In biology, regeneration is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.[1] Every species is capable of regeneration, from bacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5] where after the necrotic tissue comes fibrosis.[5] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation, morphogenesis and cell differentiation.[6][7] Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traits allowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding. The hydra and the planarian flatworm have long served as model organisms for their highly adaptive regenerative capabilities.[9] Once wounded, their cells become activated and restore the organs back to their pre-existing state.[10] The Caudata ("urodeles"; salamanders and newts), an order of tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures.[2] The regeneration of organs is a common and widespread adaptive capability among metazoan creatures.[9] In a related context, some animals are able to reproduce asexually through fragmentation, budding, or fission.[8] A planarian parent, for example, will constrict, split in the middle, and each half generates a new end to form two clones of the original.[11] Echinoderms (such as the sea star), crayfish, many reptiles, and amphibians exhibit remarkable examples of tissue regeneration. The case of autotomy, for example, serves as a defensive function as the animal detaches a limb or tail to avoid capture. After the limb or tail has been autotomized, cells move into action and the tissues will regenerate.[12][13][14] In some cases a shed limb can itself regenerate a new individual.[15] Limited regeneration of limbs occurs in most fishes and salamanders, and tail regeneration takes place in larval frogs and toads (but not adults). The whole limb of a salamander or a triton will grow again and again after amputation. In reptiles, chelonians, crocodilians and snakes are unable to regenerate lost parts, but many (not all) kinds of lizards, geckos and iguanas possess regeneration capacity in a high degree. Usually, it involves dropping a section of their tail and regenerating it as part of a defense mechanism. While escaping a predator, if the predator catches the tail, it will disconnect

REGENERATION : When the simple animals like Hydra ,Planaria develop a new individual from their broken older part it is as regeneration. It is carried out by specialised cells which divide and differentiate to form the complete individual. These cells multiply and from this mass of cells other parts are generated. Regeneration follows an organised sequence referred to as DEVELOPMENT.

Following are the various advantages of tissue culture technique:

  1. The plantlets are obtained in a very short time with a small amount of plant tissue.

  2. The new plants produced are disease-free.

  3. The plants can be grown throughout the year, irrespective of the season.

  4. A large space is not required to grow plants by tissue culture technique.

  5. The production of new varieties in the market place speeds up.

  6. This technique is being used for the production of ornamental plants such as dahlia, chrysanthemum, orchids, etc.

Variation is the change in characters or traits of an individual which has not existed in their parents.
Variations can be of many types. If mutation occurs, there is a sudden change in the number or structure of genes or chromosomes. This change lasts generation after generation. For example, in the atomic bombing of Hiroshima and Nagasaki in 1945, the structure of genes of people changed. This is lasting till now. Moreover in disasters like Radioactive leakage, mutations can occur.
Variations lead to Evolution. This fact has lead to development of humans from ape.

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).... hope it would be helpful✌

1: Amoeba a unicellular organism found in stagnant water.

2: The size of amoeba is 0.25.

3:They move with the help of finger like projection called pseudopodia.

4: Cytoplasm is differentiate into two parts, outer portion is ectoplast and inner portion is called endoplast.

5.Amoebae are eukaryotes whose bodies most often consist of a single cell.

6. The cells of amoebae, like those of other eukaryotes, possess certain characteristic features.

7.Their cytoplasm and cellular contents are enclosed within a cell membrane.

8.Their DNA is packaged into a central cellular compartment called the nucleus..

Each amoeba contains a small mass of jellylike cytoplasm, which is differentiated into a thin outer plasma membrane, a layer of stiff, clear ectoplasm just within the plasma membrane, and a central granular endoplasm.

9. The endoplasm contains food vacuoles, a granular nucleus, and a clear contractile vacuole..

10.People usually become infected from warm freshwater lakes and rivers..

The set of resistors in any way is called the series combination. Connecting resistors of resistance R1 , R2 and R3 , we saw that, I in circuit is same but V in circuit = V1 + V2 + V3 Applying ohm's law, I/Rs = I/R1 + I/R2 + I/R3 This gives, Rs = R1 + R2 + R3 Hence proved that the equivalent resistance in series is equal to the resistance in the given resistors.

The zygote formed after fertilization in the fallopian tube is implanted in the uterus. It divides repeatedly to form a mass of cells known as an embryo. This embryo gets attached to the inner layer of the uterine cavity, i.e., endometrium. It thickens every month and is supplied with blood to nourish the embryo. Soon it gets covered by rapidly dir.iding uterine cells. This leads to pregnancy. 

Within a span of some months, the embryo starts developing limbs and begins to resemble a miniature human being. When all body parts of the embryo can be recognized, it becomes a fetus. When this fetus is fully developed, the mother gives birth to the baby.

Metal bicarbonate means metal hydrogencarbonate. Metal +Metal Hydrogen carbonate --> Salt+ CO2 + H2O. For example= NaHCO3(s) (Sodium Bicarbonate)(Metal BiCarbonate) + H2SO4(aq) (Sulphuric Acid)(Acid )---> Na2SO4(aq) (Sodium Sulphate)(salt) +CO2 (Gas) +H2O (water )

Translate the following chemical equation written in word into language of chemistry & balance them. (i) Sodium hydroxide + sulphuric acid → sodium sulphate + water (ii) Sodium carbonate + nitric acid → sodium nitrate +water + CO2 (iii) Potassium bicarbonate + sulphuric acid →potassium sulphate + water + CO2 (iv) Zinc +sodium hydroxide → sodium zincate + hydrogen (v) Aluminum +sodium hydroxide + water → sodium meta aluminate + hydrogen (vi) Potassium dichromate + hydrochloric acid → potassium chloride + chromium chloride +water + chlorine. (vii) Lead(II) nitrate → lead oxide +nitrogen dioxide +oxygen (viii) Ammonium sulphate + sodium hydroxide → nitrous oxide + water (ix) Ammonium sulphate +sodium hydroxide → sodium sulphate + ammonia +water (x) Potassium bromide + (c)phosphoric acid → potassium phosphate + hydro bromic acid

Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine and thyroxine. They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T₃ and T₄ are partially composed of iodine. Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
