An astronaut is in a sleeping bag attached to a wall. When astronauts sleep in space, they sleep in small cabins or in sleeping
Mnenie [13.5K]

Answer:

Free fall.

Explanation:

When astronauts sleep in space, they sleep in small cabins or in sleeping bags that are attached to the wall or ceiling of the station. Everything is weightless as there’s no gravity in space. So while sleeping there is a chance of floating around and bumping into things. Astronauts use sleeping bags that can be tethered to the wall or ceiling to solve this problem. Also the tethered sleeping bags provide a normal sleeping environment to the astronauts  as they can feel pressure on their back and head.  Their sleeping cabin is well ventilated as they can wake up with breathing trouble as a result of the inhalation of their own exhaled carbon dioxide which formed around their heads as a bubble. They use earplugs and a sleep mask to block the noise and light and can sleep vertically or horizontally. Compared to earth, sleeping is a bit different in space.

Both parent's genotype is Bb because they are hairless and alive.

If it has a homozygous dominant genotype (BB), the dog will die in utero.

If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.

If it has a homozygous dominant genotype (bb), the dog will have hair.

The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

Hope this helps! <3

A human lost at sea without fresh drinking water is effectively lost in an osmotic desert. why would drinking salt water be harm
Grace [21]
Drinking salt water is harmful because it messes up the salt concentration in each of your red blood cells. It over loads the salt in it and causes the cell to swell up and burst due to it trying to let in more water to balance the salt concentration out.
