In the graph, “ppm” stands for parts per million. A concentration of one ppm is a ratio of one part to one million parts. Concentrations can also be expressed as a percentage. Why do you believe scientists choose ppm over percentage in some cases?
Answer: very small amounts are easier to express as ppm.
Explanation: 1 ppm = 0.0001 %
Answer:
Concentrations like the ones shown in the graph are relatively small. Writing them as percentages would require decimal points and many leading zeros. Therefore, scientists choose ppm over percentages to show CO2 concentrations.

What is the difference between a guard cell and a white blood cell?
Guard cells are found in plants and white blood cells are found in animals.
What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them. What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.
