how the black holes are generated and what are its effect ?

Let f : G → H and g : H → K be homomorphisms of groups. Show that g ◦ f is a homomorphism from G to K.

In H-NMR, which H would show up most downfield?

What trend in the H-X-H angles in the sequence from methane to water would VSEPR theory predict, and why? Compare and comment on your calculated sequence.

H­₂O: Average angle: 107.69336°

The force constant of the H-H bond is about 510 Nm^-1. How much work is needed to stretch such a bond by 20 pm? Please show all steps for calculations.

A dominant allele H at the H locus reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the hairy phenotype. However, S also is lethal in the homozygous (S/S) condition.

A. What is the phenotype of a dihybrid (H/h; S/s)?

B. What is the phenotype of an H/h; s/s fly?

C. Suppose you mated a H/h; s/s female with an h/h; S/s male. What phenotypic ratios would you expect in the living offspring? ****For part C I got 2/16 hairless, 7/16 hairy, and 7/16 not living

D. A true-breeding plant of genotype A/A; B/B; c/c is crossed to a truebreeding plant of genotype A/A; b/b; C/C. What would be the genotype and phenotype of the F1?

What is python theory?
