In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.
<h3>What are dependent and independent variables?</h3>
Dependent variable is a type of variable in which a variable whose value depends on another variable while on the other hand, independent variable is a type of variable in which a variable whose value does not depends on another variable. Dependent variable is denoted by X whereas the independent variable is denoted by Y.
So we can conclude that In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.

Answer:
I am Going to say the smallest im in 8th grade and i got that right
Explanation:
T's harder to find one of the many genes involved in a polygenic trait vs. the only gene involved in a discrete trait."
<span>It is probably not very difficult to find ONE OF THE GENES involved in a polygenic trait (as this answer suggests), but it IS difficult to find ALL OF THE GENES involved in the trait. </span>
<span>This sounds like a high school Biology or first year university question - chances are they're testing your reading comprehension as much as your scientific knowledge.</span>
C. 0.1 M HCl
Explanation:
The solution with the lowest molarity is the most dilute of all.
This is why the choice is 0.1M of HCl.
Molarity is the same as concentration. The unit "M" denotes mole per liter volume of solution.
- Molarity is defined as the number of moles of solute in a give volume of solution.
- 0.1M means 0.1mole of HCl is dissolved in 1liter of solvent.
- The higher the number of moles dissolved and the more the concentration of the solution will be.
The order of increasing concentration is:
0.1M < 0.2M< 0.3M < 0.4M

The concentration by mass means that the mass of solute in a given amount of solution. So for the a), the concentration should be 17/(17+183)*100%=8.5%. For b), the concentration should be 30/(30+300)*100%=9.09%.
