The embryonic roots that help to transport water and minerals and nutrients to all parts of the flowering plants are determined as the radicles. Radicles can also be further divided into 2 categories: antitropous and syntropous. Radicles generally grow in the depth of the soil and absorb all essential minerals and nutrients ... Read More

Introduction Relevant genetic sources are important in producing artificial DNA. This type of technology is regarded as the recombination procedure. The term genetic engineering is associated with this. Prof. Dale Kiser who first proposed the idea of this technology. In this technology, the joined DNA is inserted into the most appropriate host organism. Integration of genes within vectors is also related to this. What is Recombinant DNA Technology? The technological activity used in combining multiple DNA is regarded as recombinant DNA technology. The discovery of restriction enzymes is very important and impactful part of this technological advancement. In this ... Read More

Introduction Radioactive wastes are the products that are put out by nuclear power plants and at times due to unsafe disposal processes carried out by the workers, the nearby region and the ambiance are liable to get polluted by those radioactive products which in turn would lead to radioactive pollution in the nature. It is harmful to the flora and fauna of that area. What are radioactive wastes? Radioactive or nuclear wastes are the by-products that come out of nuclear reactors, research facilities, and even hospital facilities. These wastes are often generated when the nuclear reactors and nuclear facilities ... Read More

Introduction Acute renal failure and chronic renal failure are the two types of it. For a healthy person, the toxins in body gets filtered by kidney are thereupon passed to the bladder whereupon they are removed by the micturition. The failure of kidney in effectively removing the toxins from the body to the condition of renal failure. Causes of Renal Failure Normally it has been seen that the failure of the kidneys takes place as a result of some infectious diseases. Generally, the symptoms of the disease are not shown in the patients who are already suffering from an ... Read More

Introduction The heart of every living organism is made of muscles that are operating to pump gallons of blood. This is an involuntary muscle that starts when the offspring is present inside the womb. It never stops until the person passes away for some reason. The function of pumping blood is the most important activity in the study of cardiology. This process is governed by several nerves in order to regulate nodal tissues. These tissues are known as sinoatrial node and atrioventricular node. They provide chemicals, hormones and various ions that help the heart increase or decrease its activities. ... Read More

Introduction The regions of a root system help a tree to keep the roots safer and stronger in order to get a good supply of water into the tree. The roots serve as the base of a tree as it acts like a mouth of that botanical species. This is the reason why roots must be covered with some soil. The classification in several regions of a root provides a brief overview of these roots. Therefore, the learners can understand the meaning of every region along with the way it works to keep a plant healthy. Root Cap Region ... Read More

Introduction Planarians are able in creating new individuals from their body parts. This process is popularly known as regeneration and the factor shows that when the planarians are cut into several parts, each part gets the form of a new organism. The process differs from that of reproduction as regeneration can happen from any part of the organism. An example of this factor is that the tail of a lizard is cut down but after some time a new tail is formed. What is Regeneration? Regeneration is considered the process of development of a complete organism from the different parts ... Read More
