Answer:
It best describes the structure of a DNA molecule. ... Nevertheless, DNA is a double helix structure which contains nucleobase which is either adenine (A), cytosine (C), guanine (G), or Thymine (T) along with deoxyribose a monosaccharide sugar and phosphate group as well.
Explanation:
It best describes the structure of a DNA molecule. ... Anyway, DNA is a double (twisted-ladder shape) structure which contains nucleobase which is either adenine (A), cytosine (C), guanine (G), or Thymine (T) along with deoxyribose a monosaccharide sugar and phosphate group also.
Answer: D. Autotrophs produce organic molecules
During photosyntheis, plants make sugar(an organic molecule and a type of carbohydrate). Photosynthesis occurs in autotrophs only, the organisms which are able to make their food like plants. Plants take air and water and produces glucose in presence of sunlight( a photochemical reaction). The product of the reaction is glucose which is one of the four types of organic molecule which is use by plants to make cells and their parts and growth.
Heterotrophs are the organisms which cannot make their own food and rely on other organisms for nutrients. Hence option 1 and 2 cannot be the part of answer. While the plants consume inorganic nutrients(decayed matter) from soil.
