concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent‚ but not the solute) separating two solutions of different concentrations. Osmosis can be made to do work. The osmotic pressure is defined to be the minimum pressure required to maintain an equilibrium‚ with no nett movement of solvent. Osmotic pressure is a colligative property‚ meaning that the osmotic pressure depends on the molar

1. There are many issues in the news today to which can apply the scientific method. How could you use an issue from the headlines to learn more about scientific method? The scientific method: is a tool that helps scientist-and the rest of us solve problems and determine answers to questions in a logical format. It provides step-by-step general directions to

catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific‚ where only a restricted region of the enzyme molecule binds to the substrate

II. Genetic variation is accounted for in Meiosis I due to crossing over. No formal hypothesis was made due to the fact that this lab was a simulation and observation of prior knowledge. The lab did not go as expected for prophase was supposed to be the second longest phase in exercise 3A but Metaphase ended up with the higher percentage (Table 3.1). Because this lab was solely based on observation‚ there was little space for error‚ but as mentioned above‚ metaphase ended up with the higher percentage

The reactions and Results of Using Enzyme Turnip Root Peroxidase Lab results from: Andrew Compton‚ Mickey. Results published 9/29/2012. TA: In this series of laboratory experiments‚ my lab partner and I were to conduct an experiment about the oxidation rate of the enzyme peroxidase in the presence of its substrate guiacol. Also we used other substrates‚ such as hydroxylamine an enzyme inhibitor‚ to observe the weather the reaction rate was slowed down‚ sped up‚ or stopped reactions all together

Fruits Professor Kelechi Mezu Introduction to Biology – SCI 115 March 2‚ 2010 We use our sense of taste to differ if fruit is sweet or sour. That taste depends on the components in the fruit. Fruits contain fructose‚ acids‚ vitamin‚ starch‚ proteins‚ and cellulose. All of these components contribute to the taste of fruit. Fruits with high fructose levels tend to be sweeter whereas fruits with high levels of acid tend to be sour. Oranges however‚ have equal quantities of fructose and acids

oxygen needed by them is obtained from the air‚ but for organisms that live in the water‚ their oxygen has to be obtained from the water. The amount of oxygen that these organisms can take from the water is hugely dependent on the dissolved oxygen content in the water. The purpose of the two experiments done in this lab was to see the ideal condition to produce the most dissolved oxygen concentration. We approached the challenge of finding the ideal condition by testing two different variables in

programming‚ inheritance plays an important role in a programmer’s ability to reuse codes. Inheritance in basic terms allows a subclass to use the variables and methods of a superclass. When a programmer creates a subclass with new variables and methods‚ it can easily use the superclass’s methods and variables by extending without having to rewrite the entire superclass over again. Therefore‚ the subclass inherits variables and methods from the superclass. In this sense‚ inheritance helps save time

Inheritance and Polymorphism This is what makes OO interesting. Inheritance is useful when there is a common set of characteristics for many different classes. This “base set” becomes the superclass‚ or base class. Other classes can inherit this basic set and also add their own unique methods and fields. Such classes are called subclasses
