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 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 […]

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. […]

Is there a state beyond plasma? If you bombard any atom with enough energy, you’ll kick the electrons off of it, creating an ionized plasma: the fourth state of matter. But there are two additional states of matter that exist: Bose-Einstein Condensates and Fermionic Condensates, the fifth and sixth states of matter. What is the […]

Does Matter have color? I hope it’s not too long. atoms (as opposed to molecules) do not have colors – they are clear except under special conditions.. you could not see the color of one atom or molecule – not because it is too small – but because the color of one atom would be […]

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 […]

How capacitance changes if the distance between the plate of a parallel plate capacitor is halved? Answer. The capacitance between plates will reduce to half of the original value. Thus, capacitance will be half of the original value. How does distance between plates affect capacitance? Larger plates provide greater capacity to store electric charge. Capacitance […]

How can I avoid paying taxes on severance? You can reduce your tax bill by directing your severance package to an IRA. Consider putting some of your severance into an HSA if you have a high-deductible health insurance plan. Ask your employer if the company can pay you out over two years. You can use […]

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 […]
