Answer the following question given this paragraph: Earth is not the only active planetary body in the solar system. Io, one of Jupiter's moons, is home to fantastic volcanic eruptions. Volcanism is much hotter than on Earth. Lava curtains and fountains are common. In this color image, the Galileo spacecraft spotted two volcanic plumes. One is spewing high above the planet on the horizon. The second is near he boundary between day and night. Besides being hotter than Earth's volcanism, eruptions on Io have a different composition. They are mostly sulfur!. Q: What planet in our solar system has a moon with volcanic activity? Choices: - Mars - Venus - Saturn - jupiter A:
jupiter

Answer the following question given this paragraph: 31.3 Peripheral nervous system The peripheral nervous system is broken down into two sub-systems, the somatic nervous system and the autonomic nervous system. ANS - Autonomic Nervous System The ANS has two components - parasympathetic and sympathetic. The sympathetic nervous system is the "fight or flight" or fright response and results in an increased heart rate, increased rate of breathing, and an elevated blood glucose level. There is also decreased digestion. The second neurotransmitter is epinephrine. In this case, the first neuron is short and the second neuron is long. The parasympathetic nervous system is the rest and digest system. Drugs must be able to pass the blood brain barrier to have an effect on the CNS. Drugs act by affecting the neuron and how likely it is to fire an action potential. Stroke occurs when there is a blood clot that goes to the brain and prevent blood flow. Q: What are the two components of the autonomic nervous system? Choices: - empathetic and sympathetic - crystallisation and sympathetic - neurons and sympathetic - parasympathetic and sympathetic A:
(Answer)
parasympathetic and sympathetic
Ques: Answer the following question given this paragraph: The Sun and many other light sources produce waves that are randomly polarized (see Figure 27.39). Such light is said to be unpolarized because it is composed of many waves with all possible directions of polarization. Polaroid materials, invented by the founder of Polaroid Corporation, Edwin Land, act as a polarizing slit for light, allowing only polarization in one direction to pass through. Polarizing filters are composed of long molecules aligned in one direction. Thinking of the molecules as many slits, analogous to those for the oscillating ropes, we can understand why only light with a specific polarization can get through. The axis of a polarizing filter is the direction along which the filter passes the electric field of an EM wave (see Figure 27.40). Q: The sun and many other light sources produce waves that are randomly this? Choices: - obfuscated - amplified - colored - polarized A:
Ans: polarized

Answer the following question given this paragraph: Cells in blood include red blood cells, white blood cells, and platelets. Q: Cells in blood include red blood cells, white blood cells, and what? Choices: - protons - droplets - plasmids - platelets A:
(A).
platelets
Ques:Answer the following question given this paragraph: Another example is carbon dioxide. This gas is produced from a variety of reactions, often by the burning of materials. The structure of the gas consists of one atom of carbon and two atoms of oxygen. Carbon dioxide production is of interest in many areas, from the amount we breather out to the amount of the gas produced by burning wood or fossil fuels. By knowing the exact composition of carbon dioxide, we can make predictions as to the effects of different chemical processes. Q: The structure of the gas carbon dioxide consists of one atom of carbon and two atoms of what? Choices: - sulfur - methane - Helium - oxygen A:

Ans:oxygen
Question: Answer the following question given this paragraph: Beautiful sunsets are another manifestation of Rayleigh scattering that occurs when light travels long distances through the atmosphere. The blue light and some green is scattered away, making the sun appear red. Q: What makes sunsets appear red? Choices: - wavelength scattering - reflection scattering - floral scattering - rayleigh scattering A:
Answer:
rayleigh scattering
