Answer:
B
Explanation:
Cancerous cells grow out of control because they do not receive the signals to stop grow. This causes tumors to form, and continue growing until treated.
Auxin is the molecule which is related to the phototropism of the plants. In the mutant plants, which do not have hormone auxin, do not respond to light. It activates proton pump, and leads to the decrease in the pH of the leaf. This acidification breaks cell wall structure and cell wall become less rigid, and thus, can bend towards the light, by exerting mechanical pressure.
Let us solve first the
phenotype of this problem.
Starchy grain = AA (dominant)
Sugary Corn = aa (recessive)
AA x aa = AaAa ; AaAa
<span> A A</span>
<span>a Aa Aa</span>
<span>a Aa Aa</span>
The result of the cross is
that the progeny will become heterozygous.
<span>If there is 58 progeny
sugary, there will also be 58 starchy. It is 50%.</span>
I believe the answer is: C
I think the answer is B. But don’t trust my answer.
