Q: Answer the following question given this paragraph: Only certain materials, called ferromagnetic materials, can be magnetized. They include iron, cobalt, and nickel. Materials that have been magnetized may become temporary or permanent magnets. Q: What are materials that can be magnetized called? Choices: - catalytic materials - interstitial materials - Metal material - ferromagnetic materials A:
A: ferromagnetic materials

Q: Answer the following question given this paragraph: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations . They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two:. Q: Mutations which benefit the organism in which they occur are known as? Choices: - extraordinary mutations - helpful mutations - healthy mutations - beneficial mutations A:
A: beneficial mutations

Q: Answer the following question given this paragraph: Reactivity is how likely an element is to react chemically with other elements. Some nonmetals are extremely reactive, whereas others are completely nonreactive. What explains this variation in nonmetals? The answer is their number of valence electrons. These are the electrons in the outer energy level of an atom that are involved in interactions with other atoms. Let's look at two examples of nonmetals, fluorine and neon. Simple atomic models of these two elements are shown in the Figure below . Q: The number of valence electrons determines variation of what property in nonmetals? Choices: - permeability - density - turbidity - reactivity A:
A: reactivity

Q: Answer the following question given this paragraph: Superior Rotation and Inferior Rotation Superior and inferior rotation are movements of the scapula and are defined by the direction of movement of the glenoid cavity. These motions involve rotation of the scapula around a point inferior to the scapular spine and are produced by combinations of muscles acting on the scapula. During superior rotation, the glenoid cavity moves upward as the medial end of the scapular spine moves downward. This is a very important motion that contributes to upper limb abduction. Without superior rotation of the scapula, the greater tubercle of the humerus would hit the acromion of the scapula, thus preventing any abduction of the arm above shoulder height. Superior rotation of the scapula is thus required for full abduction of the upper limb. Superior rotation is also used without arm abduction when carrying a heavy load with your hand or on your shoulder. You can feel this rotation when you pick up a load, such as a heavy book bag and carry it on only one shoulder. To increase its weight-bearing support for the bag, the shoulder lifts as the scapula superiorly rotates. Inferior rotation occurs during limb adduction and involves the downward motion of the glenoid cavity with upward movement of the medial end of the scapular spine. Q: Inferior rotation occurs during limb adduction and involves the downward motion of what? Choices: - choroidal cavity - pelvic cavity - dialysate cavity - glenoid cavity A:
A: glenoid cavity
