Answer the following question given this paragraph: Quantities have two parts: the number and the unit. The number tells "how many. " It is important to be able to express numbers properly so that the quantities can be communicated properly. Standard notation is the straightforward expression of a number. Numbers such as 17, 101.5, and 0.00446 are expressed in standard notation. For relatively small numbers, standard notation is fine. However, for very large numbers, such as 306,000,000, or for very small numbers, such as 0.000000419, standard notation can be cumbersome because of the number of zeros needed to place nonzero numbers in the proper position. Q: Quantities have two parts: the number (how many) and what else? Choices: - the motion - the member - the credit - he unit A:
he unit

Answer the following question given this paragraph: Figure 7.24 Intervertebral Disc The bodies of adjacent vertebrae are separated and united by an intervertebral disc, which provides padding and allows for movements between adjacent vertebrae. The disc consists of a fibrous outer layer called the anulus fibrosus and a gel-like center called the nucleus pulposus. The intervertebral foramen is the opening formed between adjacent vertebrae for the exit of a spinal nerve. Q: What is the opening formed between adjacent vertebrae for the exit of a spinal nerve called? Choices: - inferior vertebral notch - sympathetic ganglion - spinous process - intervertebral foramen A:
(Answer)
intervertebral foramen
Ques: Answer the following question given this paragraph: An electron is a particle outside the nucleus of an atom that has a negative electric charge. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. As a result, the negative and positive charges "cancel out. " This makes atoms electrically neutral. For example, a carbon atom has six electrons that "cancel out" its six protons. Q: What is the term for a particle outside the nucleus of an atom that has a negative electric charge? Choices: - proton - ion - neutron - electron A:
Ans: electron

Answer the following question given this paragraph: The Scientific Revolution occurred in Europe. This was the beginning of modern Western science. Many scientific advances were made during this time. Copernicus proposed that the sun, not Earth, is the center of the solar system. Q: During the scientific revolution, who proposed that the sun, not earth, is the center of the solar system? Choices: - Newton - Galileo - janus - copernicus A:
(A).
copernicus
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
Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. It begins when the nucleus of a radioactive atom gains a neutron. Q: What term describes the splitting of the nucleus of an atom into two smaller nuclei? Choices: - nuclean fusion - atomic reaction - critical fission - nuclear fission A:
nuclear fission
