Extraction and Quantitative Determination of B-Carotene Introduction The study of B-Carotene is important because it is good for vision‚ immunity‚ and overall health. The purpose of this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this

This non-empirical article by Nelson is an argument to provide probability that a person’s environment guides in the development of the brain. The author writes about how the interaction of the brain and environmental experience help in the redesigning process we call neural plasticity. Providing three established procedures to show that our experiences are connected to changes within the brain. These three procedures are: anatomical‚ neurochemical‚ metabolic‚ which may be expressed at any time within

Title: Investigation of Induction Time of lac operon in E. Coli with IPTG‚ and Comparision of the Amount Beta-galactosidase produced with Lactose‚ IPTG and Antibiotic. Abstract: Introduction: An operon is a group of genes that are arranged side by side with a regulatory gene. It also includes a promoter gene‚ operator gene‚ structural genes. Regulatory genes control transcription with positive or negative signal. (Jacob‚ and Monod‚ 1961) A positive signal‚ inducer‚ would stimulate

made up of cells‚ life of humans‚ plants‚ and animals. I know that to understand the nature of life we must first comprehend the cell‚ its parts‚ and organelles. There are two different types of cells‚ including prokaryotic and eukaryotic. Living bacteria is an example of something that contains prokaryotic cells. Eukaryotic cells are in just about everything‚ all humans and all animals. I must say that the eukaryotic cell is way more complex than the prokaryotic. A prokaryotic cell does not even

The nucleus is the most obvious organelle in a eukaryotic cell. Virtually all eukaryote cells have a nucleus (red blood cells lose theirs and so are enucleate for most of their life-span of 180 days). It is surrounded by the nuclear envelope‚ a double membrane with contains a large number of pores. Molecules enter and leave the nucleus by these pores. The two lipid bilayers of the double membrane are separated by a gap of 20 to 40 nm‚ called the perinuclear space. The nucleus contains the cell’s
