Answer:
1. Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current.
2. Acids have a sour taste.
3. Acids change the color of certain acid-base indicators.
4. Acids react with active metals to yield hydrogen gas.
Explanation:
I looked it up.
It is the “parent” generation, or the “paternal” one which the rest are observed from.
Answer:
32 mm
Explanation:
The field of view is the total area visible through the microscope
. The diameter of the field of view can be measured.
There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.
The relationship between field diameter and magnification is:
magnification of A * field diameter of A = magnification of B * field diameter of B
120X * 8 mm = 30X * B
B = 120X / 30X * 8 mm
B = 32 mm = 32000 μm
The field diameter of 30X magnification is 32 mm (32000 μm)
Because evolution has not been explicitly proven. There has been some evidence, but there is not enough real proof to support this. Even the man who invented the theory of evolution ended up not believing in his own theory at the time of his death. Overall, the premise of evolution is built on an unstable rock, a theory.
