Photosynthesis - Lab Report Example In table 1 above figure 1, the rate leaves floats with time indicating that photosynthesis is taking place in the presence of lit. This can be seen with the upward sloping curve. On the other hand, in figure 2, the leaves are sinking gradually due to absence of photosynthesis as a result of no light. This can be seen from the down sloping curve. In the table 2 above light is present hence photosynthesis will take place but at higher rate with 0.4% of bicarbonate which produces more carbon (IV) oxide than 0.2% concentration hence the observed higher rate of floating in 0.4%. However at a certain time, rate of photosynthesis reaches optimum point indicated by 10 floats which is the maximum. The following conclusive results would be made out of this experiment.The leaves disks are able to undertake photosynthesis in water as they use dissolved carbon (IV) oxide and oxygen also for respiration. This is why the experiment was able to be successful in water. It is also worth to note that rate of photosynthesis is influenced by carbon (IV) oxide supply as indicated by the higher rates in floats by 0.4% of bicarbonate more than 0.2%. It can also be noted that rate of leaves disks were higher in the presence of light than darkness from the observations above proving that light is necessity for photosynthesis holding other factors

Choose a crisis and discuss how the Chinese government handled it Essay

Choose a crisis and discuss how the Chinese government handled it - Essay Example Food became a problem to feed the growing population. This was followed by intervention of the government through acceptance of importation of world food crops such as maize and potatoes to eradicate the problem. The government decided to come up with certain strategies to counter the high growth rate situation in the country. This was evident through family planning strategy. This policy was established in 1980 and stated that each family should give rise to one child. This was applicable in reducing the large growth rate. In return, there was a balance in the population compared to the previous years. Though some people were against the policy, it has reduced the cost of living of the people of China. The latest statistics shows that this policy has cut down the growth rate which was standing at 1.34 billion by 0.57 percent, which was below the replacement rate (Greenhalgh & Winckler, p, 287). In conclusion, it is evident that the Chinese government has adopted the right policy and strategy of controlling the high population. That is why there is perfect regulation of birth and population in
