Most of the galaxies in the Universe are moving away from us and as a result, the light that they emit is shifted to the red end of the spectrum due to an increase in wavelength as the Universe expands. When a galaxy moves towards us, for example in the case of the Andromeda Galaxy (M31), the wavelength of the light emitted is shortened thanks to the Doppler Effect (the same effect that causes the siren of an ambulance to rise and fall in pitch as it drives by), shifting the light to the blue end of the spectrum. The galaxy is then said to be blue-shifted.

3. Describe at least three types of medical interventions that can be used to treat and repair broken bones. Explain the theory
hjlf

Answer:

1. Casting

2. Open reduction and internal fixation

3. Open reduction and external fixation

Explanation:

Casting is the process of making use of plaster-of- Paris to cure a fracture.

Open reduction, and internal fixation can be described as a situation whereby surgery is used to repair the fracture-frequently, and involves the use of metal rods, screws or plates to repair the bone. These things remain in place, under the skin, after the surgery. This procedure is adopted when the complicated fractures are not able to be realigned (reduced) by casting.

Open reduction, and external fixation is known to involve surgery to repair the fracture, and placement of a external fixation device on the limb with the fracture. This device is an external frame which supports the bone and hold it in the correct position while it is healing.
