Answer:

The correct answer is "True".

Explanation:

Some species of jellyfish use a form of jet propulsion to swim and get around the sea. For instance, the jellyfish <em>Polyorchis penicillatus</em> contracts its subumbrellar swimming muscles to gain power, which it uses as mechanical energy to perform a jet cycle while swimming. Some studies in this regard have been performed, measuring even the amount of energy needed in the muscles for the jellyfish to swim.

How does stress (the fight-or-flight response) affect vision?
densk [106]

Answer: I think that stress affects the vision because when your mind is only focused on fighting that something or fleeing from it, that's all you're going to see/be focused on.

For example if your mind was focused on "Fight" then that would be what your doing whether you like it or not.

If your mind is focused on "Flight" then you would be trying to escape from whatever it is almost like your body is moving on it's own.
