Answer:

The characteristics that are used in order to classify the stars on the Hertzsprung-Russell diagram are size, density, temperature, and absolute brightness.

The only correct answer in this case is B - a stroke.

None of the other answers could be counted as correct here.

What will occur to an Elodea cell, Euglena Cell, and a Paramecium cell when placed in a soap solution or a 5% NaCl solution
Dafna11 [192]

Plasmolysis will occur to an Elodea cell, Euglena Cell, and a Paramecium cell when placed in a soap solution or a 5% NaCl solution.

<h3>What is Plasmolysis?</h3>

This is referred to as the process in which cells which are present in an organism lose water molecules when they are placed or in contact with a hypertonic solution.

The hypertonic solution has a higher solute concentration which leads to the water in the cells moving to this area of higher concentration via the process known as osmosis. This then leads to shrinking of the cells and can also be referred to as plasmolysis.
