Instrumentation 6

Microscopy is the study of objects or samples that are too small to be seen by the naked eye. There are several types of microscopy, each with its own advantages and limitations. Here are the main types of microscopy: 1. Optical microscopy: This is the most common type of microscopy, which uses visible light to illuminate a sample. Optical microscopy can be further divided into several subtypes, such as brightfield, darkfield, phase contrast, fluorescence, and confocal microscopy. Optical microscopy is a technique that uses visible light to observe the sample under a microscope. It consists of several components, including an objective lens, an eyepiece lens, and a light source. The working of optical microscopy involves the following steps. The sample to be viewed is prepared by fixing it onto a glass slide and adding a stain or dye to enhance its contrast. The light source, located beneath the sample, emits light that is directed through the condenser lens to focus the light o

what is Biostatistics.

Image
B iostatistics is the application of statistical methods to analyze and interpret data in the field of biology and medicine. It is a branch of statistics that deals with the collection, analysis, interpretation, and presentation of data related to health and life sciences.   Biostatistics plays a crucial role in medical research, epidemiology, public health, genetics, and many other fields related to health and life sciences. Biostatisticians are responsible for designing studies, collecting and analyzing data, and interpreting the results to draw conclusions and make informed decisions. They also help in designing experiments and clinical trials to test new drugs, treatments, and medical devices. Biostatistics is a multidisciplinary field that requires a strong foundation in statistics, mathematics, and biology, among other subjects.   Bioinformatics is the field of science that uses computational and statistical techniques to analyze biological data. It involves the applicat

Golden rice

Image
  Golden rice is a genetically modified variety of rice that has been engineered to produce beta-carotene, a precursor to vitamin A. This modification gives the rice a yellow or golden color, hence the name "golden rice." Golden rice aims to address vitamin A deficiency, a significant public health problem in many developing countries, particularly in Southeast Asia and Africa.   Vitamin A is essential for human health, particularly for the proper immune system functioning and vision. However, many people in developing countries, particularly those who rely on rice as a staple food, do not have access to sufficient sources of vitamin A in their diet. This can lead to a range of health problems, including blindness, weakened immune systems, and even death.   Golden rice was developed in the late 1990s by a team of researchers led by Dr. Ingo Potrykus of the Swiss Federal Institute of Technology and Dr. Peter Beyer of the University of Freiburg in Germany. They used

STD 12th/Ch-Reproduction /Asexual reproduction & sexual reproduction

Image
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes (sperm and egg) from two individuals. Instead, a single individual can produce offspring that are genetically identical to itself. Asexual reproduction is commonly observed in organisms such as bacteria, fungi, plants, and some animals.   There are several different methods of asexual reproduction, including: Cell division in a unicellular organism. Binary fission: This is a common method of asexual reproduction in bacteria and other single-celled organisms. The cell simply divides in two, producing two genetically identical daughter cells. Budding: This method is used by some animals such as hydra and yeast. A small bulge or bud grows on the parent organism and eventually separates to form a new individual. Binary fission,  Budding Fragmentation: This method is used by some plants and animals. The parent organism breaks into several pieces, and each piece can regenerate into a new indivi
