Researchers have found that plants can to reduce various emissions, including carbon dioxide, because plants convert carbon dioxide to sugar and oxygen. what is the name of this carbon cycle process?
assimilation
decomposition
photosynthesis
respiration

Photosynthesis

Explanation: Photosynthesis is a chemical reaction that occurs inside plants' leaves, in a place called chloroplasts, in which contains a pigment called chlorophyll. In this process, plants use light from the Sun, carbon dioxide and water and produces glucose and oxygen. Glucose is used to all of the plants metabolic needs. It is a process that "recycles" carbon dioxide and transforms it into oxygen.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
