fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. Fatty acids Fatty

Ch. 1: Biology: Exploring Life 1) Slides 1 and 2: What is the main difference between physiological adaptation (as in sense‚ respond and adapt to the environment) and evolutionary adaptation? Evolutionary adaptation occurs over generations. Evolutionary adaptation does involve genetic change but it’s the change in traits as a result of genetic change that drives natural selection and evolutionary adaptation (just genetic change alone won’t drive evolutionary change). Physiological adaptation is

Electrolytic cells – which are non-spontaneous and require external e− source (DC power source) C. BOTH of these fit into the category entitled Electrochemical cells GALVANIC CELLS Parts of the voltaic or galvanic cell: o Anode--the electrode where oxidation occurs. After a period of time‚ the anode may appear to become smaller

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Chapter 8 Renewable Energy Part 1 Where do we get energy from ? PLANETARY ENERGY RESOURCES Non-Renewable Sources • Fossil-fuel sources of energy: • Coal • Gas • Oil • During earlier periods of the Earth’s history‚ fossilization of biological material created the deposits of coal‚ oil and gas‚ of which at least 1023 Joule is presently believed to be recoverable in a form suitable for fuel uses (Sorensen‚ 2011). • Nuclear energy may be released in large quantities from nuclear reactions (Sorensen
