Q: Answer the following question given this paragraph: The organs of Corti contain hair cells, which are named for the hair-like stereocilia extending from the cell's apical surfaces (Figure 14.8). The stereocilia are an array of microvilli-like structures arranged from tallest to shortest. Protein fibers tether adjacent hairs together within each array, such that the array will bend in response to movements of the basilar membrane. The stereocilia extend up from the hair cells to the overlying tectorial membrane, which is attached medially to the organ of Corti. When the pressure waves from the scala move the basilar membrane, the tectorial membrane slides across the stereocilia. This bends the stereocilia either toward or away from the tallest member of each array. When the stereocilia bend toward the tallest member of their array, tension in the protein tethers opens ion channels in the hair cell membrane. This will depolarize the hair cell membrane, triggering nerve impulses that travel down the afferent nerve fibers attached to the hair cells. When the stereocilia bend toward the shortest member of their array, the tension on the tethers slackens and the ion channels close. When no sound is present, and the stereocilia are standing straight, a small amount of tension still exists on the tethers, keeping the membrane potential of the hair cell slightly depolarized. Q: When the pressure waves from the scala move the basilar membrane, the tectorial membrane slides across the what? Choices: - dendrites - keratin - cytoplasm - stereocilia A:
A: stereocilia
Question: Answer the following question given this paragraph: After implantation occurs, the blastocyst is called an embryo . The embryonic stage lasts through the eighth week following fertilization. During this time, the embryo grows in size and becomes more complex. It develops specialized cells and tissues and starts to form most organs. For an interactive animation of embryonic development, go to this link: http://health. howstuffworks. com/adam-200129. htm . Q: What is the blastocyst called after implantation? Choices: - trophoblast - an nucleus - an produce - an embryo A:
Answer: an embryo

Answer the following question given this paragraph: In biology, energy is required for ecosystems to survive, as all living organisms need energy. Within an organism, energy is needed for growth and development of a biological cell or an organelle within that cell. Energy is also needed for all biochemical reactions within that cell. Therefore, energy is stored within cells in the chemical bonds of substances such as carbohydrates (including sugars), lipids, and proteins. This energy is released during aerobic respiration. Q: In biology, what is required for ecosystems to survive? Choices: - helium - space - minerals - energy A:
**Answer**
energy
