Answer:
C. Nucleic Acids arranged in a double helix.
Explanation:
The structure of DNA is best described as a double helix. DNA has a sugar phosphate back and nucleotides connected by covalent bonds. Together, it looks like a twisted ladder which is also known the double helix.

Answer:
207 ° C
Explanation:
De;
P1 / T1 = P2 / T2
Luego;
P1T2 = P2T1
P1 = I presión inicial = 7.5 atmósferas
T1 = temperatura inicial = 15 ° C + 273 = 288K
P2 = presión final = 12,5 atm
T2 = temperatura final =?
T2 = P2T1 / P1
T2 = 12,5 * 288 / 7,5
T2 = 480 K -273
T2 = 207 ° C
Answer:
Phospholipids
Explanation:
The plasma membrane has a lipid bilayer in which proteins are embedded. The chemical composition of phospholipids of the membrane greatly influences the fluidity of the membrane. The length and saturation of lipid tails affect membrane fluidity. Phospholipids with short lipid tails having less than 16 carbon atoms increase the membrane fluidity as compared to the phospholipids with long tails. Phospholipids with saturated fatty acid tails make the membrane rigid while the ones with cis unsaturated fatty acid tails increase the membrane fluidity by their less dense packing.
