T/F: FADH2 adds its electrons to complex III while NADH adds its electrons in complex

Observe the seedlings growing below which have a loss of function mutation in the
ethylene receptor. Which of the following statements are TRUE regarding this mutant's
growth response NOT being related to a triple response? Select one response
I,II,III,IV,V

I. This mutant will not respond to the exposure of ethylene under any circumstances.
II. This mutant has a constitutive activity where it leads to the activation of kinase, which
is important for the triple response.
III. This mutant has a constitutive activity where it leads to the inactivation of kinase,
which is important for the triple response.
IV. If this mutant is treated with aminoethoxyvinylglycine (ethylene synthesis inhibitor),
this mutant will be able to undergo triple response.
V. If this mutant is treated with aminoethoxyvinylglycine (ethylene synthesis inhibitor),
this mutant will not respond to the treatment and not undergo triple response. - Answer-
I,III,V

Three groups of Arabidopsis seedlings are subjected to a short burst of ethylene. Group
A is comprised of ethylene-insensitive (ein) mutants. Group B consists of constitutive
triple-response (ctr) mutants. Group C is also subjected to high levels of abscisic acid.
Group D serves as a control (wild type) and receives the ethylene treatment. Which
group is likely to be the tallest after a few days of the treatment? - Answer-Group A

Today's corn plants evolved from an ancestral plant known as teosinte. One genetic
change that occurred in modern corn is a mutation in the regulatory DNA associated
with the gene tb1. As a result of this change, teosinte has low levels of tb1 expression,
and corn has high levels of tb1 expression. High levels of tb1 expression in plant axillary
buds inhibit the growth of branches, leading to tall, unbranched corn plants in farmer's
fields. In contrast, teosinte is highly branched. The tb1 gene is also required for the
development of ears of corn on the plant; both modern corn and teosinte produce ears
of corn that carry the seeds of the plant. Based on this information, which of the
following statements is NOT true?
