It is was Albert Einstein, but interesting to know that his own theory predicts that universe is expanding, for making it stable he adds cosmological constant, in Field Equation

The method of producing thousands of plants through tissue culture is called micro propagation.

Each of these plants will be genetically identical to the original plant. Hence they are called ‘Somaclones’. Tomato and banana are produced through micro propagation for commercial purposes.

Thebasis for groupingorganismsinto five kingdomare, (i) Whether the organisms are made of prokaryotic or eukaryotic cells. (ii) Whether the organism is unicellular, i.e., a cell living singly or organizedintomulticellular and thus complex organisms.

Bacteria called RHIZOBIUM present in the root nodules of leguminous plants can convert atmospheric nitrogen into water soluble nitrogen compounds called NITRATES.

The flow of energy between various components of the environment occur as : Solar energy is trap and fixed by the producers (plants) and is converted into biomass.

Primary consumer (Herbivore) absorbs this stored energy in plants through digestion and transforms it into the form of energy that they are needed.

Secondary consumer (carnivore) consume primary consumer and absorbed the stored energy through the process of digestion.

The last link in the food chain is that of decomposer which break down organic matter of the top consumer and release it into the soil. They also break down plants, herbivores and carnivores that are not eaten by organisms on the food chain.

The follow of energy in an ecosystem at each trophic level and each time about 90% of the energy is lost, which is being lost as heat into the environment and some lost as incompletely digested food.

At each trophic level about 10% of the energy the previous trophic level is passed to the next food chain. This is known as 10% law.

Procedure:

Remove a green leaf from a plant that has been exposed to sunlight for a few hours

Half-fill a 250cm3 beaker with water. Heat the water until it boils. Keep the water at boiling point.

Use the forceps to place the leaf in the boiling water. Boil for 2 minutes.

Turn off the Bunsen Burner. (If you are using a heat source without a naked flame - electric water bath or hot plate - this step is unnecessary.)

Place the boiled leaf in a boiling tube containing 90% ethanol.

Place the boiling tube in hot water and boil for 10 minutes or until the leaf decolourizes. ( It may be necessary to replace the ethanol)

Gently remove the leaf and wash with a fine trickle of cold tap water.

Spread the leaf evenly on a white tile.

Add a few drops of iodine/potassium iodide solution to the leaf and note any observations

Ans :- Yes, cellular organisation is the basic characteristic of all living organisms.

Exceptions :- Viruses and Viroids (Made up of single strand of RNA or DNA, acellular structure.

Emasculation of a human male is the removal of both the penis and the testicles, the external male sex organs. Depending on the context, this may be seen as consensual body modification, or non-consensual genital mutilation.

A meiocyte is a type of cell that differentiates into a gamete through the process of meiosis. Through meiosis, the diploid meiocyte divides into four genetically different haploid gametes. The control of the meiocyte through the meiotic cell cycle varies between different groups of organisms.

This is because anti bacterial medicines block the formation of cell wall of the bacteria. When, bacterias dont have cell wall, they dont divide and hence they die. While, viruses dont have their machinery of own. When they enter into our body, they use our cells as their machinery. So, to kill viruses we've to kill some of our cells as well. Hence, making anti-viral drugs is more difficult than making anti-bacterial drugs.

Bacterial DNA is likely stable but viral DNA is mutate at faster rate so we can't make antiviral medicine

The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this model, there is a lipid bilayer in which the protein molecules are embedded. The lipid bilayer gives fluidity and elasticity to the membrane.

The two scientists, the work of which lead to this virus was Ivanovoski and Beijernick

Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle. Bacteria are retained by such filters, a new world was discovered: filterable pathogens.

Diarrhoea is the frequent passage of loose, watery, soft stools with or without abdominal bloating, pressure, and cramps.

Diarrhoea can be treated at home and it will resolve itself in a few days. Drink plenty of fluids, and follow the "BRAT" diet (bananas, rice, apple sauce and toast) to help ease symptoms. Take care to ensure infants and children stay hydrated. Electrolyte solutions such as Pedialyte can be helpful.

if nucleus will be removed following things can happen:# the cell will not be able to function properly # the cell will not be able to divide # the cell may diethis is because the nucleus is said to be the "brain of cell" if it is removed all the functions will stop

the cell will not be able to work

Nucleus is the main head of the cell which determines the way and function the cell will carry out. If nucleus is removed then the cell will not able to work, reproduce ,perform chemical reaction etc. .

If Nucleus Is Removed:1. No metabolic activities can be carried out in cell.2. Cell will die.3. It will not divide.

Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin.

Thus Saliva contains enzyme that help in digestion

Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes areproteins, and therefore are folded chains of amino acids with a specific shape.Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit. The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.

Coenzymes aresmall molecules. They cannot by themselves catalyze a reaction but theycanhelp enzymes todoso. In technical terms,coenzymes areorganic nonprotein molecules that bind with the protein molecule (apoenzyme) to form the active enzyme (holoenzyme).

Liver se bile juice nikalta hai

Medical Definition of Bile

Bile:Bile is a yellow-green fluid that is made by the liver, stored in the gallbladder and passes through the common bile duct into the duodenum where it helps digest fat. The principal components of bile arecholesterol, bile salts, and the pigment bilirubin.

An imbalance between these components of bile leads to the formation ofgallstones. Gallstones can thus be composed of different materials. Cholesterol gallstones form when there is an imbalance between the amounts of cholesterol and the bile salts. Cholesterol is normally kept in liquid form by the dissolving action of the bile salts. An increased amount of cholesterol in the bile overwhelms the dissolving capacity of the bile salts and leads to the formation of cholesterol gallstones. Similarly, a deficiency of bile salts promotes cholesterol gallstone formation. Pigment gallstones are frequently associated with chronic infection in the bile, especially in certain Asian countries where parasitic infection of the bile ducts is common. Patients with blood diseases that cause excessive breakdown of red blood cells can have increased amounts of bilirubin (breakdown product of red cells) in the bile, thus causing bilirubin gallstone formation.

Bacteria are classified by direct examination with thelight microscopeaccording to their morphology and arrangement.

The basic forms are spheres (coccus) and round-ended cylinders (bacillus). But there may be others such as helically twisted cylinders (spirochetes), cylinders curved in one plane (Selenomonads) and unusual morphologies (such as the squareArchaeaHaloquadratum). They also conform diplos, tetrads, staphylos, streptos, palizadas etc.

Bacteria are microscopic living organisms, usually one-celled, that can be found everywhere. They can be dangerous, such as when they cause infection, or beneficial, as in the process of fermentation (such as in wine) and that of decomposition.

Blood vessels function to transport blood. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95–100%) with oxygen. In all veins apart from the pulmonary vein, the saturation of hemoglobin is about 75%. (The values are reversed in the pulmonary circulation.) In addition to carrying oxygen, blood also carries hormones, waste products and nutrients for cells of the body.

Blood vessels do not actively engage in the transport of blood (they have no appreciable peristalsis). Blood is propelled through arteries and arterioles through pressure generated by the heartbeat.
