Answer:
- The mRNA code for each type of amino acid is a sequence of <u>three</u> nucleotides, called a codon.
- mRNA codon that codes for the amino acid Phe es UUU.
Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
- <em>An amino acid can be encoded by more than one codon.
</em>
- <em>From these combinations the three STOP codons are obtained.
</em>
A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.

<em>Earth is actually composed of three major parts or layers: the solid earth (which includes the parts near or at the surface, the asthenosphere and lithosphere), the atmosphere (the blanket of air that envelopes the earth), and the hydrosphere (the water parts, including ocean, streams and air moisture).</em>

Explanation:
- stomata
1 (a) Carbon dioxide enters stomata while water and oxygen exit, through a leaf's stomata they allow carbon dioxide in, but they also let precious water escape.
1 (b) Plants use carbon dioxide, oxygen and water in photosynthesis
2 Water is passively transported into the roots and then into the xylem. The forces of cohesion and adhesion cause the water molecules to form a column in the xylem
2(a)Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant
