar than this, the extra sugar won't dissolve. You can compare the solubility of sugar, salt, and some other solutes in the Table below . For a video about solubility, go to this URL: http://www. youtube. com/watch?v=IKimraU21ws . Q: What is the amount of solute that can dissolve in a given amount of solvent at a given temperature? A:
OPTIONS:
- permeability
- humidity
- viscosity
- solubility
solubility

Answer the following question given this paragraph: The parts of the ears involved in balance are the semicircular canals. These are the curved structures above the cochlea in the inner ear in Figure above . Like the cochlea, the semicircular canals contain liquid and are lined with tiny hair cells. As the head changes position, the liquid moves. This causes the hair cells to bend. The bending of the hair cells triggers nerve impulses that travel to the cerebellum in the brain. The cerebellum uses the information to maintain balance. Q: Involved in balance, the semicircular canals are parts of what organs? A:
OPTIONS:
- eyes
- lungs
- ovaries
- ears

Answer:
ears
