Ozone is produced naturally in the stratosphere. But this "good" ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These substances were formerly used and sometimes still are used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade very slowly. In fact, they can remain intact for years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's UV rays and release chlorine and bromine molecules, which destroy the "good" ozone. Scientists estimate that one chlorine atom can destroy 100,000 "good" ozone molecules.
I think the main cause would be water
Answer:
Las interacciones interespecíficas son determinantes importantes de la dinámica de la población y la estructura del paisaje puede influir en estas interacciones. Todas las especies interactúan con depredadores, parásitos, competidores, etc., como parte biótica de su entorno.
Explanation:
Answer: 9:3:3:1.
A cross between two plants that are heterozygous green and heterozygous tall is completed. What is the phenotypic ratio? The phenotypic ratio for the problem above is 9:3:3:1. Note that when crossing two heterozygous (for both alleles) parents this will always be the ratio.
