Answer the following question given this paragraph: Pluto was different in other ways. The outer planets are all gas giants. Pluto is small, icy, and rocky. Pluto has a diameter of about 2,400 km. It has only about one-fifth the mass of Earth's Moon. Pluto's orbit is tilted relative to the other planets. It's orbit is shaped like a long, narrow ellipse. Pluto's orbit sometimes even passes inside Neptune's orbit. Q: What, now former, planet is small, icy, and rocky? Choices: - mercury - jupiter - neptune - pluto A:
pluto

Answer the following question given this paragraph: An insect's abdomen contains most of the internal organs. Like other arthropods, insects have a complete digestive system. They also have an open circulatory system and central nervous system. Like other terrestrial arthropods, they have trachea for breathing air and Malphigian tubules for excretion. Q: Where are more of an insect's internal organs kept? Choices: - the head - the thorax - the chest cavity - the abdomen A:
(Answer)
the abdomen
Ques: Answer the following question given this paragraph: Heat and light are forms of energy. Other forms are chemical and electrical energy. Energy can't be created or destroyed. It can change form. For example, a piece of wood has chemical energy stored in its molecules. When the wood burns, the chemical energy changes to heat and light energy. Q: How do plants support themselves above the ground to get light and oxygen? Choices: - momentum - flaccid stems - symbiosis - stiff stems A:
Ans: stiff stems
(Q).
Answer the following question given this paragraph: Humans could not live on Earth if it were not for protists. Why? Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. All protists make up a huge part of the food chain. Q: What produces almost one-half of the earth's oxygen through photosynthesis? Choices: - prokaryotes - algae - arthropods - protists A:
(A).
protists
Ques:Answer the following question given this paragraph: Crocodilia, containing both alligators and crocodiles, is an order of large reptiles. Reptiles belonging to Crocodilia are the closest living relatives of birds. Reptiles and birds are the only known living descendants of the dinosaurs. Some would day that alligators and crocodiles actually look like small dinosaurs. Dinosaurs that evolved wings are the ancestors of birds. Q: Reptiles and birds are the only known living descendants of what? Choices: - mammals - fossils - dragons - dinosaurs A:

Ans:dinosaurs
Question: Answer the following question given this paragraph: Why do charges flow in an electric current? The answer has to do with electric potential energy. Potential energy is stored energy that an object has due to its position or shape. An electric charge has potential energy because of its position in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where their potential energy is lower. This is similar to water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What is the scientific term for stored energy an object has due to its position or shape? Choices: - repeat energy - mechanical energy - new energy - potential energy A:
Answer:
potential energy
