How do water molecules move in and out of cells? Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of […]

What type of bond would form between CL and C?
What type of bond would form between CL and C? Each atom in HCl requires one more electron to form an inert gas electron configuration. Chlorine has a higher electronegativity than hydrogen, but the chlorine atom’s attraction for electrons is not sufficient to remove an electron from hydrogen….Polar Covalent Bonds. Structural Unit1 Bond Moments (D) […]
What is importance of nucleus?
What is importance of nucleus? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm. What is Nucleus explain? […]
What is the difference between batteries in series and batteries in parallel?
What is the difference between batteries in series and batteries in parallel? In a series connection, batteries of like voltage and amp-hour capacity are connected to increase the voltage of the overall assembly. In a parallel connection, batteries of like voltages and capacities are connected to increase the capacity of the overall assembly. Why are […]
Is heat added or removed in condensation?
Is heat added or removed in condensation? A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses. What happens when a solid is heated Class 9? […]
What happens when a material is deformed Why?
What happens when a material is deformed Why? When a sufficient load is applied to a metal or other structural material, it will cause the material to change shape. This change in shape is called deformation. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its […]
Which is an empirical formula?
Which is an empirical formula? An Empirical formula is the chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the actual numbers or arrangement of atoms. This would be the lowest whole number ratio of the elements in the compound. What is the empirical formula […]
