What are the three parts of the ear and their functions?
What are the three parts of the ear and their functions? The ear is divided into three main parts – the outer ear, the middle ear, and the inner ear. The inner ear is filled with fluid. The inner ear also contains the receptors for sound which convert fluid motion into electrical signals known as […]
Do elements in a period share chemical properties?
Do elements in a period share chemical properties? All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the […]
For which object would a geologist use carbon 14 dating to determine age?
For which object would a geologist use carbon 14 dating to determine age? The correct answer is – the first object, the animal skull. The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon. […]
Why does a rocket keep accelerating?
Why does a rocket keep accelerating? As the rocket velocity increases, it encounters air resistance, or aerodynamic drag, which opposes the motion. Drag increases as the square of the velocity. The thrust of the rocket must be greater than the weight plus the drag for the rocket to continue accelerating. Do Newton’s laws apply in […]

Why is a burette more accurate?
Why is a burette more accurate? Burettes are larger than a pipette, it has a stopcock at the bottom to control the release of liquid. Burette is similar like graduated cylinder and is easier to measure a required volume of liquid through graduations. But, it has large meniscus and hence its accuracy and precision is […]
Why do electrons do not fall in nucleus?
Why do electrons do not fall in nucleus? Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, […]
What are the three types of pain receptors?
What are the three types of pain receptors? Within the central nervous system, there are three types of opioid receptors which regulate the neurotransmission of pain signals. These receptors are called mu, delta, and kappa opioid receptors. What are the two types of pain fibers? Each of the spinal nerves emerging from the spinal cord […]
