4. Some animals, however, such as termites, can digest cellulose with the help of a gut protist (a tiny animal) called Trichonympha. There are between 300 and 1,3000 glucose molecules in a
single cellulose molecule. If the average size of a cellulose molecule is 1,000 glucose molecules,
on average, how many water molecules would have to be present for a Trichonympha protist to
successfully digest it into all 1,000 glucose molecules'

Which of the following factors would not contribute to allopatric speciation? a) a population becomes geographically isolated from the parent population.b) the separated population is small, and genetic drift occurs.c) the isolated population is exposed to different selection pressures than the ancestral population.d) different mutations begin to distinguish the gene pools of the separated populations.e) gene flow between the two populations is extensive.
