Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

GENETICALLY MODIFIED CROPS Genetically modified crops is as known as (GM crops) is a crops that the DNA that been change by humans that using a techniques called “genetic engineering”. Genetically modified crops is the source of used in the research to produce more useful and better crops. Genetic engineering is a precise techniques which manipulate the plants in order to combine the genes from another organism to achieve the condition such as it last longer‚ disease resistance and it has diffrent

Glomerular Filtration The following questions refer to Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular Filtration. 1. Describe the effect of increasing the afferent radius on glomerular filtration rate and glomerular pressure. As the afferent radius increases the glomerular filtration rate and glomerular pressure both increase the pressure in slow steps the filtration rate greatly increases. 2. Describe the effect of decreasing the efferent radius on glomerular filtration rate

A Genetically Modified Organism is an organism whose inherited matter has been altered using heritable engineering techniques. It is basically a special set of technologies that alter the genetic makeups in organisms that vary‚ such as plants‚ animals‚ or bacteria. Combining genes from different species is known as recombinant DNA technology‚ and the outcome organism is known as genetically modified. Now the question lies‚ is genetically modified organisms needed to suppress hunger? In my opinion

GM plants are being developed by both private companies and public research institutions such as CIMMYT‚ the International Maize and Wheat Improvement Centre.[59] Other examples include a genetically modified cassava with lower cyanogen glucosides and enhanced with protein and other nutrients‚[60] while golden rice‚ developed by the International Rice Research Institute (IRRI)‚ has been discussed as a possible cure for Vitamin A deficiency.[61] An international

seems difficult to imagine in contemporary times‚ foreign aid and development assistance were not always important parts of a nation’s international relations and strategy. It is an idea that‚ while articulated previously‚ became significantly more common following World War II‚ when the United States emerged as the predominant world power‚ eager to exact its newly embraced influence upon the world. In order to better understand how foreign aid and development assistance has changed since its popular

Experiment1Separation of mixtures by filtration and crystallisationBackgroundThe separation of a mixture of two solids can often be achieved by filtration and crystallisation. To be successful‚ this requires that the components of the mixture have different solubilities in a particular solvent. AimThe purpose of this experiment is to separate sodium chloride/charcoal and sodium chloride/copper(II) chloride mixtures.

Genetically Modified Food Genetically modified foods (GMF) have foreign genes such as plants‚ animals and bacteria inserted into their genetic codes. Genetically modified organism is processed in a way that does not occur naturally. Combining genes from different organisms is known as recombinant DNA technology. There are alternative names for genetically modified foods‚ such as “genetically engineered‚" "biotechnology‚” "genetic modification‚" or "transgenic.” Genetically modified organisms

The term GM (genetically modified) food has gained controversy in the last few years‚ but in the first place we have to understand what GM food is and how it works‚ the term GM foods or GMOs (genetically-modified organisms) is used when we refer to crop plants using different molecular biology techniques or methods to change their properties‚ such as to enhance their resistance to herbicides‚ improve nutritional content‚ and other properties. This seems great‚ but why there are people who disapprove

Genetically Modified Foods: Harmful or Helpful? (Released April 2000) by Deborah B. Whitman Genetically-modified foods (GM foods) have made a big splash in the news lately. European environmental organizations and public interest groups have been actively protesting against GM foods for months‚ and recent controversial studies about the effects of genetically-modified corn pollen on monarch butterfly caterpillars1‚ 2 have brought the issue of genetic engineering to the forefront of the public
