What is critical period in development? What is the critical period? Also known as the sensitive period, the critical period is a time during early postnatal life when the development and maturation of functional properties of the brain, its ‘plasticity’, is strongly dependent on experience or environmental influences. What are the five main areas of […]
Can you filter out phosphates?
Can you filter out phosphates? Reverse Osmosis is one of the most common and effective methods used for treatment and removal of Phosphates in drinking water. The heart of the system is the Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but […]

What are the major tissues in the respiratory system?
What are the major tissues in the respiratory system? The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells. Do lungs have nervous tissue? The lungs are innervated by the parasympathetic and sympathetic nervous systems, which […]
Do standing waves move?
Do standing waves move? Standing wave, also called stationary wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency. Does resonance cause standing waves? Standing waves are always associated with resonance. Resonance can be identified by a dramatic increase in amplitude of the resultant vibrations. Any system in which […]
What is circumference of cylinder?
What is circumference of cylinder? How do I find the circumference of a cylinder? If you know the cylinder’s radius: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That’s it; you found the circumference of the cylinder. What is the circumference of a 2 […]
What happens if 2 spiral galaxies collide?
What happens if 2 spiral galaxies collide? For example, two spiral galaxies can merge and form an elliptical galaxy. Galaxies are also composed of gas and dust. The gravitational pull of both colliding stars can interact with this materials, creating friction and shock waves that can ignite the formation of new stars. What will happen […]
How long do telescope mirrors last?
How long do telescope mirrors last? about three to five years Do microscopes use mirrors? The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object.
