What is the significance of reference point for measuring distance? A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a […]
How does nuclear energy benefit the environment?
How does nuclear energy benefit the environment? Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels. […]
Can mitosis ever be used for human reproduction?
Can mitosis ever be used for human reproduction? In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. This is classified as asexual reproduction because it does not require sex for the creation of new organisms. What cells does mitosis not occur in? You read […]
What is the main drawback of filament lamp?
What is the main drawback of filament lamp? The major disadvantage associated with filament bulbs is its cost.

What are the 4 types of equilibrium?
What are the 4 types of equilibrium? There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of […]

What are two different types of electron microscopes?
What are two different types of electron microscopes? There are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image. What is the greatest advantage of […]
