Classification of Living Organisms Summary
Summary - Biologists estimate that there are about 30 million species of living organisms inhabiting this biosphere and only a million and half of it have been discovered and described so far. The species of plants and animals identified so far exhibit a great deal of variation ..
Classification of Living Organisms
Need for Classification - More than a million species of living organisms have been discovered and described so far and a large number of them are yet to be discovered. Scientists involved in this task, called taxonomists, estimate that there may be around 30 million species of ..
Diversity in Living Organisms Introduction
Introduction - Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolution. During the course of this evolution se..

Composition
The urine is a pale yellow coloured fluid. The yellow colour is due to the presence of urochrome pigment formed from the haemoglobin of dead RBC's in the liver cells. It is acidic in nature and has a pH of 6.0. It has a faint anamalic odour due to the presence of urinod. It soon gets a strong smel..
Diversity in Living Organisms - Test Questions
Question 1 - Question: What is the necessity of classification of organisms? Answer: Organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Therefore, classification i..
Structural Organization of the Cell
The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and cell organelles. In addition ..

Cell Structure
Each cell whether in a unicellular form like Gleocapsa or multicellular form like Nostoc, has a definite cell wall. Most often it is surrounded by a thin or thick mucilagenous sheath. The inner layer of cell wall has a chemical composition similar to bacterial cell, made up of peptidoglyc..

Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
I like the way this tutors double check the work with me and took time to explain each detail. It really helped me to better understand - Harry
