Answer the following question given this paragraph: Give examples of energy conversions between potential and kinetic energy. Q: Two important types of energy that can be converted to one another include potential and what? Choices: - physical - thermal - magnetic - kinetic A:
kinetic
Answer the following question given this paragraph: Birds live in a variety of different habitats. Birds that live in different habitats will encounter different foods and different predators. Birds can be carnivores (feeding on other animals), herbivores (feeding on plants), or generalists (feeding on a variety of foods). The lifestyle of the bird can affect what it looks like. For example, can you think of some examples of beaks that are adapted to the type of food a bird eats? Carnivorous birds include hawks, falcons, eagles, osprey, vultures and owls. Herbivorous birds include the goose, cockatoo and parrot. The American Crow is an example of a generalist. In addition, a specialist is a bird (or other animal) that is specially adapted to eat a certain food. An example of a specialist is a hummingbird, whose long, thin beak is excellent for reaching into flowers for nectar, but not very good for eating other foods. Q: What do you call an animal that feeds on other animals? Choices: - omnivore - herbivore - polyvore - carnivore A:
carnivore
Q: Answer the following question given this paragraph: Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins. A transport protein completely spans the membrane, and allows certain molecules or ions to diffuse across the membrane. Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion. Q: Due to the __________ nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot easily diffuse across the cell membrane. Choices: - hydrophylic - saturated - catalytic - hydrophobic A:
A: hydrophobic
Question: Answer the following question given this paragraph: Much of Earth's surface is covered with oceans. That's why Earth is called the "water planet. " Without all that water, Earth would be a very different place. The oceans affect Earth's atmosphere and influence its climate. An incredible diversity of living things inhabit the ocean as well. You might think that oceans have always covered Earth's surface, but you would be wrong!. Q: The oceans affect earth's atmosphere and influence its what? Choices: - earthquakes - mountains - volcanoes - climate A:
Answer: climate

Answer the following question given this paragraph: Cleavage is the tendency of a mineral to break along certain planes. When a mineral breaks along a plane it makes a smooth surface. Minerals with different crystal structures will break or cleave in different ways, as in Figure below . Halite tends to form cubes with smooth surfaces. Mica tends to form sheets. Fluorite can form octahedrons. Q: What term means the tendency of a mineral to break along certain planes? Choices: - cavity - fault - fracture - cleavage A:
**Answer**
cleavage

Answer the following question given this paragraph: Circadian rhythms are regular changes in biology or behavior that occur in a 24-hour cycle. In humans, for example, blood pressure and body temperature change in a regular way throughout each 24-hour day. Animals may eat and drink at certain times of day as well. Humans have daily cycles of behavior, too. Most people start to get sleepy after dark and have a hard time sleeping when it is light outside. In many species, including humans, circadian rhythms are controlled by a tiny structure called the biological clock . This structure is located in a gland at the base of the brain. The biological clock sends signals to the body. The signals cause regular changes in behavior and body processes. The amount of light entering the eyes helps control the biological clock. The clock causes changes that repeat every 24 hours. Q: What do you call the regular changes in biology or behavior that occur in a 24-hour cycle? Choices: - cognitive rhythms - variable rhythms - sleep rhythms - circadian rhythms A:
**Answer**
circadian rhythms
