If a swimmer cuts his foot on a seashell while wading in the ocean and bleeds into the seawater, his erythrocytes will shrink. W
Tom [10]

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

Which of the following are properties of all cells? 1. Evolution. 2. Growth. 3. Communication. 4. Diferentiation. 5. Compartment
kenny6666 [7]

Answer:

option B

Explanation:

The correct answer is option B

Cells are the basic structural and functional unit of life and possess genes. These genes evolve to carry out new biological functions in the body.  

Cells undergo division and growth whether it be unicellular organisms or multi cellular organisms.  

All cells possess the property of compartmentalization and metabolism henceforth taking up nutritive material from the environment.

These nutrients are further transformed into the cell compartments and the waste produced as a result is expelled out thus forming on open system.
