1. What type of response will a red blood cell have when placed in a hypertonic solution?
GalinKa [24]
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.

When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.

Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)

Since water flowed out of the cell, the cell lose water and shrinks.

Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.

So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.

The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.

The climate of Houston, Texas is humid subtropical, with a temperature
Talja [164]

The culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.

<h3>Arctic outbreak</h3>

"Bursts" of cold air like this are usually confined to the Arctic region thanks to a series of low-pressure systems, says the NWS. However, one of these waves advanced through Canada and "escaped" to the US.

According to experts heard by Reuters, it is a vast mass of icy air in the atmosphere, which brings with it frigid temperatures - which can be prolonged if storms form.

From this information we can conclude that according to the US Weather Service (NWS), the culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.
