By reversing the direction of the current.
The effects of exercise on heart rate can be studied by analyzing the number of heart pumps according to physical exercises, while control variable is room temperature.
<h3>What is an independent variable?</h3>
An independent variable is any variable that isn't changed along the experimental procedure, while the dependent variable is modified by the conditions.
The sample size must be statistically significant (N sample size higher than 50 individuals) and a number of trials at least two to compare results.
In conclusion, the effects of exercise on heart rate can be studied by analyzing the number of heart pumps (dependent variables) according to physical exercises (independent variable), control variable is room temperature.

Answer:
The area will experience a short-term economic boom
The area will experience a downturn once all of the available resources are mined
Explanation:
Hope this helps
The offspring will inherit one allele from each parent.
<h3><u>Explanation</u>:</h3>
The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.
One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.
The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.
Now as they are crossed the offsprings will have genetic combination of Yy.
This is seen that the offsprings carry one allele from both the parents.
