When you rub the two balloons against your hair what will happen if you bring the two balloons near each other? Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Like charges repel (the two balloons, once charged, will move […]
What is the term for the angle at which light undergoes total internal reflection?
What is the term for the angle at which light undergoes total internal reflection? This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. For any angle of incidence greater than the critical angle, light will undergo total internal reflection. Which of […]
How does the 1st and 2nd law of thermodynamics apply to biological systems?
How does the 1st and 2nd law of thermodynamics apply to biological systems? Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy […]

What is difference between PCT and DCT?
What is difference between PCT and DCT? PCT occurs after the Bowman’s capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT. The main difference between PCT and DCT is that PCT is the function of each part in the nephron. Which is […]

Can a population increase even though its growth rate is decreasing?
Can a population increase even though its growth rate is decreasing? Not only the population itself was growing, but also the doubling time was decreasing, which basically means that growth itself was growing. This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in […]
