Answer: The salinity of the water increases
Explanation: When the moves from equator to the polar region the salty water starts freezing, the ice that is formed is not salty means it is a source of freshwater.
So, the water that reaches the poles becomes ice and the salinity of the water increases. This is because the poles are colder as compared to the other parts of the globe. The water becomes ice there and its salinity increases.
Answer:
D. 0.5 ft
Explanation:
Using the scale :
1 : 4000
This means that an altitude of 4000 feets is represented by 1 unit in the model.
Hence,
1 feet in model = 4000 feet actual altitude
Given an actual altitude of 2000 feets above ground level ;
Feets in the model will be x
1 feet = 4000 feet
x = 2000 feet
Cross multiply :
4000x = 2000
Divide both side by 4000
4000x / 4000 = 2000/4000
x = 0.5
Hence, 2000 feets above ground level corresponds to 0.5 feets in model
The correct answer is a semi-permeable membrane.
A semipermeable membrane refers to a layer, which only allows some of the molecules to pass through. A semipermeable membrane can be both artificial and biological. The speed of passage relies on the concentration, pressure, and temperature of the solutes or molecules on either side, as well as the permeability of the membrane to each solute.
On the basis of the solute and the membrane, permeability may depend on the size of the solute, properties, solubility, or chemistry. A semipermeable membrane illustrates a membrane, which permits some of the constituents to go through, while the selectively permeable membrane opts for the substances that pass through.
