Answer the following question given this paragraph: Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp (see Figure below ). The nearly blind shrimp and the fish spend most of their time together. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone. From their relationship, the shrimp gets a warning of approaching danger. The fish gets a safe retreat and a place to lay its eggs. Q: What is a symbiotic relationship in which both species benefit? Choices: - detrimental - parasitism - inorganic - mutualism A:
mutualism

Answer the following question given this paragraph: Arthropods range in length from about 1 millimeter (0.04 inches) to 4 meters (about 13 feet). They have a segmented body with a hard exoskeleton. They also have jointed appendages. The body segments are the head, thorax, and abdomen (see Figure below ). In some arthropods, the head and thorax are joined together as a cephalothorax. Q: The head, thorax, and abdomen comprise what type of body structure, possessed by arthropods? Choices: - vertebrate - elongated - permeable - segmented A:
(Answer)
segmented
Ques: Answer the following question given this paragraph: Cow manure can have a second life as a source of methane gas, which can be converted to electricity. Not only that food scraps can also be converted into green energy. Q: Cow manure can have a second life as a source of what gas? Choices: - freon - hydrogen - ethanol - methane A:

(Q).
Answer the following question given this paragraph: In alcoholic fermentation, glycolysis is followed by a step that produces alcohol and carbon dioxide. This step also forms additional molecules of ATP. It occurs in yeast, such as the yeast in bread. Carbon dioxide from alcoholic fermentation creates gas bubbles in bread dough. The bubbles leave little holes in the bread after it bakes. You can see them in the bread in Figure below . The holes make the bread light and fluffy. Q: Bubbles in bread dough are created by what gas produced during alcoholic fermentation? Choices: - acid dioxide - combustion dioxide - yeast dioxide - carbon dioxide A:
(A).
carbon dioxide
Ques:Answer the following question given this paragraph: Many adults and some children suffer from a deficiency of lactase. These individuals are said to be lactose intolerant because they cannot digest the lactose found in milk. A more serious problem is the genetic disease galactosemia, which results from the absence of an enzyme needed to convert galactose to glucose. Certain bacteria can metabolize lactose, forming lactic acid as one of the products. This reaction is responsible for the "souring" of milk. Q: Many adults and some children suffer from a deficiency of lactase. these individuals are said to be lactose intolerant because they cannot digest the lactose found in what? Choices: - fruit - peanuts - meat - milk A:

Ans:milk
