In _______ a population isolated by a geographic barrier becomes a new species as it accumulates changes by natural selection or
Mashcka [7]

Answer:

The correct answer is allopatric speciation.

Explanation:

Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.

So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.

The ribosome slides one codon down the mRNA. <u> Option B.</u>

Transcription is the technique of the producing of RNA from DNA. Translation is the gadget of the formation of protein from RNA. Translocation is the motion of substances in vegetation from the leaves to other elements of the plant. Translation takes area at the ribosome, which includes rRNA and proteins. In translation, the instructions in mRNA are take a look at, and tRNA brings the perfect collection of amino acids to the ribosome.

Metabolic techniques, particularly the products of photosynthesis are transported from the leaves in which they may be formed to unique factors of the plant. This shipping of soluble photosynthetic products is known as translocation and takes vicinity in a part of the vascular tissue called the phloem.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats
marta [7]

Answer:

0.1 x 0.3 = 0.03 = 3%

Explanation:

Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations).  In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.
