 Answer: more ribosomes
Output: The folds present in the membrane increase the surface area allowing more ribosomes to be present on the ER, thereby allowing greater protein production.
Question: The closer to sea level that you get the 
 Answer: warmer it is
Output: The surface is heated by the Sun and some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes.
Question: John is relaxing at the beach watching the waves when the wind begins to pick up. When the wind begins to blow faster, what happens to the size of the waves? 
 Answer: increase
Output: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be.

 Answer: Lesser
Output: With fewer trees, the air is drier and droughts are more common.
Question: Compared to an obese person who has never exercised, would an Olympic sprinter in perfect condition be more likely to have a heart that can, with each beat, move 
 Answer: more blood
Output: When a person exercises regularly, and is fit, the heart undergoes certain long-term adaptations. The heart muscle gets stronger, and expels more blood with each contraction.

 Answer: lower
Output: The density of the atmosphere decreases with an increase in the height above sea level (altitude).
Question: If Milo makes an effort to use less resources in his day to day life, what will happen to the amount of waste he produces? 
 Answer: decrease
Output: Increased resource use generally means more waste; electronic waste from developed nations is a growing problem in the developing world.

 Answer: more
Output: The more the baby suckles, the more prolactin is released, which causes more milk to be produced.
Question: What will happen to the effect on ocean tides if the Moon were to move farther to the Earth? 
 Answer: smaller effect
Output: The Moon has a greater effect on the tides because, although it is much smaller than the Sun, it is much closer.
Question: When quarks are brought together, they experience minimal attraction, but when they're taken further apart, they have an attraction that is 
 Answer: greater
Output: Gluons make quarks attract each other more strongly the farther apart the quarks get.
Question: What happens to the rate at which waves move past a particular spot if Jim increases the wavelength of a sound wave? 
 Answer: decreases
Output: This means that as wavelengths get shorter, more waves move past a particular spot in the same amount of time.
Question: Will is one year old and breastfeeds from his mother. He suckles more and more. The mother produces _____ milk in response. 
 Answer: more
Output: The more the baby suckles, the more prolactin is released, which causes more milk to be produced.
Question: If Milo is playing with his rubber bands and he stretches one out, what can he expect to happen to the resistance as he stretches it tighter? 
 Answer: increase
Output: The farther you stretch the band, the greater the resistance is.
Question: If Jimbo decreases the wavelength of the soundwave he is generating, what will happen to the energy carried by that soundwave? 
 Answer: increases
Output: Waves with shorter wavelengths have more energy.
Question: Sara is in a container representing an object. Her container has 30 balls flying around, representing particles. Tyler is in another container, and his contains 5 balls. Which person's container likely would be under the most pressure? 
 Answer: Sara's
Output: More particles inside the container means more collisions, and more collisions mean a higher pressure.
Question: Rita added less food to the box. It is now _____ to move. 
 Answer: easier
Output: The full box is harder to move because it has greater mass and therefore greater inertia.
Question: A population of squirrels in a local forest had more food available to them this spring than they did last spring. During which spring will more squirrels leave the area to live somewhere else? 
 Answer: last spring
Output: Low food supply or a lack of space can lower birth rates, increase death rates, or lead to emigration.

 Answer: decreases it
Output: The full box is harder to move because it has greater mass and therefore greater inertia.
Question: What happens when you make a rocket heavier? 
 Answer: falls down
Output: By using multiple stages, empty fuel containers could drop away. This reduced the mass of the rocket so that it could fly higher.
