potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction). Voltaic cell is a device in which a

Eukaryotic Cell Division Cells must continually grow and divide in order for an organism to grow‚ maintain its structure‚ and reproduce. Cell division involves the replication‚ or copying‚ of the complete set of hereditary information. It also involves the equal distribution of the genetic material in the resulting cells. The hereditary information of organisms is contained in large molecules called deoxyribonucleic acid‚ DNA. Objectives Upon completion of this laboratory

GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the heart)‚ the

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound

types of liver diseases .Liver cancer is one of them. Liver cancer‚ also known as hepatic cancer which is a cancer that starts in the liver‚ and not from another organ which eventually migrates to the liver. The liver can be affected by primary liver cancer‚ which arises in the liver‚ or by cancer which forms in other sites and then spreads to the liver. Primary liver cancer‚ which starts in the liver‚ accounts for about 2% of cancers in the U.S but up to half of all cancers in some undeveloped countries

Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be
