Identify the incorrect statement regarding Multiple Ovulation Embryo Transfer Technology (MOET):

1. FSH like hormones or PMSG [pregnant mare serum gonadotropin] are used to induce super-ovulation [6 – 8 eggs rather than one per cycle] and Prostaglandins are used to regulate the duration of cycle.
2. Fresh embryos can be stored at 37ºC for 6 - 8 hours without much harm but it is recommended that the embryos are inserted into the recipient cow or frozen as soon as possible. The embryos can be stored forever in liquid nitrogen.
3. The animal is either mated with an elite bull or artificially inseminated and the fertilised eggs at 8–32 cell stages are recovered non-surgically and transferred to genetic mothers.
4. The embryos are transferred to a recipient cow whose oestrous cycle is at the correct receptive stage.

Insect resistance in host crop plants may be due to morphological, biochemical, or physiological characteristics. Identify the correct statements:

I: Hairy leaves in several plants are associated with resistance to jassids in cotton and cereal leaf beetle in wheat.
II: In wheat, solid stems lead to non-preference by the stem sawfly and smooth-leaved and nectar-less cotton varieties do not attract bollworms.
III. High aspartic acid, low nitrogen and sugar content in maize lead to resistance to maize stem borers.
