is a modified polysaccharide that contains nitrogen; it is synthesized from units of N-acetyl-D-glucosamine (to be precise, 2-(acetylamino)-2-deoxy-D-glucose). These units form covalent β-(1→4)-linkages (like the linkages between glucose units forming cellulose). Therefore, chitin may be described as cellulose with one hydroxyl group on each monomer replaced with an acetyl amine group. This allows for increased hydrogen bonding between adjacent polymers, giving the chitin-polymer matrix increased strength.A cicada emerges from its chitinous larval exoskeleton.In its pure, unmodified form, chitin is translucent, pliable, RESILIENT, and quite tough. In most arthropods, however, it is often modified, occurring largely as a component of composite materials, such as in sclerotin, a tanned proteinaceous matrix, which forms much of the exoskeleton of insects. Combined with calcium carbonate, as in the shells of crustaceans and molluscs, chitin produces a much stronger composite. This composite material is much harder and stiffer than pure chitin, and is tougher and less brittle than pure calcium carbonate.[4] Another difference between pure and composite forms can be seen by comparing the flexible body wall of a CATERPILLAR (mainly chitin) to the stiff, light elytron of a beetle (containing a large proportion of sclerotin).[5]In butterfly wing scales, chitin is organized into stacks of gyroids constructed of chitin photonic crystals that produce various iridescent colors serving phenotypic signaling and communication for mating and foraging.[6] The elaborate chitin gyroid construction in butterfly wings creates a model of OPTICAL devices having potential for innovations in biomimicry.[6] Scarab beetles in the genus Cyphochilus also utilize chitin to form extremely thin scales (five to fifteen micrometres thick) that diffusely reflect white light. These scales are networks of randomly ordered filaments of chitin with diameters on the scale of hundreds of nanometres, which serve to scatter light. The multiple scattering of light is thought to play a role in the unusual whiteness of the scales.[7][8] In addition, some SOCIAL wasps, such as Protopolybia chartergoides, orally secrete material containing predominantly chitin to reinforce the outer nest envelopes, composed of paper.[9]Chitosan is produced commercially by deacetylation of chitin; chitosan is soluble in water, while chitin is not.[10]Nanofibrils have been made using chitin and chitosan.[11]PLZ MARK AS BRAINLIEST.

here is your answer Explanation:Both humans and ANIMALS have opiate receptors in the brain. These receptors act as action sites for different types of opiates such as heroin and morphine.The reason the brain has these receptor sites is because of the existence of endogenous (internal) neurotransmitters that act on these receptor sites and produce responses in the body that are similar to those of opiate drugs.Opiates WORK by binding to specific receptors in the brain, thus MIMICKING the effects of pain-relieving CHEMICALS that are produced naturally. These drugs bind to opiate receptors in the brain, spinal cord, and other locations in the body. By binding to these receptors, they BLOCK the perception of pain. Opiates can block pain and cause feelings of well-being, but they can also cause side effects such as nausea, confusion, and drowsiness.

e Halophiles ?Halophiles are salt‐loving organisms that inhabit SALINE and hypersaline environments and INCLUDE PROKARYOTIC (archaeal and bacterial) and eukaryotic organisms.Halophiles are useful for cleaning up polluted environments. WASTE water with salt concentrations more than 2% is ideal for halophiles to remove organic pollutants from. For instance, halophiles have been shown to remove phenol (a poisonous chemical) from their environments.They belong to bacteria .

Explanation:Fruit Types and Classification of Fruits Introduction Although most of us have a good idea what fruits and vegetables are when we eat them, it would be difficult provide a definition for someone of just what makes one food a vegetable and another a fruit. For a BOTANIST, the definitions are easier; a fruit is a reproductive structure of an angiosperm which develops from the ovary and accessory tissue, which surrounds and protects the seed. Fruits are important in seed dispersal. A vegetable is a part of one of the vegetative organs of the plant: roots, stems or leaves, or shoot systems. There are a few "vegetables which are difficult; broccoli and cauliflower are inflorescence buds, and artichokes are the ENTIRE inflorescence. Since flowers, the reproductive organ of the plant produce fruits and seeds, perhaps those vegetables which are inflorescences are more similar to fruits than they are vegetables. No matter what we call our nutritious dietary components, in botany what constitutes a fruit is straightforward, and this lab looks at the structure and classification of fruits. The process of fertilization initiates both seed and fruit development. While seeds develop from the ovules, the ovary tissue undergoes a series of complex changes which result in the development of the fruit. Many fruits are "fleshy" and contain sugars which attract animals who then disperse the enclosed seeds to new locations. Other, non-fleshy, fruits use other mechanisms for seed dispersal. In some plants, fruits can develop without fertilization. This is called parthenocarpy, and such fruits are seedless. As the ovary develops into a fruit, its wall OFTEN thickens and becomes differentiated into three, more or less distinct, layers. The three layers together form the pericarp, which surrounds the developing seed or seeds. The three fruit layers are: • Exocarp, the outermost layer often consisting of only the epidermis • Mesocarp, or middle layer, which varies in thickness • Endocarp, which shows considerable variation from one species to another Materials Required per pair of students and for Demonstration • Fresh snap beans or garden peas. Other available legumes may be substituted. • Dry and soaked corn grains • Tomatoes, cranberries or grapes • Peaches, plums, or cherries • Apples, PEARS, or quinces • In addition, an assortment of various kinds of fruits that are available should be available for demonstration. Dry and fleshy fruits of different types should be provided, as should aggregate and multiple fruits. Exercise 1 Classifying Fruits All fruits may be classified into three major groups on the basis of the number of ovaries and the number of flowers involved in their formation. The following outline includes most of the common types of fruits. A simple key to classifying fruits is provided here. Use these descriptions and the "Key to Fruit Types" provided to identify the types of fruits you will be observing in the lab. - 2 - A. Simple Fruits. Simple fruits develop from a single matured ovary in a single flower. Accessory fruits have some other flower part united with the ovary. 1. Fleshy Fruits, pericarp fleshy at maturity a. Berry, consisting of one or more carpels with one or more seeds, the ovary wall fleshy (1) Pepo (an accessory fruit), a berry with a hard rind, the RECEPTACLE partially or completely enclosing the ovary (2) Hesperidium, a specialized berry with a leathery rind b. Drupe, a stone fruit, derived from a single carpel and containing (usually) one seed. Exocarp a thin skin c. Pome (an accessory fruit), derived from several carpels, receptacle and outer portion. of pericarp fleshy, inner portion of pericarp papery or cartilaginous, forming a core d. Hip (an accessory fruit), several separate carpels enclosed within the fleshy or semi-fleshy receptacle 2. Dry Fruits, pericarp dry at maturity a. Dehiscent fruits, those which dehisce or split open when fully mature (1) Follicle, composed of one carpel and splitting along a single suture (2) Legume, composed of a single carpel and splitting along two sutures (3) Capsule, composed of several carpels and opening at maturity in one of four ways: (a) Along the line of carpel union (septicidal dehiscence) (b) Along the middle of each carpel (loculicidal dehiscence) (c) By pores at the top of each carpel (poricidal dehiscence) (d) Along a circular, horizontal line (circumscissle dehiscence) (4) Silique, composed of two carpels which separate at maturity, leaving a persistent partition between them

reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the ORIGINAL and its copy will be the same, except for rare mutations. They are clones. The main process of asexual reproduction is mitosisAsexual reproduction occurs when an organism makes more of itself without EXCHANGING genetic information with ANOTHER organism through sex.UF YOU ARE SATISFIED WITH MY ANSWER THEN PLEASE MARK ME AS BRAINLIST ANSWER
