Since the air is a great thermal isolator, the windows prevent heat exchange better than one made out of a single thick sheet of glass. The air between the thin blankets is not moving around and will form an isolating layer that acts exactly like another blanket, thus improving the thermal isolation
Answer:
The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
Explanation:
The choices can be found elsewhere and as follows:
A. mature leaves
B. shoot apical meristem
C. cell elongation zone
<span>D. axillary buds
</span>
I think the correct answers are option B and D. It would be at the shoot apical meristem and the axillary buds that <span> a vascular plant would you expect to find totipotent cells. Hope this answers the question.</span>
