How is salinity affected

A/ evaporation increases

B/ freezing increases

C/ melting increases

D/ precipitation increases

The earth is comprised of about 70% of water, of which more than 95% is saline in nature. This salinity of ocean water increases with the increasing rate of evaporation. As the water evaporates in the region where there are abundant salt concentrations, only the salt particles are being left out. This saline water is denser than the freshwater. The salinity of the ocean water is again counterbalanced by the occurrence of other processes such as precipitation, fresh water from the rivers and melting of ice in the polar region.

So, salinity can be affected in the following conditions as given below-

(A) Salinity is directly proportional to the rate of evaporation.

(B) Salinity is inversely proportional to the rate of freezing.

(C) Salinity is inversely proportional to the rate of melting.

(D) Salinity is inversely proportional to the rate of precipitation.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
