B. Can be hurried up once you have it memorized.

Explanation:

A good stretching routine should not be hurried because it has been memorized. This is a bad stretching habit and should not be encouraged in daily routines.

  • Stretching helps to flex the muscle gently after a period of inactivity or over activity.
  • It ensures that our muscles are well straightened out and perfectly in shape.
  • A full body stretch should last a minimum of about five minutes.
  • Stretching helps to improve tissue elasticity and their flexibility

Which of these would be a good model to demonstrate the fact that the galaxies are moving apart as the universe is expanding?
Sergio [31]

Answer: Option A: The spots on the balloon move away as the balloon is inflated.

one of the scientific models describes the galaxies are moving apart as the universe is expanding. This expansion theory came from the observation of red-shifted spectrum from all the directions indicating that the galaxies are moving away.  This can be understood from the inflated balloon. Initially spots can be marked using a colored pen on the balloon.On inflating the balloon, it would be noticed that the spots on the balloon move away. Actually the position of the spots won't change, but the distance between the spots would expand. This is a good model to explain the expanding universe. The galaxies are neither moving in any random direction nor moving forward. So, rest of the options are not good models to explain the theory.
