The air spaces occur in Spongy mesophyll tissue.There are large spaces in a leaf because it is for storing water and carbon dioxide which will be used for photosynthesis. The large air spaces are usually found in the spongy layer of the mesophyll. The arrangement of this spongy mesophyll facilitates the movement of gases through the mesophyll. Directly beneath each stomate at the leaf surface there is usually a small air space, called a stomatal chamber, where no mesophyll cells are present. This also aids in gas exchange.

Answer:
DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
Answer:
The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.
Explanation:
Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.
The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:
- <em>Adenine</em><em> is complemented with uracil, since in RNA the thymine is substituted by this uracil.
</em>
- <em>Thymine</em><em> is complemented with adenine.
</em>
- <em>Cytosine</em><em> is complemented with guanine.
</em>
- <em>Guanine</em><em> is complemented with cytosine.
</em>
Thus an <u>uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T</u>.
