Q: When an ionic compound dissociates in water, water molecules surround each ion and separate it from the rest of the what? Read this paragraph and choose the correct option from the provided answers: When an ionic compound dissociates in water, water molecules surround each ion and separate it from the rest of the solid.

Q: What giant planet is far away from and much less dense than earth? Read this paragraph and choose the correct option from the provided answers: Jupiter is truly a giant! The planet has 318 times the mass of Earth, and over 1,300 times Earth's volume. So Jupiter is much less dense than Earth. Because Jupiter is so large, it reflects a lot of sunlight. When it is visible, it is the brightest object in the night sky besides the Moon and Venus. Jupiter is quite far from the Earth. The planet is more than five times as far from Earth as the Sun. It takes Jupiter about 12 Earth years to orbit once around the Sun. Choices: - venus - uranus - mars - jupiter A:

Q: The brain is said to contain gray matter, while what related structure contains white matter separated into columns? Read this paragraph and choose the correct option from the provided answers: White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tractsthe latter carrying motor commands down from the brain to the spinal cord to control output to the periphery. Choices: - brain stem - amygdala - orbital lobe - spinal cord A:
**Answer**
spinal cord
