Tesla & Edison were not the first to invent the light bulb, in fact it was a Canadian by the name ofMatthew Evanscreated and patented the DC (Direct Current) light bulb five years before he sold his patent toThomas Edisonin 1979

Laboratory testing of blood prior to transfusion is intended to ensure that recipients receive the safest possible blood products.

emulsification(in digestion) The breakdown of fat globules in the duodenum into tiny droplets, which provides a larger surface area on which the enzyme pancreatic lipase can act to digest the fats into fatty acids and glycerol.Emulsificationis assisted by the action of the bile salts (see bile). "emulsification."

•Egg yolk – in which the main emulsifying agent is lecithin. ...•Mustard – where a variety of chemicals in the mucilage surrounding the seed hull act as emulsifiers.•Soy lecithin is another emulsifier and thickener.•Pickering stabilization – uses particles under certain circumstances.

Some animals give birth to young ones while some animals lay eggs which later develop into young ones. Those animals which lay eggs are called oviparous animal

Physical development is the process that starts in human infancy and continues into late adolescent concentrating on gross and fine motor skills as well as puberty. Physical development involves developing control over the body, particularly muscles and physical coordination

The peak of physical development happens in childhood and is therefore a crucial time for neurological brain development and body coordination to encourage specific activities such as grasping, writing, crawling, and walking. As a child learns what their bodies can do, they gain self confidence, promoting social and emotional development.

a shopkeeper buys 10 eggs for 8 and sells 8 eggs for 10 .find his profit or loss percent

The mostimportantpart about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton'slawofuniversal gravitation.

Acompound microscopeis an instrument that is used to view magnified images of small objects on a glass slide. It can achieve higher levels of magnification than stereo or other low power microscopes and reduce chromatic aberration. It achieves this through the use of two or more lenses in the objective and the eyepiece.

Data: mass of the body = 1,000 kg Initial velocity (u) = 20 m/s Final velocity (v) = 0 m/s Displacement (S) = 50 m Force acting (F) =?Solution:

We know that F = ma and 2as=v2- u2 ⇒ 2 × a × 50 m = 02- 202

a= -4 m/s2now F = ma ⇒F = 1,000 × -4 = -4,0000N

Note: Negative symbol represents The opposit direction to the displacement.

correct answer is -4, 0000Nplease like❤❤❤️👍

pole is the correct answer

R = 20we know that R = 2fso f=R/2= 10cmu = -12cmso, by using mirror formula....1/f = 1/u + 1/v1/10=-1/12+1/v1/v = 1/10+1/121/v =11/60cmv = 60/11cm..........(A)here v represent position of the image from the mirroru represent position of the object from the mirror and f represent focal length.

Villi are small finger-like projections located in the wall of the small intestine. Their function is to increase the surface area in order to maximise the absorption of digested food.

the sound which is present for us is termed as music and the song which is in please unpleasant for our ears is termed as noise music can become noise when it crosses the bearable range for human ears

honking horns of vehicles, kitchen appliances, Crusher, machines, loud noise of machines from factories

We can use proper lubrication as well as better maintenance of machines to reduce noise pollution and improve efficiency.

Mercuryis the only one inliquidstate at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer.

A plant which fulfills its nitrogenous needs by eating insects is called an insectivorous plant.

Cause of eating of insects by plants:The soil of marshy land is deficient in nitrogen. Plants living in marshy areas do not get nitrogen from the soil. Their nitrogen need is fulfilled by sucking the juice of insects.

Example of insectivores plant arePitcher plant, Venus Fly trap, Bladderwort, Drosera etc

Roundworms (Platyhelminthes) havea tough covering of cuticle on the surface of their body. As a result,roundworms havea hydrostatic skeleton. This provides a counterforce for the contraction of muscles lining the pseudocoelom.

Nematodes do not have completely developed mesodermal linning cavities called coelom. they have cavities that are not formed completely by mesoderm. thus they are not true coelom and are known as pseudocoelom.
