Answer the following question given this paragraph: The information listed at the right of the label tells you what to look for. At the top of the label, look for the serving size. The serving size tells you how much of the food you should eat to get the nutrients listed on the label. A cup of food from the label pictured below is a serving. The calories in one serving are listed next. In this food, there are 250 calories per serving. Q: What tells you how much of the food you should eat to get the nutrients listed on the label? Choices: - regular size - scoop size - longer size - serving size A:
serving size

Answer the following question given this paragraph: So far, we have discussed elements and compounds that are electrically neutral. They have the same number of electrons as protons, so the negative charges of the electrons is balanced by the positive charges of the protons. However, this is not always the case. Electrons can move from one atom to another; when they do, species with overall electric charges are formed. Such species are called ions. Species with overall positive charges are termed cations, while species with overall negative charges are called anions. Remember that ions are formed only when electrons move from one atom to another; a proton never moves from one atom to another. Compounds formed from positive and negative ions are called ionic compounds. Individual atoms can gain or lose electrons. When they do, they become monatomicions. When atoms gain or lose electrons, they usually gain or lose a characteristic number of electrons and so take on a characteristic overall charge. Table 3.6 "Monatomic Ions of Various Charges" lists some common ions in terms of how many electrons they lose (making cations) or gain (making anions). There are several things to notice about the ions in Table 3.6 "Monatomic Ions of Various Charges". First, each element that forms cations is a metal, except for one (hydrogen), while each element that forms anions is a nonmetal. This is actually one of the chemical properties of metals and nonmetals: metals tend to form cations, while nonmetals tend to form anions. Second, most atoms form ions of a single characteristic charge. When sodium atoms form ions, they always form a 1+ charge, never a 2+ or 3+ or even 1 charge. Thus, if you commit the information in Table 3.6 "Monatomic Ions of Various Charges"to memory, you will always know what charges most atoms form. (In Chapter 9 "Chemical Bonds", we will discuss why atoms form the charges they do. ) Table 3.6 Monatomic Ions of Various Charges H+ Na+ K+ Ions formed by losing a single electron. Q: Electrons can move from one atom to another; when they do, specimens called what, with overall electric charges, are formed? Choices: - atoms - molecules - cations - ions A:
(Answer)
ions
Ques: Answer the following question given this paragraph: Scientists classify living things to make sense of biodiversity and who how living things are related. The science of classifying living things is called taxonomy. Q: What is the science of classifying living things is called? Choices: - entomology - methodology - physiology - taxonomy A:
Ans: taxonomy
(Q).
Answer the following question given this paragraph: The immune system protects the body from worms, germs, and other agents of harm. The immune system is like a medieval castle. The outside of the castle was protected by a moat and high stone walls. Inside the castle, soldiers were ready to fight off any invaders that managed to get through the outer defenses. Like a medieval castle, the immune system has a series of defenses. In fact, it has three lines of defense. Only pathogens that are able to get through all three lines of defense can harm the body. Q: What system protects the body from worms, germs, and other agents of harm? Choices: - digestion - hormones - lymph system - immune A:
(A).
immune
Ques:Answer the following question given this paragraph: The electron loss and gain is easy to see in a reaction in which ions are formed. However, in many reactions, no such electron transfer occurs. In a molecular compound, electrons are shared between atoms in a type of bond called a covalent bond. Yet it is still common for reactions involving molecular compounds to still be classified as redox reactions. Q: In a molecular compound, electrons are shared between atoms in which type of bond? Choices: - Ionic - deformation - corrosion - covalent A:

Ans:covalent
Ques:Answer the following question given this paragraph: The parasympathetic division controls involuntary activities that are not emergencies. For example, it controls the organs of your digestive system so they can break down the food you eat. Q: What division of the nervous system controls involuntary activities that are not emergencies, such as the digestive organs breaking down food? Choices: - central nervous system - posterior division - somatic nervous system - parasympathetic division A:

Ans:
parasympathetic division
