The recommended method for disposing of the insect that causes lyme disease is to drop it and 70% alcohol or diluted bleach.
Lyme disease is a disease that is caused by the bacterium Borrelia burgdorferi and is transmitted through the bite of infected black legged ticks in humans. Its symptoms include fatigue, headache, fever and a characteristic skin rash.
Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population.
Usually it is expressed as a proportion or a percentage.
In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.
The frequencies of all the alleles of a given gene often are graphed together as an allele frequency distribution histogram.
Population genetics studies the different "forces" that might lead to changes in the distribution and frequencies of alleles - in other words, to evolution.
Besides selection, these forces include genetic drift, mutation and migration.
Answer:
By cooling the heart, its need for oxygen is reduced. This allows surgeons to work on the heart for two to four hours without damaging the heart tissue.
