What causes variation in human beings?
the variations in genes, genes of sexually reproducing organisms will vary due to crossing-over of genes, mutations, and adaptations. In asexually reproducing organisms genes will vary through adaptations and mutations.
What are the occasional mistakes in copying DNA called and why are they significant for evolutionary change?
Mutations. They, when beneficial, provide variations of organisms genomes for natural selection. Beneficial mutations may confer a slight reproductive advantage to the organism so that genes " promoted " into the next generation change the allele frequency of the population causing evolution.
What causes mutations in bacteria?
Pretty much the same process that causes mutations in any organism. The replication of the genetic code is not perfect and copying mistakes are made where one bases is substituted for another, or a whole string of bases is shifted in a frame shift. Google ' mutation. '
A sudden permanent change in a organisms dna called?
A sudden permanent change in an organism's DNA is called a mutation. Mutations can occur spontaneously or be induced by factors such as radiation or certain chemicals, leading to genetic variations that can impact an organism's traits or characteristics.
How does an organism get variation?
Organisms can acquire variation through genetic mutations, which are changes in the DNA sequence. These mutations can occur spontaneously or be introduced through processes like recombination. Additionally, environmental factors can also contribute to variation by influencing gene expression and phenotype.

What living things have mutations?
All living "Organic" things or life forms will mutate as a process of natural selection. This ensures that the strongest species survives. Without mutations, organisms would not evolve or improve their success to survive!
What scientist showed that organisms not grow spontaneously?
Louis Pasteur demonstrated through his experiments that organisms do not arise spontaneously, but rather from pre-existing living organisms. This work debunked the theory of spontaneous generation and supported the idea of biogenesis.
Is 'mutations are beneficial to organisms' a true statement about mutations?
Not always. Mutations can have either beneficial, neutral, or harmful effects on organisms. Whether a mutation is beneficial or not depends on how it impacts the organism's ability to survive and reproduce in its environment.
How can nuclear radiation effect living organisms?
Nuclear radiation can damage cells in living organisms, leading to DNA mutations, cell death, and tissue damage. It can cause acute radiation sickness or lead to long-term health effects such as an increased risk of cancer or genetic mutations in future generations. The extent of the impact depends on the dose, duration of exposure, and type of radiation.
Can mutations add information in organisms?
mutations in dna can be advantageous and lead to charecteristics that help a person survive or increase it chances of survival.
What causes DNA variation in organisms?
Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.
Does inducing mutations produce organisms with beneficial traits?
Inducing mutations can result in organisms with beneficial traits, as some mutations may lead to new desirable characteristics. However, the majority of mutations are neutral or harmful, so the chances of producing a beneficial trait are relatively low. Additionally, the process of inducing mutations can also introduce unwanted genetic changes that may negatively impact the organism.
