Answer the following question given this paragraph: Many birds learn to avoid eating monarch butterflies, like the one pictured in Figure below . Monarch butterflies taste bad and make birds sick. In this case, the behavior is learned because it is punished with a nasty taste and illness. Q: What type of butterfly do birds avoid eating since it makes them sick? Choices: - sphingidae - noctuidae - pyralidae - monarch butterflies A:
monarch butterflies

Answer the following question given this paragraph: The stomach also releases a very strong acid, called hydrochloric acid. This acid kills most pathogens that enter the stomach in food or water. Urine is also acidic, so few pathogens can grow in it. Q: What is the acid that is released by the stomach that kills most pathogens that enter the stomach? Choices: - Nitric Acid - Hydrofluoric Acid - Sulfuric Acid - hydrochloric acid A:
(Answer)
hydrochloric acid
Ques: Answer the following question given this paragraph: The frequency factor is used to convert concentrations to collisions per second. Equation 14.39 is known as the Arrhenius equation and summarizes the collision model of chemical kinetics, where T is the absolute temperature (in K) and R is the ideal gas constant [8.314 J/(Kmol)]. Ea indicates the sensitivity of the reaction to changes in temperature. The reaction rate with a large Ea increases rapidly with increasing temperature, whereas the reaction rate with a smaller Ea increases much more slowly with increasing temperature. If we know the reaction rate at various temperatures, we can use the Arrhenius equation to calculate the activation energy. Taking the natural logarithm of both sides ofEquation 14.39, Equation 14.40. Q: What is used to convert concentrations to collisions per second? Choices: - speeds factor - collision meter - particles factor - frequency factor A:
Ans: frequency factor

Answer the following question given this paragraph: Tarsal Bones The posterior half of the foot is formed by seven tarsal bones (Figure 8.19). The most superior bone is the talus. This has a relatively square-shaped, upper surface that articulates with the tibia and fibula to form the ankle joint. Three areas of articulation form the ankle joint: The superomedial surface of the talus bone articulates with the medial malleolus of the tibia, the top of the talus articulates with the distal end of the tibia, and the lateral side of the talus articulates with the lateral malleolus of the fibula. Inferiorly, the talus articulates with the calcaneus (heel bone), the largest bone of the foot, which forms the heel. Body weight is transferred from the tibia to the talus to the calcaneus, which rests on the ground. The medial calcaneus has a prominent bony extension called the sustentaculum tali ("support for the talus") that supports the medial side of the talus bone. Q: The posterior half of the foot is formed by seven tarsal bones. the most superior of these bones is called? Choices: - metatarsal - patella - calcareous - talus A:
(A).
talus
Ques:Answer the following question given this paragraph: Prokaryotic organisms reproduce asexually by binary fission , a process that produces identical offspring ( Figure below ). In asexual reproduction , a single parent produces genetically identical offspring. As prokaryotes do not have a nucleus, and have only one circular chromosome, they do not need to reproduce by the same mechanism as eukaryotic cells; mitosis does not exist in prokaryotic cells . Prokaryotic cell division is a much simpler process. In prokaryotic cell division, after the single chromosome is copied, the cell grows larger. Eventually the two chromosomes separate and move to opposite ends of the cell. Newly formed cell membrane then grows into the center of the cell, separating the two chromosomes, and forming two genetically identical daughter cells. Some eukaryotic organelles, such as mitochondria and chloroplasts, also divide by binary fission. Q: How do prokaryotic organisms reproduce asexually? Choices: - mitosis - residual fission - kinetic fission - binary fission A:

Ans:binary fission
