Explain why maternal effects are exhibited by bicoid and nanos, but not runt and gooseberry. a. Silencer sequences for runt and gooseberry repress transcription of maternal mRNA during oocyte formation.
b. RNA transcripts of bicoid and nanos are made maternal DNA during oocyte formation, whereas runt and gooseberry are transcribed after fertilization.
c. Runt and Gooseberry proteins repress transcription of maternal mRNA, whereas Bicoid and Nanos proteins do not silence maternal mRNA transcription.
d. Enhancer sequences for bicoid and nanos promote transcription of maternal mRNA during oocyte formation.
e. Bicoid and Nanos proteins repress transcription of maternal mRNA, whereas Runt and Gooseberry proteins do not repress maternal transcription.

i think that it is c, d, and e, hope this

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
