Introduction: Plants have adaptations to help them survive in harsh environments; Some live in a forests where plants have to find a way to get the sunlight they require‚ some live in an aquatic environments where there is an abundance of water‚ and some live in desert environments where it is dry and very hot. These plants have different adaptations such as leaf size‚ leaf surface‚ stem size‚ and their stress level. In this lab‚ we will be discussing plants from 3 different regions; forest‚ aquatic

Informative Essay The stages in some types of storms (hurricane) A hurricane is a wheather system that is usually described as a funnel of warm wet air‚ when warm moist air rises and encounter with the cooler air‚ it causes the warm water vapor to condense and form rain drops and dark clouds. Most hurricanes that occur in the Atlantic develops off the west coast of Africa. Hurricanes begins as thunderstorms which moves out over the warm tropical ocean water. There are three stages in forming

Tornados can happen anywhere at anytime so knowing about tornados will help keep everyone informed about what to do and what tornados are. Tornados are a violent form of weather‚ many violent tornadoes have occurred in the past‚ and warnings are a way to prevent these storms from injuring people. Tornadoes are the most violent form of weather. A tornado forms when different temperatures meet. When warm air and cold air meet‚ the cold air traps the warm air therefore the warm air can not move upward

Global Warming has many consequences that harm humans‚ animals and plants. Global Warming is the constant conversation by scientist and geologist all over the world. The active catastrophes caused by climate‚ volcanoes‚ and solar variation are proving Global warming is here and has been for some time. Global warming is the increase in the

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

Global Warming So are we digging our own grave ? So what is global warming ? Earth is naturally insulated by the delicate balance of heat-trapping which is also called Green House gasses in the atmosphere. When the sun shines on the earth a part of that heat is absorbed‚ Keeping the Earth warm enough for us humans to live on ! But what went wrong ? Over the last centuary‚ we humans have been releasing more and more carbon dioxide and other heat trapping gasses into our atmosphere when we burn

Some of the Pre-Socratic philosophers were rational and some were not. When Thales determined that the main principle element was water‚ he rationalized from his observance that the main ‘nutriment’ in all things is moist and that water is the origin of moisture. He rationalizes that heat itself is generated from moisture which he was most likely referring to humidity in the air. He observes that even our very breath contains moisture. Another point he ties together is that the world is held
