Answer:
DNA is also called deoxyribonucleic acid which is made up of two chains which wind around each other to form a double helix model. The 2 DNA strands are also called polynucleotides and they are made up of monomeric units known as nucleotides. These nucleotides are made up of one of four nitrogen-containing nucleobases: cytosine, guanine, adenine and thymine, a phosphate group, and sugar known as deoxyribose.
Nitrogen bases present on the two separate polynucleotides strands are bound together with the help of base pairing (such as adenine with Thymine) and with hydrogen bonds to form double-stranded DNA.
So, adenine in DNA is complementary to thymine.
Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over.
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!

Explanation:
From what I know this could be wrong, but in the four stages of natural selection, the first step is overproduction, the second step is adaptation, and the third step is competition or survival of the fittest. This means that only the organisms with the best adaptations for their surroundings will survive. COULD BE WRONG SORRY IF IT IS
