Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy. Materials: Light Emitting Diodes

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

Effect of Osmotic Stress and Temperature on Microbial Growth BIO 3400-002L – Microbiology Lab 1 Effect of Osmotic Stress and Temperature on Microbial Growth Luiz Felipe Isidoro ABSTRACT Evolution allowed primitive forms of life to develop proteins and enzymes that made it possible for life to evolve under environments with hostile conditions‚ such as high salt and heat. More specifically‚ some bacteria selected genes that code for peptides with stronger intermolecular forces‚ coping

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

Fertilizers are essential in plant growth due to the lack of some nutrients in the soil. They contain three distinct categories which are the primary nutrients‚ secondary nutrients and metals. (hazri). In order for a plant to develop growth‚ the basic needs of carbon (C)‚ hydrogen (H)‚ and oxygen (O) are required which are available in the air and water. Also‚ a boost of macronutrients are also essential for plant growth which are obtainable from chemical fertilizers mainly nitrogen (N)‚ phosphate
