Q: Answer the following question given this paragraph: The area of a surface is how much space it covers. It's easy to calculate the area of a surface if it has a regular shape, such as the blue rectangle in the sketch below. You simply substitute measurements of the surface into the correct formula. To find the area of a rectangular surface, use this formula:. Q: How much space a surface covers is known as what? A:

OPTIONS:
- Flatness
- Lenght
- Height
- area

A: area

input: OPTIONS:
- spontaneous mutation
- adaptation
- variation
- evolution Now, answer this question: Answer the following question given this paragraph: The term evolution describes the changes that occur in populations of living organisms over time. Describing these changes does not address the origin of life. The two are commonly and mistakenly confused. Biological evolution likewise says nothing about cosmology, the Big Bang, or where the universe, galaxy, solar system, or Earth came from. Q: What process refers to the changes that occur in populations of living organisms over time? A:
A:
output: evolution

Answer the following question given this paragraph: Herbivores eat plants, carnivores eat meat, and omnivores eat both. Q: What do herbivores eat? A:

OPTIONS:
- minerals
- meat and plants
- animals
- plants

Answer: plants

Problem: OPTIONS:
- left atrium
- left ventricle
- right ventricle
- right atrium
Q: Answer the following question given this paragraph: Figure 40.10 The mammalian circulatory system is divided into three circuits: the systemic circuit, the pulmonary circuit, and the coronary circuit. Blood is pumped from veins of the systemic circuit into the right atrium of the heart, then into the right ventricle. Blood then enters the pulmonary circuit, and is oxygenated by the lungs. From the pulmonary circuit, blood re-enters the heart through the left atrium. From the left ventricle, blood re-enters the systemic circuit through the aorta and is distributed to the rest of the body. The coronary circuit, which provides blood to the heart, is not shown. Q: What part of the heart receives the blood is pumped from veins of the systemic circuit? A:
Answer: right atrium

Problem:OPTIONS:
- magnitude
- frequency
- voltage
- amplitude

Answer the following question given this paragraph: In a longitudinal wave, amplitude is a measure of how compressed particles of the medium become when the wave passes through. The closer together the particles are, the greater the amplitude. Q: In a longitudinal wave, what term is a measure of how compressed particles of the medium become when the wave passes through? A:
****
A: amplitude

Problem:OPTIONS:
- cell membrane
- umbilicus
- umbilical sac
- amniotic sac

Answer the following question given this paragraph: The amniotic sac is a membrane that surrounds the fetus. It is filled with water and dissolved substances, known as amniotic fluid. Imagine placing a small plastic toy inside a balloon and then filling the balloon with water. The toy would be cushioned and protected by the water. It would also be able to move freely inside the balloon. The amniotic sac and its fluid are like a water-filled balloon. They cushion and protect the fetus. They also let the fetus move freely inside the uterus. Q: What is the membrane that surrounds a fetus called? A:
****
A:
amniotic sac
