Do animal cells store water?

Do animal cells store water?

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

Where does the cell store water?

Vacuole

Why does water move into a cell?

Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Is the flag still on the Moon 2020?

Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. Now, researchers have studied photos of the same areas taken at different points during the day and have observed shadows circling the points where the flags are thought to be.

Can you breathe in space?

Outer space is a vacuum. You cannot breathe in a vacuum because there’s literally no air to breathe, and if you tried, you’d be dead in about four minutes. Also, because space is extremely cold, your eyeballs could freeze solid, and even if you somehow survived, you’d be blind.

Can Thor breathe in space?

By definition, Thor can’t “breathe” in space, as there isn’t any air there lol. However, as an Asgardian he can survive a very long time in space, without breathing. Breathing is the reverse act of photosynthesis, turning sugar and oxygen into carbon dioxide and water, releasing the energy stored in the sugar.

How long would it take to die in space?

Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit — you’d die of asphyxiation or you’ll freeze. If there’s any air left in your lungs, they will rupture. See more stories on Insider’s business page.

Can you light a fire in space?

Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. It is chasing a deeper understanding of fire itself. Studying combustion in microgravity is beginning to enhance our ability to harness its power down here on solid ground.

Why does your head explode in space?

Humans don’t explode in space. Even though outer space represents a lack of air pressure, which usually counters the internal pressure in our bodies, our tissue is strong enough to handle the imbalance. Humans exposed to the vacuum of space don’t explode.

Why is fire so bad in space?

Ventilation fans on the Space Station replace natural convection and can supply the air a fire needs to burn. Under these circumstances, the fire can spread in any direction, rather than just upward. The flame’s unusual shape creates different amounts of soot, smoke or harmful gases.
