Both of the following are correct: They have extremely short generation times and large populations; They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer.
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
Carbohydrates are the body's primary and immediate source of energy.
The primary source of energy used to form an ATP molecule is the breakdown of glucose through cellular respiration.
The most important source of variability in bacteria is mutation.
Prokaryotes rely more on mutations for generating genetic variations because they reproduce asexually, so mutations are a primary source of genetic diversity. Eukaryotes reproduce sexually, which introduces genetic variations through meiosis and recombination, reducing the reliance on mutations for generating diversity.

The primary original source of genetic variation in a population is mutation. Mutations are changes in the DNA sequence that can lead to new genetic variations in populations, providing the raw material for evolution to occur.
Often in reproduction, broken chromosomes are formed by random natural factors. When these combine with other chromosomes, new characteristics can be formed which are different from the Natural Chromosomes.
It is a primary source.
This is a primary source.
A picture can indeed be a primary source.
it is a primary source
It is a primary source because it was taken at the time.
Human recombination is a significant source of genetic variation.
