It depends on the indicator, and the pH range over which it will experience a colour change. Some indicators will change colour<span> in an acidic solution, others will not. For example, blue litmus paper will turn red in an acidic solution, but red litmus paper will not change colour. The test would be inconclusive with red litmus paper, since it does not change colour in an acid and in a neutral solution.</span>
B.Warmer air molecules move faster and get farther apart. As they get farther apart, they become less dense and rise.
Mass × Velocity = Momentum

Answer:
Femur
Explanation:
The bone to forensically analyze in order to create a height profile of the victims would the <u>femur</u>.
The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.
<em>For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.</em>
The smallest size of the insect that the bats can detect corresponds to the wavelength of the chirp they emit.
Their chirp has a frequency of
and the speed of the chirp is equal to the speed of sound in air:
Therefore the wavelength of the chirp is
which corresponds to a size of 4.76 mm.
