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:
The distribution of chloroplasts in each algae cell was approximately the same.
The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.
Explanation:
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
