Does a low pitch sound have a low frequency?
A sound wave, like any other wave, is introduced into a medium by a vibrating object. The vibrating object is the source of the disturbance that moves through the medium. The vibrating object that creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker. Regardless of what vibrating object is creating the sound wave, the particles of the medium through which the sound moves is vibrating in a back and forth motion at a given frequency. The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. If a particle of air undergoes 1000 longitudinal vibrations in 2 seconds, then the frequency of the wave would be 500 vibrations per second. A commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor. The first particle of the medium begins vibrating, at say 500 Hz, and begins to set the second particle into vibrational motion at the same frequency of 500 Hz. The second particle begins vibrating at 500 Hz and thus sets the third particle of the medium into vibrational motion at 500 Hz. The process continues throughout the medium; each particle vibrates at the same frequency. And of course the frequency at which each particle vibrates is the same as the frequency of the original source of the sound wave. Subsequently, a guitar string vibrating at 500 Hz will set the air particles in the room vibrating at the same frequency of 500 Hz, which carries a sound signal to the ear of a listener, which is detected as a 500 Hz sound wave.
Water freely moves through a phospholipid bilayer Why is this unexpected?
It moves through the bilayer via channels. These channels often are for transfer through the bilayer for other chemicals (sodium, potassium, etc) but also allow water to flow through readily. It is unexpected because water is hydrophilic (obviously- all charged molecules are). The phosphate part of the bilayer can bind with water, but the lipid on the inside of the bilayer acts like a layer of oil on the surface of the water- water cannot pass through the hydrophobic lipid.
What is a grained paper?
Most paper has what we call a "grain direction"; it used to be thought that the grain direction was due to paper fibers being aligned in that direction in the paper-making process, but current thinking is that it is more strongly related to what tension the paper was under as it dried. Handmade papers which were dried between felts often do not have a pronounced grain direction. When a paper does have a pronounced grain direction, as most modern machine-made papers do, it will bend or fold more easily with the grain than across it. If you dampen one side of such a paper, it will curl into a tube with the grain. Most commercial papers are sold "grain long" -- that is, the grain runs the long way, from top to bottom on the sheet. (Putting these things together, if you take a sheet of commercial US printer paper and dampen it on one side, it'll curl up with the grain, resulting in an 11-inch-long tube.)
Microscopic particle that invades a cell and often destroys it?
A virus is a microscopic being that can invade and destroy a cell. Viruses have some, but not all, of the characteristics of living things.
What is the method by which heat is transferred into in a fluid liquid or gas?
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
What is the meaning of kanika?
"Kanika" is a Hindu name that means "small particle" or "grain." It is often used to signify something delicate or precious.
What is a grain elevator?
A grain elevator is a tall building that often stands around 400 feet tall that is used to store grain prior to shipping out on a train or by truck. Using a series of augers and chutes, grain, which is dumped through a grate in the floor by the truck that goes through an drive-through opening in the building, is moved into a storage unit. When a truck or train comes to pick up the grain and ship it somewhere else, a spout from above is used to pour the grain into the box of the truck or the car of the train. Then the grain is shipped away.

What in the air influence the speed of sound?
A sound wave is a pressure disturbance that travels through a medium by means of particle-to-particle interaction. As one particle becomes disturbed, it exerts a force on the next adjacent particle, thus disturbing that particle from rest and transporting the energy through the medium. Like any wave, the speed of a sound waverefers to how fast the disturbance is passed from particle to particle. While frequencyrefers to the number of vibrations that an individual particle makes per unit of time, speed refers to the distance that the disturbance travels per unit of time. Always be cautious to distinguish between the two often-confused quantities of speed (how fast...) and frequency (how often...).Since the speed of a wave is defined as the distance that a point on a wave (such as a compression or a rarefaction) travels per unit of time, it is often expressed in units of meters/second (abbreviated m/s).Air is a mixture of gases ! And gases is matter with physical properties, as absorption of sound waves, for example.Density and humidity.

Is waves noun?
Yes, "waves" is a noun. It refers to a disturbance that moves through a medium, often described as the movement of energy through water or air in the form of a wave.
