Linear

Circular

(only offering low points bc people answering for high amounts)

Your B

A Double Helix

Why:

DNA is also called a three-dimensional double helix. It looks much like a twisted ladder, and the backbone of the ladder is made of sugar phosphates. The sugar in DNA -- deoxyribose -- is where the name deoxyribonucleic acid comes from.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
