2.2.2.2 The diagram shows water molecules with the four orbitals of each oxygen atom.
Pogoy
Explain what is happening at the four oxygen orbitals, how this gives water its 'bent' shape and how
hydrogen bonding makes water a liquid under ordinary temperature and pressure conditions. Identify
the hydrogen bonds on the diagram.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. a parakeet that is heterozygous for blue feathers (dominant) is crossed with a parakeet that is homozygous for white feathers (recessive). according to the punnett square for this cross, what percentage of offspring is predicted to have blue feathers? 25 percent 50 percent 75 percent 100 percent
