Ques:Answer the following question given this paragraph: Centrioles are rod-like structures made of short microtubules. Nine groups of three microtubules make up each centriole. Two perpendicular centrioles make up the centrosome . Centrioles are very important in cellular division, where they arrange the mitotic spindles that pull the chromosome apart during mitosis. Q: What are the rod-like structures made of short microtubules that play an important part in cellular division? Choices: - cilia - mitochondria - fibrils - centrioles A:

Ans:centrioles

Ques:Answer the following question given this paragraph: In this equation, two substances combine to make a single substance. This is a composition reaction. Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction. A single substance reacts to make multiple substances. This is a decomposition reaction. Q: What type of reaction causes two substances to combine to make a single substance? Choices: - component reaction - spontaneous mutation - metabolism - composition reaction A:

Ans:composition reaction

Ques:Answer the following question given this paragraph: Flat Bones The term " flat bone" is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs. Q: What type of bones serve as points of attachment for muscles and often protect internal organs? Choices: - sesamoid bones - irregular bones - short bones - flat bones A:

Ans:flat bones

Ques:Answer the following question given this paragraph: Solutions may be prepared in which a solute concentration exceeds its solubility. Such solutions are said to be supersaturated, and they are interesting examples of nonequilibrium states. For example, the carbonated beverage in an open container that has not yet "gone flat" is supersaturated with carbon dioxide gas; given time, the CO2 concentration will decrease until it reaches its equilibrium value. Q: Solutions that are prepared in which a solute concentration exceeds its solubility are called what? Choices: - solidified - instantiated - mineralized - supersaturated A:

Ans:
supersaturated
