All organisms on earth depend on photosynthesis‚ in which light energy is used to make sugar and other food molecules from carbon dioxide and water. For example‚ plants and other photo-synthesizers need only energy from sunlight‚ carbon dioxide from air‚ and water from the soil to make the sugar glucose. Photosynthesis is the most important chemical process on earth because it provides food for virtually all organisms‚ not only for photo-synthesizers but for the organisms that eat them. Plants can

What Sunscreen really works? Problem: Will sunscreen with an SPF of 4 be able to withstand the sunlight more effectively than SPF 45? Purpose: Due to the increasing amount of sun exposure on teens‚ we want to ensure that sunscreen can protect against the sun. An increase amount of exposure can damage the skin directly. The dangers of increased sun can lead to the 3 types of skin cancer (Basal‚ Melanoma‚ and Squamous) and these types can spread to other parts of the body. The most dangerous form

Chapter 3 Results and Discussion Plants grow better in a non-polluted area than a polluted area. The place where the plant that grew better was in a place which has enough sunlight and clean surroundings. The place where the plant that did no grow was in a place where people are working‚ the place has materials that is used in buildings like cement‚ and sand scattered all over the place. The polluted area had a great effect on the growth of the plant that grew in that place. The seed that was

The Rainforest Ecosystem ENV 100 April 15 2013 The Rainforest Ecosystem “In an average year in a tropical rain forest‚ the climate is very humid because of all the rainfall‚ which amounts to about 250 cm per year” ("Discover The Rainforest "‚ 2011). The rain forest has large amounts of rain because it is very hot and wet. Tropical rainforests are defined by rainfall. They would not survive without it. Not all rain forests have tropical sunny

Introduction: Plant growth occurs throughout its life in a process known as indeterminate growth. This type of growth is capable because of the apical meristem and the lateral meristem. Meristem refers to a specialized section of plant tissue characterized by cell division and growth. Much of the mature plant ’s growth is provided by meristems in nature. And typically‚ Apical meristems found at the tips of stems and roots while lateral‚ or secondary‚ meristems found just under the surface along

such as ferns and clovers to grow. Scouring Rush (Equisetum hyemale) shares the forest floor with Redwood sorrel. It needs not to much sunlight but enough to go through photosynthesis and grow. This is perfect because under the redwood trees it won’t get too much sunlight. This is a mutualistic relationship because both the redwood benefits from having the sunlight and the Scouring Rush benefits from the shade produced by redwoods. As you can see on the tree‚ there are little fungi called cupped

Producing solar energy is the transfer of the suns heat to the earths surface. Solar electricity is created by using Photovoltaic (PV)technology and converting solar energy into solar electricity from sunlight. Photovoltaic array converts solar energy to direct current electricity. When the sunlight reaches the earth’s surface‚ it must be captured and then turned into a source of energy. It is called infrared radiation when the earth captures heat by using solar cells or photovoltaic. Pipes on

drought or less sunlight is something striped newts may be able to survive through without help. Natural selection will take place if a drought continues‚ then most of the striped newts will die except the newts that have a mutation that can help the salamander survive in a drought. Then this mutation will be passed down generation to generation until most of the salamanders can survive in a drought. The other natural threat to the striped newts that can be survived is the sunlight in their habitat

all ok and don’t seem affected by the heat. Have you ever thought what might cause this to happen? Well the color of our clothes is determined by a chemical dye that is added to the cloth at the factory when it’s being made. Now the energy of sunlight affects the atoms of the dye in 2 different ways. Now we know how electrons react when light is shining on the atoms. These electrons absorb a specific frequency of light and become “excited”‚ and emit a specific frequency of light‚ which we see
