Most galaxies are moving away from us because they known as to be blue shifted as stated above!!

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.

Explain in detail how to decide the number of replications in a simulation study. Use fixed-sample-size and sequential procedure
erik [133]

Explanation:

Fixed sample size:

In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.

Sequential procedures:

→Sequential procedures helps while we are collecting the data.

→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.

→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.

→In this two or more blocks of different sizes are prepared for testing.

→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

JulijaS [17]

Answer:

Potato

Explanation:

Hypertension is a condition developed due to the continuous high or elevated blood pressure in the arteries in the body. The main cause of hypertension is the contraction of the arteries and the consumption of food with a high level of sodium and low level of potassium.

It is suggested that people with hypertension should consume a diet rich in potassium but with a low amount of sodium.  The good source of food with a high level of potassium is baked potato which provides carbohydrates also, salmon, and the banana.

Since the amount of potassium is high in the baked potato, therefore, is the correct answer.
