Sexual reproduction creates variaty that asexual reproduction cannot provide. If we were all asexual, that means that there are very little variaty(the little part is caused by mutation) and that we would all look alike and be alike. The problem with this is that if a disease spreads in the population that is lethal to one person, then it will be lethal to everyone in that population(unless there was a mutation). Our being able to reproduce sexually has made it easy to not die by a disease that might be lethal to one person.
Mutations contribute to genetic variation within a population by introducing new alleles. These new alleles can lead to different traits or characteristics, increasing diversity within the population. Over time, natural selection can act on this variation, influencing which traits become more or less common.
When the blue ink is added, it (eventually) spreads evenly throughout the water through diffusion. See related links below for more information.
An epidemic is a disease that spreads rapidly and affects a large number of people within a particular region or population. If the epidemic spreads across countries or continents, it may be classified as a pandemic.
When a drop of oil falls on paper, the paper absorbs some of the oil while the oil spreads out and is eventually absorbed by the paper due to capillary action. The oil can leave a stain on the paper as it is absorbed.
no of course not. cancer is caused by a mutation in a cell that spreads and not in a sex cell witch is how genes are passed on.

Viruses have a big affect on the body system and it spreads quilky because it does
Otherwise it spreads, becomes an epidemic and wipes out the human population Next question please!
you die from smoking because most cigarettes have tar in them and that tar bulids up in your lungs and eventually you get lung cancer and that quickly spreads around and infects your brain and eventually it stops your brain and you die. TAH
Poorly planned development that spreads a city´s population over a wider and wider geographical area.

As the sound spreads over a larger and larger area, it naturally gets weaker and weaker. Also, the sound energy will eventually be absorbed, i.e., it will be converted into other forms of energy, such as heat.
Mutations are essential to evolution. Every genetic feature in every organism was, initially, the result of a mutation. The new genetic variant (allele) spreads via reproduction, and differential reproduction is a defining aspect of evolution. It is easy to understand how a mutation that allows an organism to feed, grow or reproduce more effectively could cause the mutant allele to become more abundant over time. Soon the population may be quite ecologically and/or physiologically different from the original population that lacked the adaptation. Even deleterious mutations can cause evolutionary change, especially in small populations, by removing individuals that might be carrying adaptive alleles at other genes.
