Answer the following question given this paragraph: Toxic heavy metals include mercury and lead. Mercury is used in some industrial processes. It is also found in fluorescent light bulbs. Lead was once widely used in gasoline, paint, and pipes. It is still found in some products. Q: Mercury and lead, which was once widely used in paint and gasoline, are examples of what type of metals? A:
OPTIONS:
- gaseous heavy metals
- alloys
- sulfuric heavy metals
- toxic heavy metals
toxic heavy metals

Question: Answer the following question given this paragraph: Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s 2 , meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Recall that velocity is a vectorit has both magnitude and direction. This means that a change in velocity can be a change in magnitude (or speed), but it can also be a change in direction. For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both. Acceleration as a Vector Acceleration is a vector in the same direction as the change in velocity, v . Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed or direction, or both. Keep in mind that although acceleration is in the direction of the change in velocity, it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration. Q: Velocity is a vector that has both direction and what? A:
OPTIONS:
- variable
- latitude
- radiation
- magnitude
Answer: magnitude

input with options: Answer the following question given this paragraph: Fossils may form in other ways. With complete preservation, the organism doesn't change much. As seen below, tree sap may cover an organism and then turn into amber. The original organism is preserved so that scientists might be able to study its DNA. Organisms can also be completely preserved in tar or ice. Molds and casts are another way organisms can be fossilized. A mold is an imprint of an organism left in rock. The organism's remains break down completely. Rock that fills in the mold resembles the original remains. The fossil that forms in the mold is called a cast. Molds and casts usually form in sedimentary rock. With compression, an organism's remains are put under great pressure inside rock layers. This leaves behind a dark stain in the rock. Q: A mold is an imprint of an organism left in what? A:
OPTIONS:
- magma
- band
- fossil
- rock
output: rock

Q: Answer the following question given this paragraph: Linnaeus developed binomial nomenclature , a way to give a scientific name to every organism. In this system, each organism receives a two-part name in which the first word is the genus (a group of species), and the second word refers to one species in that genus. For example, a coyote's species name is Canis latrans . Latrans is the species and Canis is the genus, a larger group that includes dogs, wolves, and other dog-like animals. Here is another example: the red maple, Acer rubra , and the sugar maple, Acer saccharum , are both in the same genus and they look similar ( Figure below ). Notice that the genus is capitalized and the species is not, and that the whole scientific name is in italics. Tigers (Panthera tigris) and lions (Panthera leo) have the same genus name, but are obviously different species. The names may seem strange, but the names are written in a language called Latin. Q: Linnaeus developed binomial nomenclature, which means each organism is assigned what? A:

OPTIONS:
- complex name
- simple name
- single name
- two-part name

A: two-part name

Answer the following question given this paragraph: Plants called epiphytes grow on other plants. They obtain moisture from the air and make food by photosynthesis. Most epiphytes are ferns or orchids that live in tropical or temperate rainforests (see Figure below ). Host trees provide support, allowing epiphyte plants to obtain air and sunlight high above the forest floor. Being elevated above the ground lets epiphytes get out of the shadows on the forest floor so they can get enough sunlight for photosynthesis. Being elevated may also reduce the risk of being eaten by herbivores and increase the chance of pollination by wind. Q: What type of plants grow on other plants? A:
OPTIONS:
- bryophytes
- parasites
- legumes
- epiphytes
epiphytes
