Answer:Plate tectonics explains why Earth's continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. It has gained widespread acceptance among scientists
Explanation:
The nurse found a transitory
short and long term memory loss and confusion. Electroconvulsive therapy is a kind of a
procedure that done under general anesthesia,
this procedure can changes the brain chemistry by giving the patient a
small electric current that will pass through the brain intentionally making a
small fast seizure. That’s why there are some side effects is memory loss, some
memory problem improve after the treatment ends.
Polygenic inheritance is determined by multiple Genes <span>located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.

The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.
