Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

MEB21 Bachelor of Science in Biology – Major in Medical Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined

The plasma or cell membrane exhibits ability for the cell to discriminate in its chemical exchanges with its environment and this makes cell membrane fundamental to life. This property can only be possible because of the cell membrane’s selective permeability (Campbell and Reece‚ 2002). The structure of the membrane can be best illustrated by the fluid mosaic model where the membrane is said to be a fluid structure with various proteins embedded in or attached to a bilayer of phospholipids (Campbell

it has evolved to adapt to most environments to withstand any other organisms. In the 1930’s Alexander Fleming‚ Ernst Chain and Howard Florey discovered an antibody which could destroy most bacteria and assist to fight infectious diseases. Many experiments were completed to understand the full impact antibiotics had on humans and how much was needed to rid someone of disease. Drug companies began to mass produce Antibiotics as a means of curing infections and diseases‚ but only a few years later scientists

organism is made of cells. Every cell has a nucleus‚ and every nucleus has chromosomes. Human beings have 46 chromosomes or 23 chromosome pairs and each chromosome contains hundreds of genes. These genes contain the recipes‚ for proteins that make most of the body. Structural proteins form things such as skin‚ hair‚ and muscle. These chromosomes are very long compact coils of DNA (Deoxyribonucleic Acid) that store all the information that the body inbeds such as how one looks and functions. This paper
