How do plant cells work together to maintain homeostasis? Homeostasis literally means same state, the desired state for a healthy plant. Plant cells have rigid walls that contain organs that regulate plant health and growth. Among the plant cell organs are the vacuoles, the largest and main mechanisms for maintaining homeostasis, and chloroplasts, which produce […]

What is the sign of image distance of a concave mirror? When image […]
What is Stokes law and its derivation?
What is Stokes law and its derivation? The law is derived considering the forces acting on a particular particle as it sinks through the liquid column under the influence of gravity. The force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of the sphere, and […]

What are the 3 right hand rules?
What are the 3 right hand rules? These are for (1) long, straight wires, (2) free moving charges in magnetic fields, and (3) the solenoid rule – which are loops of current. Calling these “rules” is the right name. What is the application of right hand thumb rule? The right-hand thumb rules can be used […]
How can you tell if two rectangles are similar?
How can you tell if two rectangles are similar? For two rectangles to be similar, their sides have to be proportional (form equal ratios). The ratio of the two longer sides should equal the ratio of the two shorter sides. How do you know if two parallelograms are similar? Find a pair of possible adjacent […]
