Answer 1

G . s. The mane or a llon acts as a shield which protects male's neck curug advense conditions and higha 16 the longen manes in the lions are selected by remale choice or not we can design an - male experiment. In a cages tions are kept with the bemale lions or lioness. In another two cage male lions are isolated and were not in any contact with hemale lions. They are given same type or rood at the same time. They were kept for at At least 6 . months. the end or the period we can observe that llons which are kept with lioness have longen manes because or selection by the remale ones. The nul hypothesis is here the Gthen cage where male llons are isola which may illustrata longen mane is not associated with bemale ones. lated 1 According to updated Chegg policy I only answered first question asked by you,
