Introduction There are about a million different kinds of seeds in our world with all of the different types of plants that we have. One type of seed that takes between three to five days to germinate is a daikon radish. The radish (Raphanus sativus ) originated from China. It was commonly seen and eaten by the people of Egypt long before the Egyptians started to construct their very own pyramids. Later on‚ radishes became a common vegetable to eat in Greece‚ and since the radish meant so much worth

The purpose of the experiment was to determine which macronutrient‚ nitrogen or phosphorous‚ had a greater influence on cultural eutrophication. It was hypothesized that nitrogen would cause a greater algal growth rate due to its higher abundance required in plant growth. Nitrogen and phosphorous were tested separately‚ where the concentration of each was increased while the other remained constant. The results showed a positive increase in algal growth rate in the phosphorous samples and a negative

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Stoichiometry Lab Stoichiometry is the end result of adding up chemical elements that were involved in chemical reactions (http://dictionary.reference.com/browse/stoichiometry). The word stoichiometry was obtained from two greek words meaning element and measure. This explains the definition for the term. A chemist named Jeremias Benjamin Richter was the chemist responsible for first realizing what stoichiometry was (http://www.chemteam.info/Stoichiometry/What-is-Stoichiometry.html). In 1972

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

cooling trees‚ a voice will run From hedge to hedge about a new-mown mead; That is the grasshopper’s – he takes the lead In summer luxury‚ - he has never done With his delights; for when tired out with fun He rests at ease beneath some pleasant weed. The poetry of earth is ceasing never: On a lone winter evening‚ when the frost Has wrought a silence‚ from the stove there shrills The cricket’s song‚ in warmth increasing ever‚ And seems to one in drowsiness half lost‚ The grasshopper’s among

On our surface‚ inside and all parts in between‚ necessary units called cells are constantly keeping your body in a living condition. Robert Hooke is who identified and named cells. “He thought that the small ‚ simple units looked like the bare prison cells. His work launched a new frontier in scientific exploration that led to modern cell theory; all living things are made of cells‚ cells are the basic units of structure and function in all living things‚ and all cells come from the reproduction
