The cell is the basic structural and functional unit of life. All living organisms are composed of one or more cells.
Motion of an object along a circular path at constant speed. Example: a fan blade tip or a satellite orbiting Earth.
Dissolve in water, filter to remove sand, then evaporate the filtrate to obtain pure salt crystals.
An object remains at rest or uniform motion unless acted by an external unbalanced force. Also called law of inertia.
Work is the transfer of energy. When work is done on an object, energy is transferred to it, changing its state.
Electrons (negative), protons (positive), and neutrons (neutral). Protons and neutrons reside in the nucleus.
It equals the number of protons in the nucleus of one atom. It uniquely identifies the element.
Asexual involves one parent and no gamete fusion. Sexual involves two parents and fusion of male and female gametes.
Cell structure, body organization, mode of nutrition, reproduction, and phylogenetic relationships are key criteria.
Living organisms (biosphere) obtain minerals and nutrients from the Earth’s crust (lithosphere) and anchor roots or burrow into it.
