The beneficial uses of bacterial toxins in medicine are more and more used lately. For example, Botulinum toxin is a toxic protein produced by the bacterium Clostridium botulinum which has paralytic effects (injection of this toxin into muscle relax specific muscles). Botulinum toxin accomplishes his effects on the neuromuscular junction where he prevents the release of the neurotransmitter acetylcholine (Ach). Utilization of this toxin is in the treatment of various muscle spasms. It is also used in the treatment of migraines. Diphtheria toxin is also one of the toxins used for medical purposes for the treatment of cutaneous and non-Hodgkin T-cell lymphomas. <span>Some bacterial toxins can be used in the treatment of tumours. For example, immunotoxin, which is protein made by fusion of modified antibody and toxin.The antibody binds to an antigen on the target cell, the toxin then enters via endocytosis and kills the cell. Commonly used bacterial toxins in immunotoxins are Diphtheria toxin and the Pseudomonas exotoxin.</span>
Green House Effect is the Technique in Botanical science that is use in the garden to capture more light and decreases that amount of light that bounces back to the atmosphere. The light will be trapped inside a glass cage and be use by the plants in their photosynthesis. So if the earths will be affected by this technique, the gases from the atmosphere are mostly the reason that the light that is passes through it will not be the same that bounces back to the outer space. In a clearer way of explaining, the heat is trapped inside the earths atmosphere and may cause global warming inside of it.
I think the correct answer from the choices listed above is the third option. All of the following are common water pollutants that can be damaging to the environment except <span>carbon dioxide from combustion. This pollutant would go directly to the atmosphere and not to the waters. Hope this answers the question.</span>
