s are integumentary structures..It is present in birds..Once i was present inorder to provide INSULATION from cold weather.birds then used it for flight.Three types of FEATHERS are:1.Quill feathers: fiund on tails and wings for flight2.contour feathers: COVERS the body3.Filoplumes: LYING between contour feathers

rocess R is respiration.2.The circulatory SYSTEM is DESCRIBED in the above comprehension.3.If there are no folds at the lining of lungs then the TOTAL SURFACE is not enormous.''P''⇒ALVEOLI''Q''⇒BLOOD.

in DIGESTION of PROTEIN,FAT and carbohydrated in the SMALL INTESTINE

the ANSWER.............

ic UNIT of life is CELL.. It is the STRUCTURAL and FUNCTIONAL unit of life..

itis is a COMMON eye condition recongnized  by OFTEN  inflammation of the eyelid, the part where eyelashes grow  and SMALL OILY glands near the BASE of the eyelashes don't function properly, resulting in inflamed, irritated, itchy, and reddened eyelids.It is  caused by excess growth of bacteria  that is ordinarily found on the skin  and sometimes allergies. A number of diseases and conditions can lead to blepharitis.

OBINI am great because i am binding oxygen and carbondioxide in respiration in all living organisms to make their life possible on the EARTH.CHLOROPHYLLI am GREATER than U because i utilize CO₂ from respiration and release O₂ into the ATMOSPHERE and support life on the earth and also prepare food for the entire WORLD.

in is an organic COMPOUND and a vital NUTRIENT that an ORGANISM requires in limited amounts. An organic chemical compound is called a vitamin when the organism cannot synthesize the compound in sufficient quantities.Carbohydrates are one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs.PROTEINS are ESSENTIAL nutrients for the human body.They are one of the building blocks of body tissue, and can also serve as a fuel sourceFat is one of the three main macronutrients: fat, and carbohydrates ,proteins Fats are a wide group of compounds whose basis is in long-chain organic acids, calledfatty acids

is an amphibian, but adult frogs do not have gills. They absorb oxygen from the WATER through their skins, using special blood vessels. If the oxygen level in water is too low, frogs will move AROUND to increase the water flow ACROSS the SKIN. Some frogs have creased skins that can increase their surface area.This TYPE of respiuration is called cutaneous respiration

s HANG Out in WATER and Fat. There are TWO types of vitamins: fat soluble and water soluble. When you eat foods that contain fat-soluble vitamins, the vitamins are STORED in the fat TISSUES in your body and in your liver. They wait around in your body fat until your body needs them.

e INCREASE of CO₂ concentration in the atmosphere increases photosynthesis. CO₂ is one of the factor that INFLUENCES photosynthesis.

ytic plants has special charcterstic to perform photosynthesis . to perform photosynthesis we need CO2,H2O,SUNLIGHT chlorophyll. all plants get CO2 from ATMOSPHERE, SUN light from sun, chlorophyll already present in plant,WATER absorbed from roots. xerotphytic plants also get all of these sufficiently except water because they grow in water scarcity areas . so they store water in STEMS and trunks and they don t allow so much transpiration. thus they perform photosynthesis

the main site of photosynthesis due to following ways : -⇒ presence of HIGH amount of CHLOROPHYLL .( ABSORBS light energy  )⇒ presence of transparent epidermis ( which allows sunlight to reach chloroplast )  .⇒ only  the LEAF stomata are present  .( for gaseous exchange & transpiration ) ⇒ leaf are exposed toward sunlight .       by the above points it is clear that leaf is the main site for photosynthesis.

ll INTESTINE is about 20 FEET long and about an INCH in diameter.

ration is the cause which provides a cooling effect to plants. When the water from the aerial parts , EVAPORATE from the surface , they take up the heat from the PLANT to get converted into water vapour , thus providing a cooling effectA plant WILTS if it's short of water as it provides TURGIDITY to the cell and keeps the plant in correct posture

of migration COULD be :-- It can too MUCH INCREASE or decrease the population of a region.- Too much migration can make a region totally EMPTY and the other over CROWDED..

ung MIGRATORY BIRDS are born with an innate map which gives them the clear route and they can MIGRATE WITHOUT the help of their parents.these things were researched by many SCIENTISTS.

on is a PROCESS through which animals travel LONG distances to SURVIVE from them weather CHANGE. for example siberian birds

tern STERNA is the LONGEST migration route BIRD.

y birds FLY very FAST . During a CHASE however, speeds increase; ducks, for example, can fly 60 MPH or even FASTER, and it has been reported that a Peregrine Falcon can stoop at speeds of 200 mph (100 mph may be nearer the norm)

monds are soaked in water their NUTRITIONAL value increases.This makes our BODY to easily absorb all the nutrients in the almond which is soaked in water than normal ONE.

S: either of two external openings of the nasal cavity in vertebrates that admit air to the lungs and smells to the olfactory nerves.NASAL CAVITY: The nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face. Eachcavity is the continuation of one of the two nostrils.PHARYNX:the membrane-lined cavity behind the nose and mouth, connecting them to the oesophagus.LARYNX:the hollow muscular organ FORMING an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box.TRACHEA:a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.BRONCHUS:any of the major air passages of the lungs which DIVERGE from the windpipe.BRONCHIOLES:any of the minute branches into which a bronchus divides.ALVEOLI:any of the many tiny air sacs of the lungs which allow for RAPID GASEOUS exchange.

't SNEEZE when you LOOK at the SUN, it is just a COINCIDENCE, you sneeze when ever your nose feels like it.

that we get from shops aren't alive.They are not FERTILE eggs.Some eggs that are laid by birds or animals that gives rise to formation of progeny by fertilization and cleavage PROCESS are LIVING ONE.

f PARASITIC Plants-Holoparasites -   MISTLETOES.   ROOT parasites.     Nonphotosynthetic VINES     Nonphotosynthetic stem parasites. Hemiparasites

arasitic plant:FULLY parasitic plants obtain some or all the NUTRIENTS from other LIVING organismeg.cuscutasemi parasitic plantsobtaining some food from host but undergoes photosynthesis at the same timeeg.mistletoe

spinal FLUID is the fluid PRESENT inside and OUTSIDE the BRAIN.

wing eyelashes you can use Vaseline.. APPLY a small QUANTITY on your eyelashes at NIGHT ... You will see the DIFFERENCE in about 1 MONTH..

is the SPONTANEOUS movement of water molecules across a selectively PERMEABLE membrane from the region of its HIGH to LOW concentration.:)

is the spontaneous net movement of SOLVENT molecules through a semi-permeable membrane into a region of higher SOLUTE concentration, in the direction that TENDS to EQUALIZE the solute concentrations on the two SIDES.
