The mutual gravitational attraction of galaxies naturally tends to hold them on paths that remain close to each other. Typically a cluster contains tens or hundreds of galaxies. There are, however, large clusters with thousands of galaxies, and there are some solitary galaxies.

There are also longer-term responses, which may be on the scale of hours or even days, such as cell division and programmed cell death.

Some answered ‘Writi 10.3 The decibel as a measure of sound amplitude As I mentioned earlier, because a decibel is a way of expressing a ratio, it cannot by itself express the absolute size of anything. To express absolute values it must be referred to a fixed reference quantity, against which whatever is being measured can be compared. In the context of acoustics the reference used is the lower limit of audibility – the threshold of audibility. This varies from person to person, but has a nominal value that can be expressed as a pressure wave with an Tasting menu: Audio highlights from the February 20th 2016 edition Keep on learning   There are more than 800 courses on OpenLearn for you to choose from on a range of subjects. Find out mor 5 Students: David Boudia
