Frozen water (ice) has less density than liquid water.

Biology
1 answer:
WARRIOR [948]3 years ago
3 0
The ice has less density than liquid water, so it floats on the water surface. Therefore during the winter all the lakes and rivers are frozen only at a top. Deeper layers of water are cold, but still liquid and it allows fish and other organisms to survive. Moreover, the ice cover provides temperature isolation so liquid water beneath the ice has more or less constant temperature (around 4 dgr Celsius)

Why would too much salt intake cause someone to develop high blood pressure?
aleksandrvk [35]

The right answer is A) Salt in the bloodstream causes fluids to enter the blood from surrounding cells, due to osmosis.

The circulatory system of the body is a highly flexible vascular system, which has the ability to open and distend new capillaries and veins in order to cope with an increase in fluid volume.

The term "Higher blood pressure" implies that an excess of salt leads to the retention of additional fluid within the arterial circulatory system, which would cause an increase in blood volume and add pressure to the walls. arteries.

inysia [295]

Answer:

<em>Geographic isolation</em>

Explanation:

Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.

The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.
