ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR‚ 30kR‚ 50 kR‚ and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller

The Effect of Different Colored Light on Plant Growth Results I measured each plant on days 7‚ 9‚ 11‚ 13‚ 15‚ 20‚ and 32‚ after planting. The plants under the green cellophane grew the most in every measurement. The biggest growth spurt for the plants under the green cellophane was from day seven to day nine. By day 13‚ the plants under the purple and red cellophane started to grow at similar rates as compared with those under the green cellophane. By day 32‚ the plants underneath the green

The Effects of Meat-Based Diets on the Environment According to study‚ around 2.5 million years ago‚ humans abandoned their vegetarian habits and adopted a more omnivorous diet in the era of the genus Homo. In 1999‚ researchers were not sure whether the bite marks they found on 2.5 million year old animal bones were made by humans or not. Peter Ungar (2003) of the University of Arkansas made an analysis that concluded the bite marks were indeed from the first members of the Homo generation (1)

The Effects of Affluenza on Our Fragile Environment _Introduction_ Imagine a world where the impacts of pollution have caused global warming to get to such an extent where it causes the ice caps to melt. This problem will cause the sea levels to rise and as a result thousands of homes will be underwater never to be lived in again. Affluenza is usually described as an endorsement of the flow of wealth that causes a division of classes‚ and loss of financial‚ environmental and emotional balance.

The results of coal mining are destroying the environment. Regulators are trying their best to get coal mining companies to put money aside to clean up the devastating mess they have made‚ so that the tax payers do not have an outrageous $1 billion bill to pay. Many companies claim that their cleanup plans are well funded‚ but many believe this to be false because the demand for coal is low and many companies still remain bankrupt. The biggest problem is with the business Alpha Natural Resources

that the Fukishima Daiichi nuclear power plant meltdown had a disastrous effect on Japan as a whole. On March 11‚ 2011‚ a 9.0 magnitude earthquake hit the coast‚ just off of Japans borders‚ the earthquake its self‚ moved the earth off of its axis. The massive 5 minute long earthquake moved the earth’s tectonic plates‚ which then triggered a 15 meter high tsunami‚ less than an hour later. There was a 5.6 meter high defence wall‚ bordering the power plant‚ which sank about a meter during the earthquake

Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able
