After any period in a place where the force of gravity is less than on the surface of the earth (or nearly weightless in orbit), muscles will begin to atrophy. The longer in space the weaker you get becuase the muscles do not have to counter the force of gravity. This also includes the heart muscle so the astronauts must be monitored while in space and for a while after their return to earth.
seismometer.
A seismometer is used by astronauts to study extremely weak moon quakes. It is a sensitive instrument that can detect and measure the vibrations caused by these quakes.
Astronauts can swallow while in space because the muscles involved in swallowing, such as the throat muscles and esophagus, can still function normally in microgravity. The lack of gravity does not affect the ability of these muscles to move food and liquids from the mouth to the stomach.
Yes, women can definitely be astronauts. Numerous women have successfully become astronauts and have participated in space missions conducted by various space agencies around the world, including NASA. Gender is not a barrier to becoming an astronaut.
They exercise for up to 2 hours each day, so that their bones and muscles don't become weak.
Their bodies would become very weak.
in zero gravity, your muscles dont have to work very hard unless youre doing something. exercise for astronauts is important so that muscles dont become weak from not being used - also bones become weaker and less dense in zero gravity and nobody knows exactly why yet
If you are ill for a long time, your muscles can become weak and atrophy can occur.
There are quite a few reasons why weak muscles might shake. These muscles could just be spending the last of their energy.
It doesn't. The only way that would happen is if you do nothing but lay around smoking. Then your muscles will get weak from lack of movement.

yes
They weaken
If astronauts don't exercise in space, weightlessness eventually causes there muscles to shrink?
the absence of the gravitational force or field in space causes the astronauts to become weightless
Weak muscles.Protein deficiency can lead to weak muscles.
