How is oxygen maintained in the atmosphere? The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. in the atmosphere. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. How did we get oxygen in our […]
How does cyber security affect us?
How does cyber security affect us? Cyber threats are a big deal. Cyber attacks can cause electrical blackouts, failure of military equipment and breaches of national security secrets. They can result in the theft of valuable, sensitive data like medical records. They can disrupt phone and computer networks or paralyze systems, making data unavailable. Is […]
Which metal is used to make car bodies?
Which metal is used to make car bodies? The main materials used for making cars, parts and components, along with future trends, are steel, aluminum, magnesium, copper, plastics and carbon fibers. The prime reason for using steel in the body structure is its inherent capability to absorb impact energy in a crash situation. What is […]
Which two branching connect the trachea to the lungs?
Which two branching connect the trachea to the lungs? At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz). Which two branching tubes connect the trachea to the […]

When the surface is very smooth, the reflected highlight is easy to see. Why can’t you see your image on a concrete wall? Answer. Answer: You get diffuse […]
What is the resistance across A and B in the Fig 1 point?
What is the resistance across A and B in the Fig 1 point? ⟹ RAB=4+44×4=2Ω What is the total resistance between points A and point B given below circuit? Therefore, the total resistance in the circuit is 4+4+2=10 ohms. What is resistance between A and B? The three resistance of 20 ohm, 10 ohm and […]
How do the kidneys respond to acidosis?
How do the kidneys respond to acidosis? The kidneys respond to acid-base disturbances by modulating both renal acid excretion and renal bicarbonate excretion. These processes are coordinated to return the extracellular fluid pH, and thus blood pH, to normal following a derangement. What can the kidney do to compensate for acidosis? Renal compensation of respiratory […]
What causes the temp to decrease with height in the mesosphere?
What causes the temp to decrease with height in the mesosphere? Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere. Does temperature increase […]
