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.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

Covalent bond is the correct answer
