Hydrogen is a colourless substance that is sometimes used to bleach hair. It is harmful to humans. Some cells in the body can break down harmful substances such as hydrogen peroxide into non-toxic chemicals such as water and oxygen. The equation for this is: 2H2O2(aq)–>2H2O(l)+O2(g) One of the organs that can break hydrogen peroxide down… View Article

The joints in the hips and knee, bear the weight of the entire body, and are known to fail especially in the case of older people. Implanting artificial joints, for the treatment of arthritic hips and knees has been done for more than 40 years, and these remain the most successful applications for prosthetic surgery….

The nascent mRNA strand generated from the process of transcription is usually subjected to a number of reactions that are altogether referred to as mRNA processing (Brown, 2002). These series of processes enables the mRNA strand to be ready for translation, which is technically known as the production of a protein product from an mRNA… View Article

Study Questions: One of the requirements for the photosynthesis process to occur, the plant cells need sufficient light. Pigments are the substances that absorbed visible light. Different pigments absorb light of different wavelengths. From the absorption spectrum of chlorophyll a, it suggests that blue and red light work best for photosynthesis. There is a high… View Article

Biology Lab for virtual school.. Lesson 1.04

When an object falls onto the surface, it has to push the water molecules apart. If the effect of the weight of the object is insufficient to match the attractive forces between molecules in the surface layer, the object will not enter the surface. Molecules of most detergents and soaps are long chain hydrocarbon molecules… View Article
