Bsc1st year (2nd sem) 2020 4 paper pattern paper -ecology of botany- topic Ecosystem (the water cycle)

Ecosystem is a part of ecology in which we study the basic function and reactions going on in atmosphere , it's main function is to study about life i.e..,biological community of interacting organisms and their physical environment , with it's consisting life cycle ..........the water cycle , phosphorous cycle , carbon cycle , nitrogen cycle sulfur cycle etc ............this part sum-ups with the water cycle (The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth) With the help of various sought of diagrams and the mechanism to make it's study simple and grounded

Bsc1st year (2nd sem) 2020 4 paper pattern paper- Botany paper biostatics- Topic Mode

It's main focus is to concentrate the important topic such as measure of central tendency , mean , median and mode ( it's types , merit & limitations ) some of the illustration through examples with the chart construction and an add on shortcut methods . It's introduction with some of the definations given by scientists , other two parts are median and mean uploded with their defination , history , types examples and question papers . This is very important topic of biostatistics summing up with it's disruptive and discipline explanation . The mode of a set of data values is the value that appears most often. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled

bsc zbc( 1st sem )ecology topic carbon cycle

The series of processes by which carbon compounds are inter converted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. This process focus upon the ecological carbon cycle with it's diagram.........it's basically the second clip , first clip is that of the water cycle

Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength . Spectrophotometry. A spectrophotometer is an analytical instrument used to quantitatively measure the transmission or reflection of visible light, UV light or infrared light. ... Spectrophotometers are widely used in various disciplines such as physics, molecular biology, chemistry and biochemistry.Spectrophotometry. Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength.The spectrophotometer works by passing a light beam through a sample to measure the light intensity of a sample. These instruments are used in the process of measuring color and used for monitoring color accuracy throughout production. They are primarily used by researchers and manufacturers everywhere.There are two basic types of atomic spectrometers: emission and absorbance. In either case a flame burns the sample, breaking it down into atoms or ions of the elements present in the sample. An emission instrument detects the wavelengths of light released by the ionized atoms.

Part one of Molecular orbital theory (chemistry)

In chemistry, Molecular orbital (MO) theory is a method for describing the electronic structure of molecules using quantum mechanics. Electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule . Molecular orbital theory assumes the wave nature of electrons ,thus during the overlapping the wave functions of different atoms interact in two ways- Destructive interference and constructive intereference. The molecules possesing higher number of bonding electrons are more stable.Molecular orbital theory is more powerful than valence-bond theory because the orbitals reflect the geometry of the molecule to which they are applied. But this power carries a significant cost in terms of the ease with which the model can be visualized.Basically molecular orbital (MO) theory is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule.
