Answer the following question given this paragraph: called an alkaline battery when adapted to operate under alkaline conditions. Button batteries have a high output-to-mass ratio; lithiumiodine batteries consist of a solid electrolyte; the nickel cadmium (NiCad) battery is rechargeable; and the leadacid battery, which is also rechargeable, does not require the electrodes to be in separate compartments. A fuel cell requires an external supply of reactants as the products of the reaction are continuously removed. In a fuel cell, energy is not stored; electrical energy is provided by a chemical reaction. Q: In a fuel cell, energy is not stored; electrical energy is provided by what? Choices: - fusion reaction - carbon reaction - consumption reaction - chemical reaction A:
chemical reaction

Answer the following question given this paragraph: The mouth and stomach are just two of the organs of the digestive system. Other digestive system organs are the esophagus, small intestine, and large intestine. Below, you can see that the digestive organs form a long tube ( Figure below ). In adults, this tube is about 30 feet long! At one end of the tube is the mouth. At the other end is the anus. Food enters the mouth and then passes through the rest of the digestive system. Food waste leaves the body through the anus. Q: The mouth, stomach, esophagus, small intestine, and large intestine are all part of what organ system? Choices: - muscular - respiratory - lymphatic - digestive A:
(Answer)
digestive
Ques: Answer the following question given this paragraph: The skin has multiple roles in the body. Many of these roles are related to homeostasis. The skin's main functions are preventing water loss from the body and serving as a barrier to the entry of microorganisms. In addition, melanin in the skin blocks UV light and protects deeper layers from its damaging effects. Q: The skin plays an important role in preventing the escape of what commonly found liquid from the body? Choices: - hormones - stomach acid - urine - water A:
Ans: water
(Q).
Answer the following question given this paragraph: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Q: Which disease causes cells to divide out of control Choices: - autoimmune diseases - mutation - arthritis - cancer A:
(A).
cancer
Ques:Answer the following question given this paragraph: About 13.7 billion years ago, the entire universe was packed together. Everything was squeezed into a tiny volume. Then there was an enormous explosion. After this "big bang," the universe expanded rapidly ( Figure below ). All of the matter and energy in the universe has been expanding ever since. Scientists have evidence this is how the universe formed. One piece of evidence is that we see galaxies moving away from us. If they are moving apart, they must once have been together. Also, there is energy left over from this explosion throughout the universe. The theory for the origin of the universe is called the Big Bang Theory . Q: The once compressed universe expanded rapidly after what nicknamed event billions of years ago? Choices: - big explosion - good bang - big bust - big bang A:

Ans:big bang
Question: Answer the following question given this paragraph: Then, about 2 or 3 billion years ago, oxygen was gradually added to the atmosphere by early photosynthetic bacteria. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration . Q: Cellular respiration that proceeds in the presence of oxygen is known as what? Choices: - digestive respiration - anaerobic respiration - kinetic respiration - aerobic respiration A:
Answer:
aerobic respiration
