Answer the following question given this paragraph: The continental slope is the slope that forms the edge of the continent. It is seaward of the continental shelf. In some places, a large pile of sediments brought from rivers creates the continental rise. The continental rise ends at the ocean floor. Much of the ocean floor is called the abyssal plain. Q: What do you call the slope that forms the edge of the continent? Choices: - the land slope - the prevalent slope - the cataclysmic slope - the continental slope A:
the continental slope

Answer the following question given this paragraph: Generators may be set up to produce either direct or alternating current. Generators in cars and most power plants produce alternating current. Regardless of the type of current, all generators change kinetic energy to electrical energy. Q: When using a generator, we are transforming what energy into what energy? Choices: - magnetic into kinetic - thermal into radioactive - mechanical into thermal - kinetic into electrical A:
(Answer)
kinetic into electrical
Ques: Answer the following question given this paragraph: Electrons fill orbitals in a consistent order: they first fill the orbitals closest to the nucleus, then they continue to fill orbitals of increasing energy further from the nucleus. If there are multiple orbitals of equal energy, they will be filled with one electron in each energy level before a second electron is added. The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms to form molecules. Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost shell. The innermost shell has a maximum of two electrons but the next two electron shells can each have a maximum of eight electrons. This is known as the octet rule, which states, with the exception of the innermost shell, that atoms are more stable energetically when they have eight electrons in their valence shell, the outermost electron shell. Examples of some neutral atoms and their electron configurations are shown in Figure 2.7. Notice that in this Figure 2.7, helium has a complete outer electron shell, with two electrons filling its first and only shell. Similarly, neon has a complete outer 2n shell containing eight electrons. In contrast, chlorine and sodium have seven and one in their outer shells, respectively, but theoretically they would be more energetically stable if they followed the octet rule and had eight. Q: Which orbitals do electrons fill first? Choices: - empty orbitals - charged orbitals - furthest from nucleus - closest to the nucleus A:
Ans: closest to the nucleus

Answer the following question given this paragraph: Accuracy and Precision of a Measurement Science is based on observation and experimentthat is, on measurements. Accuracy is how close a measurement is to the correct value for that measurement. For example, let us say that you are measuring the length of standard computer paper. The packaging in which you purchased the paper states that it is 11.0 inches long. You measure the length of the paper three times and obtain the following measurements: 11.1 in. , 11.2 in. , and 10.9 in. These measurements are quite accurate because they are very close to the correct value of 11.0 inches. In contrast, if you had obtained a measurement of 12 inches, your measurement would not be very accurate. The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions). Consider the example of the paper measurements. The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the. Q: How close a measurement is to the correct value for that measurement is known as what? Choices: - frequency - rate - temperature - accuracy A:
(A).
accuracy
Ques:Answer the following question given this paragraph: The amniotic sac is a membrane that surrounds the fetus. It is filled with water and dissolved substances, known as amniotic fluid. Imagine placing a small plastic toy inside a balloon and then filling the balloon with water. The toy would be cushioned and protected by the water. It would also be able to move freely inside the balloon. The amniotic sac and its fluid are like a water-filled balloon. They cushion and protect the fetus. They also let the fetus move freely inside the uterus. Q: What is the membrane that surrounds a fetus called? Choices: - cell membrane - umbilicus - umbilical sac - amniotic sac A:

Ans:amniotic sac
Ques: Answer the following question given this paragraph: The muscular system consists of all the muscles of the body. Muscles are organs composed mainly of muscle cells, which are also called muscle fibers . Each muscle fiber is a very long, thin cell that can do something no other cell can do. It can contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out. There are three types of muscle tissues in the human body: cardiac, smooth, and skeletal muscle tissues. They are shown in Figure below and described below. Q: What are muscle cells in the muscles called? Choices: - human fibers - use fibers - job fibers - muscle fibers A:
Ans:
muscle fibers
