Exerćıcio 1.1. Suponha que f : R → R preserva a distância Euclidiana e fixa a origem. Mostre que: (1) f leva segmentos de recta em segmentos de recta; (2) f(λx) = λf(x) para λ ∈ R e x ∈ R; (3) f leva o ponto médio de um segmento no ponto médio da sua imagem; (4) f(x+ y) = f(x) + f(y) para x,y ∈ R; (5) 〈f(x), f(y)〉 = 〈x,y〉 para x,y ∈ R; (6) f(x) = Sx para x ∈ R, onde S ∈ M3×3 é ortogonal (ou sej...

متن کاملMolecular evolution of odorant-binding protein genes OS-E and OS-F in Drosophila.
The Drosophila olfactory genes OS-E and OS-F are members of a family of genes that encode insect odorant-binding proteins (OBPs). OBPs are believed to transport hydrophobic odorants through the aqueous fluid within olfactory sensilla to the underlying receptor proteins. The recent discovery of a large family of olfactory receptor genes in Drosophila raises new questions about the function, dive...
