Answer:
Density of half of the block will remain unchanged.
Explanation:
Here, a brick has been given and is stated that brick has been chopped in half. so, what will be the new density of that half block..
Density is been defined as mass per unit volume.
so, even when the brick is cut in half the density remains unchanged.
Density is said to be an intensive material which does not depend upon size, phase, amount of the given material in the given system.
Density has a direct relationship with two properties i.e.
mass and volume.
when one property gets changed other one follows.
so, finally the density doesn't gets changed.

You can use a pH level scale like the one I attached, to determine each solution.
Both too much and too little intake of zinc can impair the immune function. In addition to this, high intake of zinc can lessen the absorption of both iron and copper which are two of the most essential minerals needed by the human body.
Based on this:

Answer and Explanation:
A) Unconditioned Stimulus- The onion
B) Unconditional Response- Crying
C) Conditioned Stimulus- Chiming clock
D) Conditioned Response- Crying
In the above scenario( an example of classical conditioning), Elmer has been conditioned by the continuous iterations of having to cook everyday by 5pm. He cooks with onions by 5pm around the same time his uncle's clock chimes five times. He cries/has teary eyes(unconditioned response) because of the response to the onions(unconditioned stimulus) around the same time the clock chimes five times thereby conditioning his response so that even when the onions isn't there/he isn't even cooking, he tears up to the clock chimes around 5pm. The clock is therefore a conditioned stimulus and there is a conditioned response of crying.
The unconditioned response to an unconditioned stimulus happens naturally(an instinct) because it is a biological response to the onions, not conditioned.
