Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.

Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
Oh, we actually did a similar project in my biology class!
I looked at your punnet squares and they all looked right to me, so I will just explain how to find the genotype and phenotype.
Ok, so let me explain that for genotype they mean the letters, so for example if the penguin has a dominant trait, the genotype could be Ff, or recessive could be ff. By phenotype they mean the trait expressed, so if the penguin is dominant for freckles, the phenotype would be has freckles.
Now I don't know what your teacher wants you to do, but in my class we just flipped a coin to decide whether we would use the dominant or recessive trait.
Hopefully that clears it up a little bit for you :)
