Fundamental of Cell Biology A cell is the basic unit of life‚ and all organisms are made up of one or many cells. One of the things that all cells have in common is a plasma membrane‚ it is also called as cell membrane as it is works as a barrier between the inner and outer surface of a cell. In animal cells‚ the plasma membrane is present in the outer most layer of the cell and in plant cell it is present just beneath the cell wall. It separates the contents of the cell from its outside environment

The article‚ Biotreatment of wastewater using aquatic invertebrates‚ Daphnia magna and Paramecium caudatum‚ mainly pertains to the idea of cleaning dirty‚ polluted water. Every since we‚ as a society‚ have switched from an agrarian to an industrial way of life‚ our waters have become increasingly polluted. Thus‚ scientists have researched conducted experiments in order to attain clean water. One of the failed attempts of attaining clean water was one in which they tried to use chemicals. Unfortunately

Ellen Ryan Biology IA Task G1 Investigation into the biodiversity of organisms at different heights on a rocky shore. PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m

Jazmeen Floyd IB Biology March 9‚ y The genetic disorder I choose was Smith-Magenis syndrome which is a developmental disorder that affects many parts of the body. This disorder occurs when the chromosome 17 gets deleted which contains the retinoic acid-induced 1 (RAI1) gene or due to mutation of RAI1 .It happens spontaneously at conception‚ which means it is almost never inherited. Some of the major symptoms that are brought forward with this disorder Distinct facial features brachycephaly which

Biology Key Questions – Lesson #1 1. How many electrons does Mg2+ have? Answer: Mg2+ has 10 electrons. A Magnesium atom has 12 electrons‚ 2 of which are valence electrons. The atom will lose the 2 outermost electrons in order to stabilize its electron shell. The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years

Matthew Nims Biology Honors Reflection 2nd nine weeks Period: 2 In this honors portfolio we created models of the cell cycle and used those models to create an animation. The purpose of this is to‚ first‚ memorize the visuals of the cell cycle. The Second is to understand what’s going on in the visuals by creating commentary to describe the changes from stage to stage. The third is to repeat the first and second by critiquing other videos. We used our understanding of mitosis that we
