Answer the following question given this paragraph: Potential energy due to the position of an object above Earth is called gravitational potential energy. Like the leaves on trees, anything that is raised up above Earth's surface has the potential to fall because of gravity. You can see examples of people with gravitational potential energy in Figure below . Q: What is the term for potential energy due to the position of an object above earth? Choices: - gravitational pull energy - gravitational indication energy - gravitational recovery energy - gravitational potential energy A:
gravitational potential energy

Answer the following question given this paragraph: Not getting enough vitamins can cause health problems. For example, too little vitamin C causes a disease called scurvy. People with scurvy have bleeding gums, nosebleeds, and other symptoms. Q: What disease, caused by vitamin c deficiency, causes bleeding gums, nosebleeds, and other symptoms? Choices: - rickets - dehydration - leukemia - scurvy A:
(Answer)
scurvy
Ques: Answer the following question given this paragraph: Some lipids contain the element phosphorus as well as carbon, hydrogen, and oxygen. These lipids are called phospholipids. Two layers of phospholipid molecules make up the cell membranes of living things. In the Figure below , you can see how phospholipid molecules are arranged in a cell membrane. Q: What type of lipids contain the element phosphorus, carbon, hydrogen and oxygen? Choices: - filaments - eukaryotes - alleles - phospholipids A:
Ans: phospholipids

Answer the following question given this paragraph: Conceptual Questions 33.3 Accelerators Create Matter from Energy 1. The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle? 2. Synchrotron radiation takes energy from an accelerator beam and is related to acceleration. Why would you expect the problem to be more severe for electron accelerators than proton accelerators? 3. What two major limitations prevent us from building high-energy accelerators that are physically small? 4. What are the advantages of colliding-beam accelerators? What are the disadvantages?. Q: Colliding-beam accelerators create matter from what? Choices: - magnetism - sound - minerals - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: Tropical climates are found around the Equator. As you'd expect, these climates have warm temperatures year round. The warm air rises at the Equator. As it rises, it cools, causing it to rain. Tropical climates may be very wet, or wet and dry. Q: What type of climates are found around the equator? Choices: - arid - tundras - arctics - tropical A:

Ans:tropical
Question: Answer the following question given this paragraph: At the end of the Cretaceous Period, or 65 million years ago, all dinosaurs (except those which led to birds) went extinct. Some scientists believe a possible cause is a collision between the Earth and a comet or asteroid. The collision could have caused tidal waves, changed the climate, increased atmospheric dust and clouds, and reduced sunlight by 10-20%. A decrease in photosynthesis would have resulted in less plant food, leading to the extinction of the dinosaurs. Q: All dinosaurs (except those which led to birds) went extinct at the end of which period? Choices: - Tertiary - Jurassic - Paleogene - cretaceous A:
Answer:
cretaceous
