A) a common ancestor
Homologous structures are structures that are similar in related organisms. There is a basic pattern of bones which can be inherited from a common ancestor
Answer:
An artificial heart is a prosthetic device that is implanted into the body to replace the original biological heart. It is distinct from a cardiac pump, which is an external device used to provide the functions of both the heart and the lungs. Thus, the cardiac pump need not be connected to both blood circuits.
Explanation:
Answer:
Location A
Explanation:
Coastal areas have milder temperatures since they are close to water and water retains heat better than land (it's harder to warm it up and harder to cool it down). Due to this property of water, the location with the least temperature fluctuation would be the answer. Location A has the smallest range between the highest and lowest annual temperatures, making A the best answer choice. I hope I helped and that it's not too late for you.
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.
