The evolution of sexual reproduction is a great puzzle in modern evolutionary biology. Many groups of eukaryotic organisms, especially most animals and plants, reproduce sexually. The evolution of sex between two organisms of the same species contains two related but different themes: its origin and its maintenance. However, since hypotheses for the origin of sex are difficult to test experimentally, most of the current work has focused on the maintenance of sexual reproduction. Biologists, including W. D. Hamilton, Alexei Kondrashov, and George C. Williams, have proposed various explanations for how sexual reproduction is maintained in a large set of different living things.
Answer:
The CPT codes vary according to the country where you live, such as in Peru, the CPT code of the injury you name is 1 D 99 A 4 A.
Explanation:
That is why so that you know exactly what code it is, clarify in the question where I needed the CPT from.
I would say photosynthetic bacteria are the most important, because if they disappeared most of the oxygen in the atmosphere wouldnt be here and complex life like humans wouldnt exist
Answer:
Translation
Explanation:
The translation is the process during which the nucleotide sequence of the mRNA is read in the form of genetic codes. The nucleotide sequence of mRNA is complementary to the template DNA strand. According to the sequence of the nucleotides in the mRNA, the amino acids are added in a specific order to make the polypeptide chains. The process occurs on ribosomes. The ribosomes move along the mRNA to read its sequence and the tRNA brings are amino acids to be added to the polypeptide chains.
