In order to attain stability, the elements such as carbon and hydrogen need <em>4 and 7 electrons</em> respectively.

As the elements such as carbon and hydrogen are in need of electrons, they are called anions (the electron gaining substances) and they gain required electron from <em>the cations,</em> the substance which readily losses electrons.

As far as carbon is concerned, as it can readily accept four electron, it need <em>four atoms</em> of cations.

In a musical instrument, sound waves build up by constructive interference until they are loud enough to hear. This concept is k
zalisa [80]

Answer:

The right answer to the concept whereby sound waves undergo constructive intereference to producing a louder sound in musical instrument would be superimposition.

Explanation:

When sound waves are produced, especially from a musical instrument, numerous beats are produced, which have different frequencies. The sound waves mix with each other in any of Destructive or constructive interference. When the waves are moving in the opposite direction with the same amplitude, they tend to cancel out each other to produce a quieter sound wave. The constructive interference of sound waves results in a wave with an accumulated amplitude of individual waves, thereby producing a louder sound wave. When sound waves are in combination into a higher amplitude is called superimposition.

Match the names of the microscope parts in column A with the descriptions in column B. Place the letter of your choice in the sp
mezya [45]

Answer:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Explanation:

The microscope is an essential equipment used in science laboratories to view objects which are too small to be seen by the naked eye. Also certain processes which occur at the microscopic level can only be observed using a microscope.

There are many different types of microscopes. The compound light microscope is the one most commonly used in biological laboratories to view tissues and cells of organisms. It uses visible light which passes through two separate lens to magnify the image produced of a specimen.

The various parts of compound light microscope and their respective functions are given below:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Stage ---> Platform that supports a microscope slide

Stage (slide) clip ---> Holds a microscope slide in position
