Control group will be at a room temperature water. The experimental will be tested in cold and warmer waters.
Independent variable: change of water temperature.
The data will be the amount of growth in which the water fleas population increases or decreases, a bar graph would work.
I believe doubling the speed of the marble will increase the kinetic energy when it rolls down a ramp
Sorry if wrong

<h3>
What is karyotype?</h3>
A person's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order. A karyotype can be used to check for chromosomal number or structural problems.
Males and females may have different karyotypes. For instance, human females have two X chromosomes while males have an X and a Y chromosome in their karyotype. Body (somatic) cells and egg and sperm cells have different karyotypes (gametes).
