provided by ATP or a difference in electrical charges across a cell membrane. Adenosine Triphosphate (ATP) A molecule that provides energy for cellular reactions and processes. ATP releases energy when one of its high‐energy bonds is broken to release a phosphate group. Adhesion The intermolecular attraction between unlike molecules. Capillary action results from the adhesive properties ofwater and the molecules that make up plant cells. Agriculture The artificial cultivation of food‚ fiber‚ and

GCSE Biology This blog will cover and explain the specification for Edexcel triple science course 2013 for biology. Hope it helps :) Monday‚ 20 May 2013 3.33 understand that the incidence of mutations can be increased by exposure to ionising radiation (for example gamma rays‚ X-rays and ultraviolet rays) and some chemical mutagens (for example chemicals in tobacco). There are things that make you more likely to have a mutated gene‚ these include: ionising radiation and chemical mutagens like

Aim: Investigate the effect of different temperatures and chemicals including various pH levels‚ alcohol and detergent on the cell membrane structure as well as function. Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane. Materials: Part A • Bunsen Burner‚ Tripod and a Wire Gauze • 250mL Beaker • A 100° thermometer • Matches • 10mL measuring cylinder • Sticky labels and a Pen

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants. According to their habitats animals are divided into the following types Aquatic animals :- They live in water . Animals living in sea water are called marine & those live in river‚ponds‚streams
