Answer the following question given this paragraph: The addition of electrons always results in an anion that is larger than the parent atom. When the electrons outnumber the protons, the overall attractive force that the protons have for the electrons is decreased. The electron cloud also spreads out because more electrons results in greater electron-electron repulsions. Notice that the group 16 ions are larger than the group 17 ions. The group 16 elements each add two electrons while the group 17 elements add one electron per atom for form the anions. Q: Electrons always result in what? Choices: - A HYPER-PIGMENTATION THAT IS LARGER THAN THE PARENT ATOM - an contraposition that is larger than the parent atom - an dissociative that is larger than the parent atom - an anion that is larger than the parent atom A:
(Answer)
an anion that is larger than the parent atom
Ques: Answer the following question given this paragraph: Archaeological evidence suggests that people have been using tin for at least 5500 years. Tin is used to form many useful alloys (mixtures of two or more metals). Bronze is an alloy of tin and copper, while solder is an alloy of tin and lead. Q: What is an alloy of both tin and copper? Choices: - Cobalt - silver - Aluminium - bronze A:
Ans: bronze

Ques:Answer the following question given this paragraph: A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Each bacterium is a single cell. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called organelles. In humans, as in all organisms, cells perform all functions of life. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. This book covers eleven distinct organ systems in the human body (Figure 1.4 and Figure 1.5). Assigning organs to organ systems can be imprecise since organs that "belong" to one system can also have functions integral to another system. In fact, most organs contribute to more than one system. Q: What is the smallest independently functioning unit of a living organism? Choices: - proteins - molecule - atom - cell A:

Ans:cell
