Which of the following is a correct comparison between mitosis and meiosis? So, the correct answer is ‘Meiosis II resembles mitosis when sister chromatids split’ Which is the correct order of these mitosis events? Stages of mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis typically overlaps with anaphase and/or telophase. You can remember the order of the […]
What is the main form of energy?
What is the main form of energy? After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object. What is energy transferred from? Energy […]
Does the melting point increase across a period?
Does the melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from […]
What causes a comet to move?
What causes a comet to move? Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. How do I track comets? How to See Comet […]
Is Iron bad for copper pipes?
Is Iron bad for copper pipes? On cold-water piping, pitting and corrosion is often caused by an excess amount of flux residue. Iron deposits from a rusty water heater can also corrode copper pipes. What pH level is toxic? Toxic effects on survival, motility, and growth decreased with increasing pH. From pH 6.9 to 9.0, […]
What are the three components of sound?
What are the three components of sound? It is received wisdom within the sonic branding business, that there are three different types, or elements, of sound.

What are the three layers of soil profile?
What are the three layers of soil profile? The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics. These features of the layer of soil play a very important role in determining the use of the soil. Soil that has developed three layers, is mature soil. […]
What is crystallization for Class 7th?
What is crystallization for Class 7th? Crystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. The process is employed in the separation of pure common salt from the impure common salt obtained from sea. What is the principle of […]
What is the major difference between simmering and poaching?
What is the major difference between simmering and poaching? Poaching is a technique typically used for delicate foods including eggs, fish and fruits. In order to poach food effectively, it must be completely submerged in water. Simmering requires the temperature of the liquid to be between 185 to 200 degrees. What food can be boiled? […]
