Answer the following question given this paragraph: An innate behavior is any behavior that occurs naturally in all animals of a given species. An innate behavior is also called an instinct . The first time an animal performs an innate behavior, the animal does it well. The animal does not have to practice the behavior in order to get it right or become better at it. Innate behaviors are also predictable. All members of a species perform an innate behavior in the same way. From the examples described above, you can probably tell that innate behaviors usually involve important actions, like eating and caring for the young. Q: What type of behavior occurs naturally in all animals of a given species? Choices: - learned - observational - reflex - innate A:
innate

Answer the following question given this paragraph: There are some properties that all liquids have. The liquid that we are most familiar with is probably water, and it has these properties. Other liquids have them as well, which is something to keep in mind. All liquids have a certain portion of their particles having enough energy to enter the gas phase, and if these particles are at the surface of the liquid, they do so ( - ball-ch10_s03_f01). The formation of a gas from a liquid at temperatures below the boiling point is called evaporation. At these temperatures, the material in the gas phase is called vapor, rather than gas; the term gas is reserved for when the gas phase is the stable phase. Figure 10.5 Evaporation. Q: What do we call the formation of a gas from a liquid at temperatures below the boiling point? Choices: - melting - pulverization - steaming - evaporation A:
evaporation

Answer the following question given this paragraph: 29.6 Mammals Mammals in general are vertebrates that possess hair and mammary glands. The mammalian integument includes various secretory glands, including sebaceous glands, eccrine glands, apocrine glands, and mammary glands. Mammals are synapsids, meaning that they have a single opening in the skull. A key characteristic of synapsids is endothermy rather than the ectothermy seen in other vertebrates. Mammals probably evolved from therapsids in the late Triassic period, as the earliest known mammal fossils are from the early Jurassic period. There are three groups of mammals living today: monotremes, marsupials, and eutherians. Monotremes are unique among mammals as they lay eggs, rather than giving birth to young. Eutherian mammals are sometimes called placental mammals, because all species possess a complex placenta that connects a fetus to the mother, allowing for gas, fluid, and nutrient exchange. Q: What makes monotremes different than other mammals? Choices: - they lack backbones - they spawn - they reproduce asexually - they lay eggs A:
they lay eggs

Answer the following question given this paragraph: Individual nucleotides can be linked together through their phosphate groups to form nucleic acid polymers. Once constructed, DNA generally exists as two strands that are linked together by hydrogen bonds, producing a double-helical structure (see Figure below ). Q: Individual nucleotides can be linked together through their phosphate groups to form? Choices: - atoms - nitrous acid polymers - dna - nucleic acid polymers A:
nucleic acid polymers
