1. These four factors can effect ways evolution occur:
<span>1.) Mutation
2.) selection
3.) Gene Flow
4.) Genetic Drift
2. </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.
In population genetics, gene flow is the transfer of alleles or genes from one population to another.
<span>Genetic drift is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>
Sex cells are haploid, therefore it has half the number of chromosomes (23) while other cells have 46
<span>The first enzyme is reverse transcriptase. The concept of
reverse transcription was much unknown at first. A reverse transcriptase is an enzyme used to
generate complementary DNA (cDNA) from an RNA template, a process termed
reverse transcription. It is mainly associated with retroviruses. As it
contradicted the central dogma of molecular biology, which states that DNA is
convert into RNA, which is then translated into proteins.</span>
It means that they are classified into 2 different categories.
Answer:
<em>The correct option is b) the uses an area of land can be put to
</em>
Explanation:
Zoning laws can be described as guidelines which characterize how any municipal area should be divided. Zoning laws are laws which are to be followed to make zones in an area. For example, the making of residential or industrial zones. The type of land or zone determines whether permission should be given to develop the zone or not. Zoning laws determine which area should be ideal to construct what buildings and how a particular zone should be utilized.
