Answer: 50% will have short hair
Explanation: The allele for a heterozygous dominant short hair is ( Ss ) and the allele for the homozygous long hair which is the recessive trait is ( ss ).
If we cross these alleles the results will be.
s s
S Ss Ss
s ss ss
The results will have 50% Heterozygous dominant short hair and 50% Homozygous recessive long hair.
Hello!
A reaction where the products have less chemical potential energy than the reactants had originally is called an exothermic reaction. Although the scientist didn't observe light or sound, an observation that would support her prediction is the rise in temperature after the reaction has completed. Exothermic reactions release energy in the form of heat, and the temperature would rise in an exothermic reaction.
Have a nice day!
Answer: at relatively low temperatures.
Explanation:
According to Gibbs equation;
= Gibb's free energy change
= enthalpy change
T = temperature
= entropy change
A reaction is spontaneous when = Gibb's free energy change is negative.
Thus 
Thus the reaction is spontaneous or is negative only when 
Thus the reaction is spontaneous at relatively low temperatures
