Answer:
The correct answer will be option- permits complementary base pairing
Explanation:
DNA contains four types of nitrogenous bases which pair with one another, identified by Erwin Chargaff.
Chargaff suggested that adenine binds thymine forming two hydrogen bonds and cytosine binds guanine forming three hydrogen bonds.
This base pairing between the complementary groups is known as a complementary base pairing which plays an important role in DNA.
The complementary base pairing allows the formation of the helical structure of DNA, the base pairs to be arranged in most energetically and favourable way and replication and transcription processes.
Thus, permits complementary base pairing is the correct answer.
The method used above involves the determination and comparison of the genes of the three species of finches. So, the answer is
<span>(3) Obtain molecular evidence from all three species and identify similarities.
</span><span>The genetic makeup of the three species will show different similarities that can be used to relate the evolution of the different species.</span>
Answer: B. reforestation
Reforestation is the process of growing plants and trees in an area on large scale in order to create land a forest reserve which can allow the growth and abundance of floral and faunal species in future. Reforestation is the biodiversity restoration method that the biologist should use to meet their goals like : recreation of habitats for wildlife in a particular area, help against climate change as plants are the fixers of atmospheric carbon utilize this for photosynthesis and prevents the raising of atmospheric temperature.
<span>The diploid generation of the plant life cycle always produces spores. Diploid is itself a spore producing phase of an organism. These diploid cells produce haploid spores through meiosis. Egg in the ovule is fertilized by sperm that is released by pollen grains. This fertilization gives embryo that gives seed to sprout.</span>
No matter what the cell type, prokaryotic or eukaryotic, plant or animal, the cell membrane forms a protective barrier between the exterior environment and the interior of the cell.
