Explanation:
The water must be cooled. Cooling water means the kinetic energy of the water molecule is reduced. Bombardment with the solute molecules reduces. In addition, The inter-molecular spaces between the water molecules reduce and therefore the number of solutes that can be accommodated in the inter-molecular spaces reduces. This is how saturation point is reached. Therefore as you coll the solution, the solute molecule precipitate from the water.

When water molecules
diffuse through a cell membrane this process is called the osmosis. Water
molecules are extremely small and because of this they can slip freely through
the gaps between the phospholipids in the cell membrane. And as a result, water
molecules can constantly move back and forth though the cell <span>
membrane. This movement of water has a very important
function and that is it enables cells to absorb water. </span>
Now for a movement of
water molecules to happen, there should be a concentration gradient in the surrounding.
That is, the amount of water in one side must be different on the other side.
<span>For water to diffuse
INTO the cell, the amount of water outside the cell membrane should be larger
than the amount of water inside the side.</span>
Answer:
Sporophyte generation; gametophyte generation; sperm cells are transported by water to egg cells; spore are transported by air.
Explanation:
> Both ferns and mosses have gametophyte generation followed by sporophyte generation.
> Both are spore bearing and the spores are transported by air.
> The sperm finds the egg cell by chemotaxis and require water for movement.
> They require moisture to thrive.
Answer:
<h2>C-A-B</h2>
Explanation:
Given
As given: A and B are 30 map unit apart
A and C are 15 map unit apart
B and C are 45 map unit apart
So the sequence of genes : according to the map unit distance is:
C-A-B
C-15-A-30-B
C-A=15
A-B=30
C-B= 45.
correct order of genes is C-A-B

Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
