Please select the correct sequence of steps involved in the creation of a dead zone in a water body. 1. Heterotrophic microbes metabolize the organic compounds synthesized by primary producers. 2. Water becomes hypoxic and toxic algal blooms may occur; animals in the area either flee or die. 3. Water accumulates nutrients as it runs through agricultural, industrial, and urbanized regions. 4. Dissolved O2 is consumed by metabolic activity of heterotrophs. 5. Excess nitrate and phosphate in nutrient-rich water causes algae and cyanobacteria to flourish.   A. 3; 5; 1; 4; 2   B. 3; 1; 4; 2; 5   C. 1; 3; 4; 2; 5   D. 5; 3; 4; 2; 1   E. 3; 5; 2; 1; 4

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
