<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration.
There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>
Answer:
D. Two water molecules connected by an O-H interaction
Explanation:
Oxygen has a slight negative charge and hydrogen has slight positive charge. This creates an attraction between the two atoms which helps them bond.
Very simply, I think that they may block the sun's rays from reaching the Earth, cooling down the planet, or they may eventually end up being turned into acid rain and rain back down to the Earth.
Answer:
it's related to the factors of diffusion, in this case...
the molecule is small, the mass of it is a factor of diffusion, since it's smaller, it can diffuse quickly, since it has less weight, so it moves faster.
When the cell increases in size, the volume increases faster than the surface area, when there is more volume and less surface area, diffusion takes longer and is less effective.
