Adult male humans generally have deeper voices than do adult female humans, which is the direct result of higher levels of testosterone causing growth of the larynx. If the fossil records ofapes and humans alike show a trend toward decreasing larynx size in adult females and increasing larynx size in adult males, then

Following are given stages of gibberellin biosynthetic
pathway;
a) Geranylgeranyl diphosphate (GGPP) is converted to
ent-kaurene via copalyl diphosphate
(CPP) in endoplasmic reticulum
b) In the endoplasmic reticulum, conversion of ent-kaurene
into GA12 or GA53 depending on whether the GA is hydroxylated at carbon 13
c) the conversion of GA12 or GA53 into other GAs in cytosol
proceeds with a series of oxidations at carbon 20
d) GA20 is then oxidized to the active gibberellin, GA1, by
a 3β-hydroxylation reaction
Which of the following is the correct statements of GA biosynthesis?
