Hope it helps!
Answer:
The correct answer would be - option D) UAC.
Explanation:
By the process of the translation mRNA turns into protein as mRNA is considered as blueprint of the protein. During translation tRNA contains anti-codons or amino acid this anti-codon is correspond to the codon of mRNA.
The anticodon of tRNA which is present at the accept site or anticodon of tRNA molecule is complementary to the codon present in the mRNA which means A pairs with U and G pairs with C only.
Thus, the correct answer would be - option D) UAC.

like david said just wash it lol
Explanation:
The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.
Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.
The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.
Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.
Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
