Answer: A) Rainfall Explanation: Savannas are home to a wide diversity of animals. Many animals of the savanna migrate throughout the year, searching for food and water. Many of the droughts are seasonal and hit one area before another, so animals are constantly following the rains.   Hence, Rain fall is what often governs animal migration on savannas.

Social Darwinism was a prominent intellectual theory that was used to justify European Imperialism in the 19th and early 20th centuries. Social Darwinism held that those made better or worse by industrialization were based on the natural predisposition of the people effected. For those who were made better off, the success of those people demonstrated that they had a well-evolved culture and this expansion would help remove or improve underperforming cultures, which were those "chosen" by the fact that they were performing poorly.   Imperialism may encompass a broad range of meanings, including the foreign occupation of one nation by another; one society's control of the internal politics of another; and, especially, foreign extraction of a less powerful nation's natural resources and/or exploitation of its indigenous human resources.   All in all, according to the Social Darwinist, Imperialism was the natural expansion and success of a well-evolved culture and this expansion would help remove or improve underperforming cultures.

Answer: C) Peso Explanation:

In most cases, you will have no idea who you are competing with for a particular job. So this type of question really gives you a chance to open-up your strengths as a candidate with an emphasis on any assets that might separate you from the typical applicant. Think about what you bring to the table that you truly believe is unique - the easiest way to do is to think of your own personal stories that demonstrate your work ethic, skills, and dedication. Most people have some or all of those skills, but the unique stories are what make people stand out in interviews.

Answer: A) its supply or demand is not sensitive to price changes. Explanation: A good that is inelastic does not have very stretchy demand. In economic terms, the quantity demanded does not change a lot when the price changes. What do I mean by "does not change a lot"? If the percent change in quantity demanded is less than the percent change in price, economists label the demand for the good as inelastic.   So, if the price of a good increases by 10 percent and the quantity demanded decreases by only 5 percent, that good is said to have inelastic demand. The quantity demanded does not stretch much relative to the change in price.   Hence, in this case, consumers are not considered very sensitive, or responsive, to a change in the price of that good.

Answer: D) Covalent- network Explanation: Graphite is a covalent-network type of crystalline solid.   There are two main categories of solids. 1. Crystalline solids and 2. Amorphous solids. Crystalline solids are those in which the atoms, ions, or molecules that make up the solid exist in a regular, well-defined arrangement. There are four types of crystalline solids : Ionic solids :— Made up of positive and negative ions and held together by electrostatic attractions. They’re characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl. Molecular solids :— Made up of atoms or molecules held together by London dispersion forces, dipole-dipole forces, or hydrogen bonds. Characterized by low melting points and flexibility and are poor conductors. An example of a molecular solid is sucrose. Covalent-network (also called atomic) solids :— Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors. Examples of this type of solid are diamond and graphite, and the fullerenes. As you can see below, graphite has only 2-D hexagonal structure and therefore is not hard like diamond. The sheets of graphite are held together by only weak London forces! Metallic solids :— Made up of metal atoms that are held together by metallic bonds. Characterized by high melting points, can range from soft and malleable to very hard, and are good conductors of electricity.

Answer: C) The cell uses information from messenger RNA to produce proteins Explanation: Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.   In short, during the process of translation source language text is conveyed to destination language.
