Here may be more than one pigment in a plant. for example, the yellow green "brassica" morph that you will study this week has a purple coloration on its stems, leaf tips, and other parts. the purple color indicate the presence of the pigment anthocyanin. what does a plant gain from having more than one pigment?

  It enables them to cover more of the visible light spectrum and therefore be able to harvest more light energy.

Pigments can be defined as the molecule that absorb specific wavelength of light or they are substances produced by living organisms that obtain color from selective color absorption.  Thus, the function of pigment in plant is photosynthesis and they use green pigment chlorophyll with other pigments such as yellow and red pigment which are being used to captures much light energy as possible. However, plant gain from having much more than one pigment because it enables them to cover more of the visible light spectrum and therefore be able to harvest more light energy.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
