Q: What term describes the splitting of the nucleus of an atom into two smaller nuclei? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - nuclean fusion - atomic reaction - critical fission - nuclear fission A:
nuclear fission

Q: The two smallest carboxylic acids are formic acid and what else? Read this paragraph and choose the correct option from the provided answers: The two smallest carboxylic acids are formic acid (found in the stingers of ants) and acetic acid (found in vinegar). Many organic compounds are considerably more complex than the examples described here. Many compounds, such as cholesterol discussed in the chapter-opening essay, contain more than one functional group. The formal names can also be quite complex. In http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gobch12through http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch15, we will examine the characteristics and chemistry of other important organic compounds and functional groups. Choices: - carbonates acid - ethylene acid - ascorbic acid - acetic acid A:
acetic acid

Q: Q: What is the force of attraction between fundamental particles called quarks, called. Read this paragraph and choose the correct option from the provided answers: The strong nuclear force is a force of attraction between fundamental particles called quarks, which have a type of charge called color charge. The strong nuclear force is transferred between quarks by fundamental force-carrying particles called gluons. Both protons and neutrons consist of quarks. The exchange of gluons holds quarks together within a proton or neutron. Excess, or residual, strong force holds together protons and neutrons in the nucleus. The strong nuclear force is strong enough to overcome the electromagnetic force of repulsion pushing protons apart. Both forces are represented in the Figure below . Choices: - magnetism - gravity - weak nuclear force - strong nuclear force A:
A: strong nuclear force

Question: Q: The epidermis is made of which closely packed cells? Read this paragraph and choose the correct option from the provided answers: Figure 5.2 Layers of Skin The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. Beneath the dermis lies the hypodermis, which is composed mainly of loose connective and fatty tissues. Choices: - cancer cells - nerve cells - muscle cells - epithelial cells A:
Answer: epithelial cells

Q: What are the specialized building blocks of your body? Read this paragraph and choose the correct option from the provided answers: Introduction Close your eyes and picture a brick wall. What is the basic building block of that wall? A single brick, of course. Like a brick wall, your body is composed of basic building blocks, and the building blocks of your body are cells. Your body has many kinds of cells, each specialized for a specific purpose. Just as a home is made from a variety of building materials, the human body is constructed from many cell types. For example, epithelial cells protect the surface of the body and cover the organs and body cavities within. Bone cells help to support and protect the body. Cells of the immune system fight invading bacteria. Additionally, blood and blood cells carry nutrients and oxygen throughout the body while removing carbon dioxide. Each of these cell types plays a vital role during the growth, development, and day-to-day maintenance of the body. In spite of their enormous variety, however, cells from all organismseven ones as diverse as bacteria, onion, and humanshare certain fundamental characteristics. Choices: - tissues - proteins - muscles - cells A:
(A).
cells
