If a swimmer cuts his foot on a seashell while wading in the ocean and bleeds into the seawater, his erythrocytes will shrink. W
hat does this tell us about the relative tonicities of the solutions? A) The ocean is hypertonic to the erythrocytes.
B) The erythrocytes are hypertonic to the ocean.
C) The erythrocytes are isotonic to the ocean.
D) The cell membrane is not permeable to seawater.
Answer:A) The ocean is hypertonic to the erythrocytes.
Explanation:cells shrink when placed in an hypertonic solution.
This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.
The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
Since the Hemispheres are parallel to each other in terms of seasons, the season should be winter in the south hemisphere so she she pack things like sweaters or mittens.
If warm clothes are for winter then go for it, if warm clothes are for summer then I'm sorry.
I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
"Animals will migrate to other regions in search of food" Whenever an area in a forest is cleared up to build a road or because of any other reason the habitat of the animals residing there is destroyed.
