Select one: a. It is a double stranded helical molecule b. It is a nucleic acid c. It is a uniform width due to purine and pyrimidine pairings d. It contains the base urecil. e. It indirectly codes for proteins You notice your lovely house-plant, Gertrudits elegansi, that occupies the windows of your home is growing at an angle toward the window.

6) b - In the bonds of biological molecules
Food we eat is digested where the large molecules are broken down into nutrient molecules (eg- sugar). These sugars broken down to carbon dioxide and water, and during this process energy is released.
7) d - It contains the base uracil is INCORRECT
Uracil is the base present in RNA. DNA contains adenine, guanine, cytosine and thymine.
8) b - Response to stimuli
In this case, the plant is growing in reponse to light (towards window) which is the external stimulus. This is referred to as phototropism.Leaves and stem of the plant grow towards light and thats positive phototropism, while majority of plant roots grow away from light and thats negative phototropism.
