    Hydroponics is a subset of hydroculture, which is a method of growing plants without soil by using mineral nutrient solutions in a water solvent.[1] Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients used in hydroponic systems can come from an array of different sources; these can include, but are not limited to, byproduct from fish waste, duck manure, or purchased chemical fertilisers.

    Cell envelope is a combination of the cell membrane, cell wall, and an outer membrane if it is present. Usually, this envelope is a characteristic of prokaryotes like bacteria. Hence, the composition would be cell membrane, bacterial cell wall and bacterial outer membrane (made of glycocalyx).

    Primary adrenal insufficiency is caused by the destruction of the adrenal gland. Idiopathic adrenal atrophy is the most common cause of adrenal insufficiency. It is not known exactly why this occurs, but it is believed to be related to an autoimmune response that results in the slow destruction of adrenal tissue. Addison's disease, also called adrenal insufficiency, is an uncommon disorder that occurs when your body doesn't produce enough of certain hormones. In Addison's disease, your adrenal glands, located just above your kidneys, produce too little cortisol and, often, too little aldosterone.

    Your body has a huge system involved in the sensation and control of blood pressure, not only within the kidneys, but all over the body - especially in times of great need. This is in contrast to a smaller system called tubuloglomerular feedback, which you can think of as the system that senses and controls blood pressure and glomerular filtration rate within the kidneys on a moment-by-moment basis. When called upon, this smaller system can also rev up the really big system I'm about to get into. The most important system involved in the regulation of systemic blood pressure, renal blood flow and glomerular filtration rate is called the renin-angiotensin-aldosterone system, or (RAAS) for short.

    The mitochondrion consists of an outer membrane, an inner membrane, and a gel-like material called the matrix. This matrix is more viscous than the cell's cytoplasm as it contains less water.
    The mitochondrial matrix is a viscous fluid that contains a mixture of enzymes and proteins. It also comprises ribosomes, inorganic ions, mitochondrial DNA, nucleotide cofactors, and organic molecules. The enzymes present in the matrix play an important role in the synthesis of ATP molecules.

Put differently, growth is the most fundamental characteristics of living bodies accompanied by various metabolic processes that take place at the cost of energy. The processes can be anabolic or catabolic.

    If a normal plant cell is placed in a hypertonic solution , the shrinkage od protoplasm away from its cell wall takes place . This process is called plasmolysis. Hypertonic solution - When the surrounding solution possesses higher osmotic pressure than that of the cell sap. Hypotonic solution - When the surrounding solution possesses lower osmotic pressure than that of the cell sap. Isotonic solution - When the osmotic pressure of the surrounding solution and that of he cell sap is same.

    Plasmolysis-contraction of the protoplast of a plant cell as a result of loss of water from the cell. Hypotonic-hypotonic solution is a water that is less-concentrated than the cell the water surrounds. Hypertonic-hypertonic solution is basically the opposite of a hypotonic solution. In this case, the water has more of a solute than the cell does.

    The metabolic pathway of electron transport is called as electron transport system or ETS.
    Glycolysis and Krebs cycle result in the formation of reduced coenzymes such as 10 molecules of NADH +H+ ions and 2 molecules of FADH2 and 4 molecules of ATP. These reduced coenzymes need to be oxidized to release energy stored in them. This is possible by the transport of electrons and protons from these coenzymes to oxygen through electron carriers present in the inner mitochondrial membrane. This metabolic pathway of electron transport is called as electron transport system or ETS. 
      
    ETS comprises of several energy carriers which include NADH dehydrogenase complex (Complex I), Ubiquinone (Complex Q), Succinate dehydrogenase complex (complex II), Cytochrome bc1 complex (Complex III), Cytochrome c, Cytochrome c oxidase (Complex IV)

    Steps in ETS:
    * Electrons are transferred from NADH+H+ to Ubiquinone through complex I and protons are moved from mitochondrial matrix to intermembrane space.
    * Electrons from FADH2 are transferred to Ubiquinone through complex II and protons are moved from mitochondrial matrix to intermembrane space.
    * Ubiquinone transfers the electrons to complex III.
    * Complex III transfers electrons to complex IV through Cytochrome c. Some protons are moved from mitochondrial matrix to intermembrane space.
    * Complex IV contains Cytochrome a and Cytochrome a3. It transfers the electrons to final acceptor, the oxygen.
    * Oxygen combines with 2 H+ ions and reduces to water which drives ETS.
    2H+ + 2e- + ½ O2   --------- H2O + Energy

    Centrosome is also called as the 'cell centre'. Centrosome is a rod like organelle occurring near the nucleus. Centrosome is formed by 2 centrioles, each being formed by 9 triplet microtubules in 9+0 arrangement encloses structures called as centrioles. It helps the cell during cell division by the formation of spindle fibres. It is specifically present in animal cells only.
    Centriole as an organelle is made to use in organizing the mitotic spindle and completing the cytokinesis. At one point in time, centrioles were believed to be necessary for the creation of mitotic spindle in the <a href="https://byjus.com/biology/animal-cell/">animal cell</a>. Although, many fresh experimentations established that the cell which does not have a centriole (surgically removed through laser) could function without them in the G1 level of interphase and then the centriole could be created in the future in a de novo manner.

    Although bile juice does not contain any digestive enzymes, it helps in the digestion of fats. Bile juice has some bile pigments. These break down large fat globules into smaller globules so that the pancreatic enzymes can easily act on them. This process is known as emulsification of fats.
