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.
Explanation:
Carbon dioxide water and energy are the typical products of the breakdown of which type of molecule
The answer is false.
an available phosphate group would be found at the 5' end of the nucleotide labeled A. The 5′-end of a DNA contains a phosphate group that is attached to the 5′ carbon of the ribose ring and that A phosphate group permits ligation of two nucleotides ( phosphodiester bond).
The answer is “the conditions are right for severe weather but it is not occurring yet”
