Ques:Q: What is the term for behaviors that are closely controlled by genes with little or no environmental influence? Read this paragraph and choose the correct option from the provided answers: Behaviors that are closely controlled by genes with little or no environmental influence are called innate behaviors . These are behaviors that occur naturally in all members of a species whenever they are exposed to a certain stimulus. Innate behaviors do not have to be learned or practiced. They are also called instinctive behaviors. An instinct is the ability of an animal to perform a behavior the first time it is exposed to the proper stimulus. For example, a dog will drool the first timeand every timeit is exposed to food. Choices: - observational behaviors - reflex behaviors - learned behavior - innate behaviors A:

Ans:innate behaviors

Ques:Q: Any large molecule is referred to as what? Read this paragraph and choose the correct option from the provided answers: Carbon's affinity for covalent bonding means that many distinct and relatively stable organic molecules nevertheless readily form larger, more complex molecules. Any large molecule is referred to as macromolecule (macro- = "large"), and the organic compounds in this section all fit this description. However, some macromolecules are made up of several "copies" of single units called monomer (mono- = "one"; -mer = "part"). Like beads in a long necklace, these monomers link by covalent bonds to form long polymers (poly- = "many"). There are many examples of monomers and polymers among the organic compounds. Monomers form polymers by engaging in dehydration synthesis (see Figure 2.14). As was noted earlier, this reaction results in the release of a molecule of water. Each monomer contributes: One gives up a hydrogen atom and the other gives up a hydroxyl group. Polymers are split into monomers by hydrolysis (-lysis = "rupture"). The bonds between their monomers are broken, via the donation of a molecule of water, which contributes a hydrogen atom to one monomer and a hydroxyl group to the other. Choices: - cellular - microtubule - polymer - macromolecule A:

Ans:macromolecule

Ques:Q: What is the name for speed with a direction? Read this paragraph and choose the correct option from the provided answers: Speed represents how quickly an object is moving through space. Velocity is speed with a direction, making it a vector quantity. If an object's velocity changes with time, the object is said to be accelerating. As we'll see in the next chapters, understanding the acceleration of an object is the key to understanding its motion. We will assume constant acceleration throughout this chapter. Choices: - distance - acceleration - trajectory - velocity A:

Ans:velocity
