Answer the following question given this paragraph: What is the difference between a trait and a genetic disorder ? Could a disorder be considered a trait? We tend to think of traits as hair color or skin color and disorders as something that is bad for you. But in terms of genetics, a genetic disorder is a trait. Both may be due to your genes. Traits may be inherited in any of a number of ways: autosomal dominant or recessive, sex-linked inheritance, or a more complex pattern of inheritance. Q: Hair color and skin color are known as what? Choices: - habits - abominations - mutations - traits A:
(Answer)

Ques: Answer the following question given this paragraph: A compound has different properties than the substances it contains. For example, hydrogen and oxygen are gases at room temperature. But when they combine chemically, they form liquid water. Another example is table salt, or sodium chloride. It contains sodium and chlorine. Sodium is a silvery solid that reacts explosively with water, and chlorine is a poisonous gas (see Figure below ). But together, sodium and chlorine form a harmless, unreactive compound that you can safely sprinkle on food. Q: In what form of matter is hydrogen at room temperature? Choices: - dissolved - liquid - solid - gas A:
Ans: gas

Question: Answer the following question given this paragraph: Two forces may act on an object in the same direction. You can see an example of this in Figure below . After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces alone. In this case, the net force on the couch is 45 newtons to the right, so the couch will move to the right. Q: What is the net force when two forces act in the same direction? Choices: - number of the forces - arguing forces - group of forces - sum of the forces A:
Answer:
sum of the forces
