Q: Answer the following question given this paragraph: Chromosomal alterations are mutations that change chromosome structure. They occur when a section of a chromosome breaks off and rejoins incorrectly or does not rejoin at all. Possible ways these mutations can occur are illustrated in Figure below . Go to this link for a video about chromosomal alterations: http://www. youtube. com/watch?v=OrXRSqa_3lU (2:18). Q: Chromosomal alterations are mutations that change what? Choices: - Skeleton Structure - detected structure - discovery structure - chromosome structure A:
A: chromosome structure

Q: Answer the following question given this paragraph: Scientists use models to help them understand and explain ideas. Models explain objects or systems in a more simple way. Models often only show only a part of a system. The real situation is more complicated. Models help scientists to make predictions about complex systems. Some models are something that you can see or touch. Other types of models use an idea or numbers. Each type is useful in certain ways. Q: What do scientists use to help explain objects or systems in simpler ways? Choices: - theories - measurements - plants - models A:
A: models

A: liquid or gas

Q: Answer the following question given this paragraph: The specific heat capacity (c) of a substance, commonly called its "specific heat," is the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius (or 1 kelvin): q c= mT Specific heat capacity depends only on the kind of substance absorbing or releasing heat. It is an intensive propertythe type, but not the amount, of the substance is all that matters. For example, the small cast iron frying pan has a mass of 808 g. The specific heat of iron (the material used to make the pan) is therefore: c iron =. Q: What is the term for the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius? Choices: - thermal heat capacity - transferable heat - heat requirement - specific heat capacity A:
A: specific heat capacity
