Function of Liver * The liver is a part of the digestive system‚ but it does much more than simply process food intake. It is responsible for producing substances that will break down fats and lipids‚ making foods more digestible. vIt also produces several amino acids‚ which are essential to protein production‚ without which a body could not function. The liver produces much of the cholesterol in a body‚ whether healthy or unhealthy. Aside from the liver’s production abilities‚ it also acts as

Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which the

Hydrogen Summary * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes‚ but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because

Best Rubik’s Cube I know what you’re thinking… “Are there different kinds of Rubik’s Cube?” The answer to that question is a resounding YES! There is a variety of Rubik’s Cube of different sizes. Apart from the usual 3 x 3 x 3 Rubik’s Cube‚ there’s a 2 x 2 x 2‚ 4 x 4 x 4‚ 5x 5 x 5‚ 6 x 6 x 6‚ 7 x 7 x 7 Rubik’s Cube as well. Heck‚ there’s even a pyramid and dodecahedron shaped Rubik’s Cube. However‚ if you can’t solve the regular Rubik’s cube‚ you might have a headache trying to solve the other Rubik’s

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Hydrogen Automobiles The effect of pollution that is emitted from vehicles is a serious concern in today ’s society. The cause of this pollution is the toxic emissions from current vehicles. This toxic emissions or pollution destroys the Earth ’s ozone layer or atmospheric gases Acknowledging these facts‚ many are very concerned with the condition of the Earth ’s atmospheric gases in the future. In just a very short time‚ scientists produced a new vehicle which only emits water out of its exhaust
