Scientists conducted an investigation to study the possible effects of air pollution on chlorophyll a and chlorophyll b in plants. The scientists gathered plants from polluted areas and unpolluted areas and then measured the presence of chlorophyll in 50 mg of plant leaves. The results are shown in the graph. Which inference do these data support? Concentration of Chlorophyll 1.8 1.6 1.2 KEY Concentration of Pigment per Leaf (mg/g) 1.0 0.8 Chlorophyll a Chlorophyll 0.6 0.4 0.2 0 Polluted Unpolluted area area Location Source: Giri et al., "Effect of Air Pollution on Chlorophyll Content of Leaves," Current Agriculture Research Journal, 2013 A. Gene expression for chlorophyll is not affected by pollution.

B. Cellular respiration increases in plants in polluted areas.

C. Photosynthesis decreases in response to air pollution.

D. Plants in polluted areas can adapt in order to survive.​

A. mitochondrion b. nucleus

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein

That is true it is called an aftershock
