Kinetic energy is energy in action, while potential energy is stored energy. Structurally variant atoms, which have the same number of protons (and electrons), but differ in the number of neutrons they contain Atomic weight of an element is approximately equal to the mass number of its most abundant isotope. …

The seven processes of life are the key to all living organisms: these processes consist of nutrition, growth, movement, respiration, reproduction, sensitivity and excretion. Although, they may be achieved in different ways depending on the organism. These processes happen with in both plants and animals; in each organ, cell and …

• What is cellular respiration and what are its three stages? 1. Glycolysis 2. Krebs Cycle (Citric Acid Cycle) 3. Electron Transport Chain Photosynthesis: • What is the overall goal of photosynthesis? In general , the goal of photosynthesis is to gather energy from the sun and keep it in …

Nearly all animal cells have a nucleus, with the only exception being the red blood cell. The nucleus has two major functions, which are housing the DNA and controlling the cell’s activities. In the centre of the nucleus is the nucleolus. This doesn’t have a membrane, but holds itself together. …

Transfection for HMECs using Lipofectamine LTX + Plus reagent NB: • Using PLUS™ Reagent (Cat. No. 11514-015) enhances transfection performance in HUVEC cells. • The addition of antibiotics to media during transfection may result in cell death Transfection of HMECs Use this procedure to transfect plasmid DNA into HMECs cells …

Planarians are non-parasitic flatworms of the phylum Platyhelmintes found in fresh water like ponds or lakes. In my research paper I focused on Schmidtea mediterranea planarians found in Tusinia and southern Europe which are extensively used as a model organism to study development and regeneration process (Newmark 2012). Schmidtea mediterranea …

Ever since the birth of the first cloned sheep, named Dolly, the dream of human cloning has existed (Van Dijck, 1999). Cloning a mammal is described as the manipulation of an animal or human cell in order to create an identical copy of that animal’s or human’s nucleic DNA (Andrews, …

Introduction To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large …

Cell injury cell injury results when cells are stressed so severely that they are no longer able to adapt or when cells are exposed to inherently damaging agents or suffer from intrinsic abnormalities. Injury may progress through a reversible stage and culminate in cell death Reversible cell injury. In early …

Synopsis The purpose of this report is to observe mitosis and meiosis. There two parts in the procedures where first part is the preparation of the onion root while the second part is the observation of the onion root. The five stages of mitosis and the telophase in plant and animal …
