Why is the rate at which mutations occur rather slow?
Asked in Botany or Plant Biology, Genetics
What are three main ways that variations in a genotype arise in a population?
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.

Asked in Koalas
Do koalas have a slow metabolism?
Yes. A slow metabolism is one of the koala's adaptations Koalas have a slow metabolic rate which is required for them to digest the eucalyptus leaves on which they feed. Eucalyptus leaves are very fibrous and rather low in nutrition, so the fact that the koala has a slow metabolic rate means it can keep the food within its digestive system for as long as possible in order to maximise the energy that can be extracted from the leaves. This slow metabolic rate also means the koalas sleep for more time each day in order to conserve energy.
