Answer the following question given this paragraph: The concentration of hydronium ions in a solution is known as acidity . In pure water, the concentration of hydronium ions is very low; only about 1 in 10 million water molecules naturally breaks down to form a hydronium ion. As a result, pure water is essentially neutral. Acidity is measured on a scale called pH , as shown in Figure below . Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Q: The concentration of hydronium ions in a solution is known as what? Choices: - base - akaline - pH value - acidity A:
(Answer)
acidity
Ques: Answer the following question given this paragraph: That may depend on the plant. Start with moss. The typical nonvascular plant. But such a simple plant has a very interesting life cycle. Whereas most kinds of plants have two sets of chromosomes in their vegetative cells, mosses have only a single set of chromosomes. So, how does meiosis occur?. Q: How many set of chromosomes do moss have? Choices: - double set - triple set - none - single set A:
Ans: single set

Answer the following question given this paragraph: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactionschemical reactions catalyzed by enzymesbegin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate. Q: What is the name of a reactant in an enzymatic reaction? Choices: - membrane - Scar - tissues - substrate A:
(A).
substrate
Ques:Answer the following question given this paragraph: The strong force predominates and can cause nuclei of complex atoms with many protons to be stable. The electric force of repulsion is responsible for fission, the breaking apart of nuclei, and therefore also for atom bombs and nuclear power. A form of fission where a helium nucleus is a product, is called alpha radiation. The actions of the weak force give rise to beta radiation. A change in nuclear energy can also give rise to gamma radiation , high energy electromagnetic waves. Particles that emit alpha radiation, beta radiation, and gamma radiation go through the process of radioactive decay, which causes the heating of the molten core of the earth, and has even played a role in the mutations in our evolutionary history. Fission and fusion, the latter occurring when light nuclei combine to form new elements, are accompanied by copious amounts of gamma radiation. These processes often produce radioactive nuclei; in nature these radioactive nuclei were forged in the explosive deaths of ancient stars. Q: What electrical force is responsible for fission? Choices: - momentum - velocity - friction - repulsion A:

Ans:repulsion
Ques: Answer the following question given this paragraph: In type 2 diabetes, the body cells cannot use insulin properly. Q: The body cells cannot use insulin properly in which type of diabetes? Choices: - type 1 diabetes - type 3 diabates - type 4 diabetes - type 2 diabetes A:
Ans:
type 2 diabetes
