Answer the following question given this paragraph: Figure 12.27 The Synapse The synapse is a connection between a neuron and its target cell (which is not necessarily a neuron). The presynaptic element is the synaptic end bulb of the axon where Ca2+ enters the bulb to cause vesicle fusion and neurotransmitter release. The neurotransmitter diffuses across the synaptic cleft to bind to its receptor. The neurotransmitter is cleared from the synapse either by enzymatic degradation, neuronal reuptake, or glial reuptake. Q: What is the term for a connection between a neuron and its target cell? Choices: - dendrite - axon - impulse - synapse A:
synapse

Answer the following question given this paragraph: Urine is a liquid waste formed by the kidneys as they filter the blood. If you are getting plenty of fluids, your urine should be almost clear. But you might have noticed that sometimes your urine is darker than usual. Do you know why this happens? Sometimes your body is low on water and trying to reduce the amount of water lost in urine. Therefore, your urine gets darker than usual. Your body is striving to maintain homeostasis through the process of excretion. Q: What is the term for liquid waste formed by kidneys? Choices: - blood - feces - sperm - urine A:
(Answer)
urine
Ques: Answer the following question given this paragraph: Like transverse waves, longitudinal waves are mechanical waves, which means they transfer energy through a medium. Unlike transverse waves, longitudinal waves cause the particles of medium to move parallel to the direction of the wave. They are most common in springs, where they are caused by the pushing an pulling of the spring. Although the surface waves on water are transverse waves, fluids (liquids, gases, and plasmas) usually transmit longitudinal waves. Q: Two important types of waves include longitudinal waves and what other kind? Choices: - phenomena - slow - irregular - transverse A:
Ans: transverse
(Q).
Answer the following question given this paragraph: Shield volcanoes often form along divergent plate boundaries. They also form at hotspots, like Hawaii. Shield volcano eruptions are non-explosive. Q: What kind of volcanoes often form along divergent plate boundaries? Choices: - composite - dome - crest - shield A:
(A).
shield
Ques:Answer the following question given this paragraph: Temperature decreases in the mesosphere with altitude. This is because the heat source is the stratosphere. Q: What part of the atmosphere is the heat source? Choices: - troposphere - magnetosphere - ionosphere - stratosphere A:

Ans:stratosphere
Answer the following question given this paragraph: A: The weakest acid on the scale is milk, which has a pH value between 6.5 and 6.8. The strongest base on the scale is liquid drain cleaner, which has a pH of 14. Q: Is an acid lower or higher than 7 on the ph scale? Choices: - exactly 7 - higher than 7 - twice as much as 7 - lower than 7 A:
lower than 7
