D)four cells that each have half as many chromosomes as the parent cell
A. The molecules start packed together very tightly in a solid. Then when it turns to water, the molecules can move around each other freely, but still contained. When water turns to vapor, the molecules are going crazy moving around. They are not contained at all and bounce of of each other freely.
b. The temperature rises. (ice turns to water at 33 degrees and water turns to vapor at 212 degrees)
Explanation:
Given that,
Length of the spring, l = 50 cm
Mass, m = 330 g = 0.33 kg
(A) The mass is released and falls, stretching the spring by 28 cm before coming to rest at its lowest point. On applying second law of Newton at 14 cm below the lowest point we get :

(B) The amplitude of the oscillation is half of the total distance covered. So, amplitude is 14 cm.
(C) The frequency of the oscillation is given by :

All of the following methods are ways to correct a run-on sentence except: Putting a comma in between the complete sentences.
One of the uses of semi-colon is to separate two complete or independent sentences. A conjunction can also be used such as: and, however and but, to connect two complete sentences and transform them into a compound sentence.
