Q: Answer the following question given this paragraph: Herbivores such as zebras and elephants live in herds . Adults in the herd surround and protect the young, who are most vulnerable to predators. Q: Why do adult herbivores in a herd surround their young? A:
Answer: to protect them as they are vulnerable to predators

Problem:OPTIONS:

- bacterial plants
- aquatic plants

Answer the following question given this paragraph: Modern plants that live in water are called aquatic plants . Living in water has certain advantages for plants. One advantage is, well, the water. There's plenty of it and it's all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticle on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants. Q: What type of plants do not typically require deep roots or woody stems? A:
****
A: aquatic plants

Answer the following question given this paragraph: Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the oxygen atoms in the Figure above . Alone, each oxygen atom has six valence electrons. By sharing two pairs of valence electrons, each oxygen atom has a total of eight valence electrons. This fills its outer energy level, giving it the most stable arrangement of electrons. The shared electrons are attracted to both oxygen nuclei, and this force of attraction holds the two atoms together in the oxygen molecule. Q: What do covalent bonds give atoms a more stable arrangement of? A:
OPTIONS:
- protons
- neutrons
- cell walls
- electrons
electrons

Answer the following question given this paragraph: This super fast train can obviously reach great speeds. And there's a lot of technology that helps this train go fast. Speaking of helping things go fast brings us to enzymes. Life could not exist without enzymes. Essentially, enzymes are biological catalysts that speed up biochemical reactions. Q: What are biological catalysts that speeds up biochemical reactions? A:
OPTIONS:
- carbohydrates
- hormones
- proteins
- enzymes

Answer: enzymes

Question: Answer the following question given this paragraph: Supercritical Fluids If we place a sample of water in a sealed container at 25 C, remove the air, and let the vaporization-condensation equilibrium establish itself, we are left with a mixture of liquid water and water vapor at a pressure of 0.03 atm. A distinct boundary between the more dense liquid and the less dense gas is clearly observed. As we increase the temperature, the pressure of the water vapor increases, as described by the liquid-gas curve in the phase diagram for water (Figure 10.31), and a two-phase equilibrium of liquid and gaseous phases remains. At a temperature of 374 C, the vapor pressure has risen to 218 atm, and any further increase in temperature results in the disappearance of the boundary between liquid and vapor phases. All of the water in the container is now present in a single phase whose physical properties are intermediate between those of the gaseous and liquid states. This phase of matter is called a supercritical fluid, and the temperature and pressure above which this phase exists is the critical point (Figure 10.35). Above its critical temperature, a gas cannot be liquefied no matter how much pressure is applied. The pressure required to liquefy a gas at its critical temperature is called the critical pressure. The critical temperatures and critical pressures of some common substances are given in Table 10.3. Substance. Q: What phase exists when all the water in a container has physical properties intermediate between those of the gaseous and liquid states? A:
OPTIONS:
- stationary fluid
- hydrothermal fluid
- impregnation fluid
- supercritical fluid
Answer: supercritical fluid
