Answer:
Hypothesis: If plants do not get enough water, then they will not grow.
Indpendent Variable: amount of water.
Dependent variable: height/growth of plant
Constants:
- same amount of sun
- same plant
- same amount of shade
- same pot
- same soil
- same water
- same temperature
Explanation:
Hope that this was the type of example that you're looking for, just a simple experiment that is a good way to show how the scientific method works. Good luck!
Answer:

Explanation:
Let "XB
" represents the dominant allele for no baldness
and let "Xb
" represents the recessive premature male-pattern baldness
Genotype of affected male is Xb
Y
Genotype of heterozygous female XB Xb
Now when the above male and female are crossed, the following offspring are produced
Xb
Y * XB Xb
XB Xb, XB Y, Xb Xb, Xb
Y
Since, this Xb allele is only expressed in males, therefore females will not be affected by it
Hence, out of 4 offspring only one male offspring with "XbY" genotype will have premature baldness
