Answer:
Air is a matter
Explanation:
Matter is anything that has mass and takes up space. So, in order to prove that air is matter, we need to prove that air has mass and takes up space. It's easier to prove that air takes up space, so let's do that part of the problem first.
Get a balloon and inflate the balloon with air. The balloon get larger as you put air into them. The only way that air could make them get larger is if air takes up space.
Also the balloon can be weight before air is added and after addition of the air. The weight will be much after adding air
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. Draw and label the structure of a typical nerve cell.
The lens is the clear oval structure in the eye that focuses light as an image on the retina.
Answer:<em>Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer. Confined aquifers are those in which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.</em>

<span>D. Composting
Let's take a look at the various options and see if they make sense, given the context of the problem.
A. Biological action
* This option is rather vague and non-specific. It's a possible choice, but if there's something better, then choose it rather than this. Probable wrong choice.
B. Carbon sequestration
* This is the process of storing carbon long term to reduce the amount of CO2 in the atmosphere. Unless Ben has one heck of a lot of organic waste to get rid of, this is a rather silly option and therefore, wrong.
C. Incineration
* The key thing about the problem is "eco-friendly". Incineration will get rid of Ben's leftover food and organic waste, but in doing so will release carbon dioxide into the air and is likely to require some fuel in addition to the organic waste he wants to get rid of. So this too is a bad choice.
D. Composting
* This is the process of breaking down organic matter into compost that can be used as a soil enrichment treatment or fertilizer. The key thing to remember is that the material to be composted has to be organic. Doing this will allow Ben to have compost that he can use in the future on his garden. Overall, this is both an inexpensive and eco-friendly method for Ben to dispose of his leftover food and organic waste.</span>
