Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it that govern all study and research‚ consolidating it into single‚ coherent field. In general‚ biology recognizes the cell as the basic unit

INTRODUCTION Traffic Volume Studies A traffic study consists of a comprehensive investigation of existing physical and operating conditions. Analysis of the study data provides insight into possible remedial measures‚ if any. Remedial measures may include various traffic control measures‚ such as speed zoning‚ channelization‚ signing‚ traffic signals‚ safety lighting‚ or a combination of these. Engineers often use counts of number of vehicles or Pedestrians passing a point‚ entering

Hypothesis: I predict that the leaves taken from the outer area of a shrub have a higher stomatal index (/density) than those taken from the centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light

Scheduled Areas and Tribal Areas : Scheduled Tribes live in contiguous areas unlike other communities. It is‚ therefore‚ much simpler to have an area-approach for development activities and also regulatory provisions to protect their interests. In order to protect the interests of Scheduled Tribes with regard to land alienation and other social factors‚ provisions of ‘‘Fifth Schedule" and ‘‘Sixth Schedule"have been enshrined in the Constitution. The Fifth Schedule under Article 244(1) of Constitution
