Yes, the cell membrane regulates what enters the cell and leaves the cell. The cell membrane is a fluid mosaic consisting of a phospholipid bilayer and integral and peripheral proteins. The proteins of the membrane serve many purposes: transport, receptors, etc. The cell membrane is amphipathic, meaning is has hydrophilic and hydrophobic regions.
The proprioceptors are the sensors in the limbs, which give information regarding the muscle length, joint angle, and muscle tension that is combined to provide knowledge regarding the alignment of the limb in space. The muscle spindle is one of the kinds of proprioceptor, which gives information regarding the changes in the length of the muscle.
On the other hand, a nociceptor refers to a sensory neuron, which reacts towards the potentially damaging or destructing stimuli by conducting probable danger signals towards the brain and the spinal cord.
Proprioceptors are to reflex actions as nociceptors are to pain perception.
The answer is B. The higher the concentration of substrate, the FASTER a reaction happens (since there are more opportunities for molecules to collide in a way that favours the reaction), so B is an incorrect statement.
The other three options describe correct features of catalysts and/or enzymes (which are considered “biological catalysts”).
Answer:EVERY OBJECT REMAIN AT THE STATE OF REST IN A UNIFORM MOTION UNLESS AN EXTERNAL FORCE ACTED UPON IT
