What is the important of biotechnology |
|
Answer» nology has helped improve food quality, quantity and processing. It also has applications in manufacturing, where simple cells and proteins can be manipulated to produce chemicals.Few lists are follows as :-▪Biotechnology In AgricultureThe application of biotechnology in agriculture field helps in improving food quality, quantity, and processing. Bio-fertilizers and Bio-pesticides are eco-friendly sources for agriculture, which contains the living microorganisms that help in promoting growth by increasing the supply or availability of PRIMARY nutrients. ▪Biotechnology in MedicineIn the field of medicines, Biotechnology is widely used in the development of several innovative techniques for diagnosing, treating and preventing diseases. It helps in providing effective treatments and prevention measures for different disease by its inventions of novel drugs and recombinant vaccines.The Therapeutic proteins have a greater effect against a variety of non-communicable diseases, which was RESPONSIBLE for over 50-60% of deaths in developing countries.▪Biotechnology in Flora and FaunaBiotechnology develops the process of micropropagation system, a traditional method of plant breeding for producing many new plant species and of new varieties with highly desirable characteristics.Productions of genetically engineered plants with highly desirable characteristics have been produced. These crops result from the alteration in the genetic makeup of the crops and this modification leads to a number of potential advantages including the production of crops, quality of crops, increased nutritional qualities of food crops, improved taste, texture or appearance of food, reduced DEPENDENCE on fertilizers, pesticides and other agrochemicals and lot more.▪ Biotechnology in EnvironmentBiotechnology is also INVOLVED in controlling the environmental pollution through biodegradation of potential pollutants, recycling of wastes and other WASTE treatment technologies.Biotechnology plays a major role in monitoring and controlling the environmental pollutions through the biological applications including bioremediation, biomonitoring, biotreatment and biodegradation of all the solid, liquid and gaseous wastes. Apart from these, there are many other biotechnological treatments applied to monitor the different components of the environment.♥️♥️ |

Explain why plants have low energy needs as compared to animal |
|
Answer» do not need to move from ONE place to another. Movements in a PLANT are USUALLY at the cellular LEVEL and hence a far less amount of energy is required by plants. Animals, on the other hand, need to move from one place to another; in SEARCH of food. So, the energy need of animals is pretty higher than of plants.......... ✌ |

Write a brief note on external features of human heart |
|
Answer» External features of the heart: The division of the heart into FOUR cavities is indicated on its surface by grooves. The atria are SEPARATED from the ventricles by the coronary sulcus (auriculoventriculargroove); this contains the trunks of the nutrient vessels of the heart, and is deficient in front, where it is crossed by the root of the pulmonary artery. The interatrial groove, SEPARATING the two atria, is scarcely marked on the posterior surface, while anteriorly it is hidden by the pulmonary artery and AORTA. The ventricles are separated by two grooves, one of which, the anterior longitudinal sulcus, is situated on the sternocostal surface of the heart, close to its left margin, the other posterior longitudinal sulcus, on the diaphragmatic surface near the RIGHT margin; these grooves extend from the base of the ventricular portion to a notch, the incisura apicis cordis, on the acute margin of the heart just to the right of the apex. |

On the basis of cell dividing capacity classify plant tissues ---- No need to answer |
|
Answer» This topic GIVES an overview of; Tissues MERISTEMATIC Tissue Permanent Tissue Simple Permanent Tissue Complex Permanent Tissue Nervous Tissue Tissues In unicellular organisms, a single cell performs all basic functions. For example, in Amoeba, a single cell carries out movement, intake of food and respiratory gases, respiration and excretion. But in multi-cellular organisms there are millions of cells. Most of these cells are specialised to CARRY out a few functions. Each specialised function is taken up by a different group of cells. Since these cells carry out only a particular function, they do it very efficiently. In HUMAN beings, muscle cells contract and relax to cause movement, nerve cells carry messages, blood flows to transport oxygen, food, hormones and waste material and so on. In plants, vascular tissues conduct food and water from one part of the plant to other parts. So, multi-cellular organisms show division of labour. Cells specialising in one function are often grouped together in the body. This means that a particular function is carried out by a cluster of cells at a definite place in the body. This cluster of cells, called a tissue, is arranged and designed so as to give the highest possible EFFICIENCY of function. Blood, phloem and muscle are all examples of tissues. A group of cells that are similar in structure and/or work together to achieve a particular function forms a tissue. P |
