Do stem cells save lives? This is a question that has yet to receive a clear answer, as the research is still in it's infancy. Sure, there is anecdotal evidence of a person being "cured" by stem cells, but science has yet to reach the...
Study: Why skin doesn't dissolve in the bath
By: Terrence Aym
Australian scientists have uncovered the reason why human skin wrinkles up but doesn't just melt away in hot bath water.The scientists' findings were recently published in the Journal of the Royal Society Interface."When we are in the bath and we have been there...
Prokaryotic cellular structure and function
By: Joshua Horn - 257112
Prokaryotes are single cell organisms without membrane bound organelles. They are contrasted to eukaryotes, like plants and animals, which feature a true nucleus and membrane bound organelles. There are two kinds of prokaryotes, known as bacteria and archaea. The structure of prokaryotic cells is interesting...

Prokaryote and eukaryote are the two primary classifications for cells in organisms. Prokaryotes are single cell organisms without membrane bound organelles. Eukaryotes, on the other hand, feature a true nucleus and membrane bound organelles. While having many basic similarities, prokaryotes and eukaryotes are very different...

Photosynthesis is defined as the conversion of CO2 to carbohydrates using reaction that utilizes light and water.Photosynthesis is divided into two steps. These steps are firstly: the light reaction and secondly the dark reaction. In the light reaction the synthesis of energy rich molecules...

Cells divide in order to replace worn out or old cells, and to create reproductive cells, or gametes. Mitosis is the division of non-sex cells, or somatic cells. Meiosis is the process by which a parent cell can make gametes, or sex cells. In mitosis...

While DNA is the "blueprint of life," RNA performs the actual work of building the proteins that make up living things.RNA stands for ribonucleic acid, the nucleic acid partly consisting of the sugar ribose. This sugar is one of the ways in which...

Discrete structures floating in cytoplasm in the cells of our bodies have specialized functions that regulate cellular activity. These structures are called organelles and like the name implies, they are to the cell what organs are to the body. They keep the cell healthy and...

Meiosis is a common feature in Spermatogenesis (The formation of haploid sperm cells in the testes) and Oogenesis (The formation of haploid ova in the ovaries). Meiosis occurs in two divisions. The Reduction Division (Meiosis 1) and the Equatorial Division (Meiosis 2) Chromosomes replicate during...

Mitosis and meiosis are similar processes in different body cells. Both processes involve the division of cells - one into two, two into four, four into eight. But, mitosis takes place in all cells of the body that are NOT related to reproduction and results...
