Answer:
c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
Explanation:
A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>
I annexed an image of the DNA structure.

Answer:
I am going to answer the questions in one brief summary of fossil fuels.
Fossil fuels are non-renewable, meaning one day they will run out.
Fossil fuels are reliable, meaning rain or shine we can use them.
Fossil fuels emit greenhouse gases, causing our world to warm up.
Answer:
The options are
A. secondary structure ... hydrogen bonds
B. secondary structure ... peptide bonds
C. tertiary structure ... hydrogen bonds
D. primary structure ... covalent bonds
E. tertiary structure ... covalent bonds
THE CORRECT ANSWER IS A.
A. secondary structure ... hydrogen bonds
Explanation:
The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups
-NH and C = O
At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.
The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.
The dialysis tubing and cell membrane are similar in the fact they protect the cell. The tubing as well as cellmembranes are selectively permeable, they control the movement of substances in and out of the cell. Starch molecules are larger than glucose molecules.
