In human, Oogenesis in comparison to spermatogenesis is different in that Oogenesis does not complete meiosis until after fertilization, but spermatogenesis is complete before the sperm leave the body. Oogenesis is the process by which the female gametes, or ova are created in the female's ovary. Spermatogenesis is the process in which males synthesis sperms. The two process are part of gametogenesis which involves meiosis type of cell division, in which a diploid cell divides into four haploid daughter cells.

2. Different beaks
3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. mutation, gene flow, genetic drift, and natural selection.
Mutation creates new genetic variation in a gene pool.
Gene flow and genetic drift alter allele frequencies in a gene pool.
5. The finches have few predators / competition for food.
Explanation:
I believe the correct answer would be C.) The 3’ end has a free phosphate group
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
