Answer the following question given this paragraph: Kinetic energy is the energy of moving matter. Anything that is moving has kinetic energyfrom atoms in matter to stars in outer space. Things with kinetic energy can do work. For example, the spinning saw blade in the photo above is doing the work of cutting through a piece of metal. Q: What type of energy is the energy of moving matter? Choices: - dynamic energy - residual energy - potential energy - kinetic energy A:
kinetic energy
Q: Answer the following question given this paragraph: Materials that have low resistance to electric current are called electric conductors. Many metals are good electric conductors. Q: What are materials that have a low resistance to electrical current called? Choices: - electrons - resistors - fast conductors - electrical conductors A:
A: electrical conductors
Question: Answer the following question given this paragraph: Some mammals are omnivores. Omnivores are heterotrophs that eat a mix of plant and animal foods. Mammals that are omnivores include bears, foxes, rats, pigs, and human beings. The chimpanzees in Figure below are also omnivorous mammals. In the wild, they eat mainly plant foods, but they supplement plants with birds, bird eggs, insects, small monkeys, and other small mammals. Their favorite and most common food, however, is fruit. Animals that eat mainly fruit are called frugivores. Q: What is the name for a kind of animal that eats a mix of plant and animal foods. Choices: - an smorgasbord - a carnivore - an herbivore - an omnivore A:
Answer: an omnivore

Answer the following question given this paragraph: the conditions, amino acids can act as either acids or bases, which means that proteins act as buffers. The pH at which an amino acid exists as the zwitterion is called theisoelectric point (pI). The amino acids in a protein are linked together by peptide bonds. Protein chains containing 10 or fewer amino acids are usually referred to as peptides, with a prefix such as di- or tri- indicating the number of amino acids. Chains containing more than 50 amino acid units are referred to as proteins orpolypeptides. Proteins are classified globular or fibrous, depending on their structure and resulting solubility in water. Globular proteins are nearly spherical and are soluble in water; fibrous proteins have elongated or fibrous structures and are not soluble in water. Protein molecules can have as many as four levels of structure. The primary structure is the sequence of amino acids in the chain. The secondary structure is the arrangement of adjacent atoms in the peptide chain; the most common arrangements are -helices or -pleated sheets. The tertiary structureis the overall three-dimensional shape of the molecule that results from the way the chain bends and folds in on itself. Proteins that consist of more than one chain have quaternary structure, which is the way the multiple chains are packed together. Four types of intramolecular and intermolecular forces contribute to secondary, tertiary, and quaternary structure: (1) hydrogen bonding between an oxygen or a nitrogen atom and a hydrogen atom bound to an oxygen atom or a nitrogen atom, either on the same chain or on a neighboring chain; (2) ionic bondingbetween one positively charged side chain and one negatively charged side chain; (3) disulfide linkages between cysteine units; and (4) dispersion forcesbetween nonpolar side chains. Because of their complexity, protein molecules are delicate and easy to disrupt. Adenatured protein is one whose conformation has been changed, in a process called denaturation, so that it can no longer do its physiological job. A... Q: Protein chains containing 10 or fewer amino acids are usually referred to as what? Choices: - polypeptides - protons - carboxyl - peptides A:
**Answer**
peptides
Answer the following question given this paragraph: Nonrandom Mating If individuals nonrandomly mate with their peers, the result can be a changing population. There are many reasons nonrandom mating occurs. One reason is simple mate choice; for example, female peahens may prefer peacocks with bigger, brighter tails. Traits that lead to more matings for an individual become selected for by natural selection. One common form of mate choice, called assortative mating, is an individual's preference to mate with partners who are phenotypically similar to themselves. Another cause of nonrandom mating is physical location. This is especially true in large populations spread over large geographic distances where not all individuals will have equal access to one another. Some might be miles apart through woods or over rough terrain, while others might live immediately nearby. Q: One common form of mate choice, called assortative mating, is an individual's preference to mate with partners who are what? Choices: - close to themselves - different from themselves - far away from - similar to themselves A:
similar to themselves
