Answer the following question given this paragraph: Introduction All living organisms need nutrients to survive. While plants can obtain the molecules required for cellular function through the process of photosynthesis, most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular functions, such as assembling new molecules, cells, and tissues. The conversion of the food consumed to the nutrients required is a multi-step process involving digestion and absorption. During digestion, food particles are broken down to smaller components, and later, they are absorbed by the body. Q: Plants obtain the molecules for cellular function though what? Choices: - tissues - nutrients - Plants - photosynthesis A:
photosynthesis

Answer the following question given this paragraph: Allergies occur when the immune system makes an inflammatory response to a harmless antigen. An antigen that causes an allergy is called an allergen. Q: What occurs when the immune system makes an inflammatory response to a harmless antigen? Choices: - antibodies - asthma attack - immunity - allergies A:
(Answer)
allergies
Ques: Answer the following question given this paragraph: Telescopes on Earth all have one big problem: incoming light must pass through the atmosphere. This blocks some wavelengths of radiation. Also, motion in the atmosphere distorts light. You see this when you see stars twinkling in the night sky. Many observatories are built on high mountains. There is less air above the telescope, so there is less interference from the atmosphere. Space telescopes avoid problems from the atmosphere completely since they orbit outside the atmosphere. Q: Many observatories are built on high mountains to avoid interference from what? Choices: - airplanes - artificial light - animal life - the atmosphere A:
Ans: the atmosphere
(Q).
Answer the following question given this paragraph: An acid-base reaction according to the Brnsted-Lowry definition is a transfer of a proton from one molecule or ion to another. When ammonia is dissolved in water, it undergoes the following reversible reaction. Q: What type of reaction is a transfer of a proton from one molecule or ion to another? Choices: - ionic bonding - thermal reaction - ionization - acid-base A:
(A).
acid-base
Ques:Answer the following question given this paragraph: Glycogen Glycogen is the energy reserve carbohydrate of animals. Practically all mammalian cells contain some stored carbohydrates in the form of glycogen, but it is especially abundant in the liver (4%8% by weight of tissue) and in skeletal muscle cells (0.5%1.0%). Like starch in plants, glycogen is found as granules in liver and muscle cells. When fasting, Saylor URL: http://www. saylor. org/books. Q: What term is used to describe the energy reserve carbohydrate of animals? Choices: - lactose - fructose - sucrose - glycogen A:

Ans:glycogen
