Answer the following question given this paragraph: Fine-grained mud in the deep ocean comes from silts and clays brought from the land by wind. The particles are deposited on the sea surface. they slowly settle to the deep ocean floor, forming brown, greenish, or reddish clays. Volcanic ash may also settle on the seafloor. Q: Fine-grained mud in the deep ocean comes from silts and clays brought from the land by? Choices: - fire - water - waves - wind A:
wind

Ques: Answer the following question given this paragraph: Biotechnology has been used to create transgenic crops. Transgenic crops are genetically modified with new genes that code for traits useful to humans. The diagram in Figure below shows how a transgenic crop is created. You can learn more about how scientists create transgenic crops with the interactive animation "Engineer a Crop: Transgenic Manipulation" at this link: http://www. pbs. org/wgbh/harvest/engineer/transgen. html . Q: What is the term for crops that are genetically modified with new genes that code for traits useful to humans? Choices: - mutant - embryonic - carcinogenic - transgenic A:
Ans: transgenic
(Q).
Answer the following question given this paragraph: Nonmetals are elements that do not conduct electricity. They are the second largest class of elements. Nonmetals are also poor conductors of heat. The majority of nonmetals are gases. Solid nonmetals are dull and brittle. Q: Elements that do not need to conduct electricity are known as what? Choices: - alloys - carbonates - silicates - nonmetals A:
(A).
nonmetals
Ques:Answer the following question given this paragraph: 25.1 The Ray Aspect of Light There are three ways in which light can travel from a source to another location. (See Figure 25.3. ) It can come directly from the source through empty space, such as from the Sun to Earth. Or light can travel through various media, such as air and glass, to the person. Light can also arrive after being reflected, such as by a mirror. In all of these cases, light is modeled as traveling in straight lines called rays. Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray. The word ray comes from mathematics and here means a straight line that originates at some point. It is acceptable to visualize light rays as laser rays (or even science fiction depictions of ray guns). Ray The word "ray" comes from mathematics and here means a straight line that originates at some point. Q: Regardless of the mode, light is modeled as traveling in straight lines called what? Choices: - waves - arrows - electrons - rays A:

Ans:rays
Ques: Answer the following question given this paragraph: DNA. By contrast though, bacterial DNA is contained in a large, circular strand. This single chromosome is located in a region of the cell called the nucleoid . The nucleoid is not an organelle, but a region within the cytoplasm. Many bacteria also have additional small rings of DNA known as plasmids . Q: Bacterial dna is contained in a large, circular strand; this single chromosome is located in a region of the cell called what? Choices: - polypeptide - amino acid - nucleic acid - the nucleoid A:
Ans:
the nucleoid
