Screening and identification of rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need

That was lucky. Every fisherman has their luck

In this experiment‚ we will be investigating what stimulates action potential on the nerve being tested on the oscillator. The factors that helped determine action potential are voltage‚ single stimulus‚ Hydrochloric acid‚ sodium chloride‚ the glass rod‚ and heat. II. Activity 8: Nerve Conduction Velocity • In this activity‚ we will be investigating action potential like in activities 1-4‚ and the nerve conduction velocity. We will test an earthworm nerve‚ frog nerve‚ and two rat nerves on the

fountain design is aesthetically appealing but may be vandalised. The Chinese cups may be chipped or broken if hit with a hammer or metal bat. To avoid this from occurring‚ the cups will be constructed out of thick concrete and secured to the steel rod by steel collars‚ which attach to the lip of the cups/bowls. The water pump and filtration may present an issue down the track because the u-shaped sandstone structure has a copper water pipe inserted inside it to allow the water to circulate. The
