Name and describe all of the weather fronts.
Yakvenalex [24]

Answer:

four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

a air front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.

A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.

Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.

Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm

Based on the demonstration and your microscopic investigation, which of the three solutions is hypotonic to the red blood cells?
r-ruslan [8.4K]

You have given no demonstration based on your microscopic investigation so I cant tell you the answer to the question. I will try to help you by elaborating how to decipher..

Three terms hypotonic, hypertonic and isotonic are used when referring to two solutions separated by a selectively permeable membrane.

The hypertonic solution has a great concentration of OAS than the solution on the other side of the membrane. It is described, therefore, as having a great osmolarity. The hypotonic solution has a lower concentration of OAS, or osmolarity, than the solution on the other side of the membrane. When the two solutions are at an equilibrium, the concentration of OAS being equal on both sides of the membrane, the osmolarities are equal and are said to be isotonic.

The net flow of water is from the hypotonic to the hypertonic solution. When the solutions are isotonic, there is no net flow of water across the membrane.

If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells.

So, look at the information and data you have on your microscopic investigation and use these guidelines to tell you which is which.
