The most likely hormone released to Gina and her body deal with this dangerous and frightening situation is the adrenaline or epinephrine.
Explanation:
Adrenaline, also called <em>epinephrine</em>, is a <u>neurotransmitter</u> secreted to the bloodstream by the adrenal gland. <u><em>Under pressure or stress</em></u>, it is considered to be a survival hormone, as it <em>triggers physiological changes </em>in the body necessary to be fast or strong.
Adrenaline increases heart beating, blood pressure, stimulates breathing and dilation of the respiratory tract. It also increases glucose concentration in blood. It is responsible for the attack, defend or escape reactions.
For this you would use a punnet square (ill try my best to show it while typing)
heterozygous means different, so with the purple flower youd get the gene shown as Pp and put it into the punnet square
P p
P PP Pp
p Pp pp
given the possibilities in the punnet square the genes with at least one P is going to be purple and the genes with 2 "p"s are going to be white
so you would have
25% Dominate Homozygous Purple
50% Dominate Heterozygous Purple
25% Recessive Homozygous White
