Evolution is the

Biology
1 answer:
lina2011 [118]3 years ago
5 0

Answer:

Evolution is the <u>biological process</u> that happens over time in a population, giving rise to new <u>species.</u> The theory of evolution states that all organisms alive on Earth today <u>have a common ancestor</u> which lived <u>years ago</u>.

Explanation:

Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.

How does mutation relate to variation
Anastasy [175]

Answer:

Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.

Explanation:

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Which gas does not occur naturally in the atmosphere in any amount but was solely created by human activity? Support your answer
SpyIntel [72]

Answer:

Carbon monoxide.

Explanation:

Carbon monoxide is a gas that consists of an oxygen and a carbon to be able to fulfill the complete molecule, it is a potentially dangerous gas for life on this earth.

On the other hand, what differentiates it from carbon dioxide is that it has two oxygens that are coupled with a carbon to fulfill the complete molecule.

Both gases are pollutants, and produced by man, it is considered that these in high partial pressures in the atmosphere generate a mortal potential for humans since they have more affinity with the hemoglobin protein that is the human gas transporter par excellence, the which oxygenates the tissues.

If the oxygen drops in partial pressure and these toxic gases increase, the hemoglobin having a higher affinity will bind to them and toxify the human body, preventing oxygenation.
