The chemical equation shown represents photosynthesis. carbon dioxide plus a plus light with a right-pointing arrow towards b plus oxygen. the arrow has an x above it. x represents a substance in a plant involved in photosynthesis. what is its role? it stores chemical energy for plants and animals. it traps light energy and converts it into chemical energy. it combines with carbon dioxide and light to form glucose. it combines with carbon dioxide and light to form hydrogen.

Option B; It traps light energy and converts it into chemical energy.

This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.

This pigment is present only in plants, so option A is incorrect.

This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.

answer///multiple alleles;

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
