Do lizards lay fertilized eggs? Most reptiles reproduce sexually and have internal fertilization. Males have one or two penises that pass sperm from their cloaca to the cloaca of a female. Fertilization occurs within the cloaca, and fertilized eggs leave the female’s body through the opening in the cloaca. What animals lay unfertilised eggs? Oviparity […]

What is the relation between temperature and kinetic energy? Temperature is directly proportional to the average translational kinetic energy of molecules in an ideal gas. How do speed of molecules kinetic energy and temperature of matter affect each other? If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. […]

How did the Challenger crew actually die? The 37-year-old was to become the first teacher in space after being selected from more than 11,000 applicants to the NASA programme – but just 73 seconds into its flight, Challenger erupted in a ball of flame, killing all seven of the crew on board. Did they recover […]

What is the first step of hearing? Step one: The outer part of the ear captures a sound wave and funnels it through the ear canal, where it strikes the tympanic membrane (or outer layer of the eardrum). Step two: The sound wave causes the eardrum and the three small ossicles bones within the middle […]

What is not a crosscutting concept? In brief, a concept is crosscutting if it communicates a scientific way of thinking about a subject, and it applies to many different disciplines of science and engineering. A concept is not crosscutting if it does not communicate a scientific way of thinking or if it only applies to […]

How do you test if a solution is saturated? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of […]

Does hot water have a higher entropy? The entropy increases whenever heat flows from a hot object to a cold object. It increases when ice melts, water is heated, water boils, water evaporates. The entropy increases when a gas flows from a container under high pressure into a region of lower pressure. Does cold or […]

What energy is lost when a ball bounces? Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball’s energy is converted into heat. As no energy is added to the ball, the ball bounces […]

What does V x t mean in physics? v– = x. t. “Average velocity is the distance traveled divided by the elapsed time.” What does V mean in physics? volt What does V not mean in physics? Since the highest order is 1, it’s more correct to call it a linear function. The symbol v0 […]

Is Crest and amplitude the same? The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. How do […]
