Due to the surface of the water, light insects are able to walk on the surface of water.
Surface tension also accounts for those with wide feet (generally webbed feet). They have more area on the underside of their feet and if they move fast enough (depending on their weight - the heavier they weigh, the faster they must go to keep on the surface of the water), they are able to "walk on water".
Answer: 1. 0.6 m/sec. 2. 6m/sec
Explanation:
Frequency = 0.1/sec wavelength = 6 m
speed = freq x wavelength = 0.6 m/sec
speed = distance/time = 60/10 = 6m/sec
At the smallest level of organization, the DNA wraps itself around small globular proteins called histones. Complexes of histones and DNA form nucleosomes, which appear as "beads" on the DNA strand. Chromatin refers to the decondensed DNA that has not formed separate chromosomes.
