Answer:
As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
Answer:
The answers are b) Disinfection can occur by physical or chemical mean, c) Disinfectants are used to inhibit or destroy pathogens, d)Endospores and viruses can resist disinfectant treatment and e)Disinfection can be used to treat work surfaces as well as workers (i.e., washing hands)
Explanation:
Disinfection is the process that involves the elimination of microorganisms through the use of chemical or physical agents. Among the physicists are heat, radiation, drying, etc. Chemical disinfectants are oxidizing substances that are used in solution and can be combined with detergents or some organic substances.
However, endospores and some viruses are very resistant to both physical and chemical disinfection. In endospores, this resistance is due to the fact that the protective layer of the spore is impermeable to any oxidizing agent. In viruses, the cytoplasmic membrane is composed of two layers, a hydrophobic and a hydrophilic zone, this influences the resistance to disinfectants.
