What causes parallel evolution? Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition. Frequently this is the situation in more closely related lineages, where several species respond to similar challenges in a similar way. What is the difference between convergent and parallel evolution? Strictly speaking, convergent evolution occurs when […]

Can you make a cloud?
Can you make a cloud? In this activity, you can make your own cloud to see for yourself! Clouds form from the condensation or freezing of water vapor. Condensation is the process of a gas changing into a liquid. Water vapor in the atmosphere cools and condenses on particles in the air, creating a cloud. […]
Is death a characteristic of life?
Is death a characteristic of life? All living things have common traits, irrespective of plants and animals. Living beings can be broadly classified into plants and animals. They both have common characteristics, and follow a universal circle of life that includes birth, reproduction, and death. Do all living things move independently? All living things move […]
What is the relationship between membrane potential and resting potential?
What is the relationship between membrane potential and resting potential? If the membrane potential becomes more positive than it is at the resting potential, the membrane is said to be depolarized. If the membrane potential becomes more negative than it is at the resting potential, the membrane is said to be hyperpolarized. How did the […]
What is the formula for work done by friction?
What is the formula for work done by friction? Friction does negative work. Example 10: In Example 9, the work done by force of friction is -112,000J. Use the work formula to calculate the force applied by friction if brakes were used within a distance of 56m. Solution: Using Work formula: W = Fk x […]
Why is the mathematical relationship among the amount volume?
Why is the mathematical relationship among the amount volume? Why is the mathematical relationship among the amount, volume, temperature, and pressure of a gas sample called the ideal gas law? It works best for ideal gases, i.e. minimum attraction between particles and the particles are extremely small. The numerical value depends on what units are […]
What is the flow of electrons called?
What is the flow of electrons called? Electric current is flow of electrons in a conductor. The force required to make current flow through a conductor is called voltage and potential is the other term of voltage. For example, the first element has more positive charges, so it has higher potential. Do electrons flow with […]
Which of the following is a surface phenomenon?
Which of the following is a surface phenomenon? When the temperature rises, then the process of evaporation occurs, as a result of which the molecules are easily disintegrated at the surface. It is due to this, the process of evaporation is commonly considered as a surface phenomenon. Why is melting a surface phenomenon? The kinetic […]
Can two elements have same number of neutrons?
Can two elements have same number of neutrons? Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number. Can 2 elements have the same atomic mass? Different isotopes of the same element […]
