It is always done on purpose.
So I did a punnet square and my results are XcXc, XXc, XcY, and XY. so yes there is possibility they could have a colorblind female (XcXc).
The skeletal movements of muscles are mostly voluntary. That is why skeletal muscle is also called voluntary muscle. Their action is normally controlled by an individual's will.
Answer:
proprioceptor
Explanation:
Proprioceptors are the receptor located in a joint, muscle, or tendon. These receptors are concerned with locomotion, posture, and muscle tone. These receptors respond to internal stimuli only and are present in a specific location in the body. For example, the tendon organ is a proprioceptor present in the tendon. The function of the tendon organ is to monitor the muscle tension and to prevent its tearing. These receptors also help smooth start and termination of muscle contraction.
Proprioceptors are the mechanoreceptors that regulate the body’s equilibrium and posture by their role in reflex actions that maintain muscle tone. They sense the position of limbs by detecting the degree of muscle relaxation, the stretch of tendons, and ligament movements.
Invertebrate, b/c it doesn't have a spine of any kind
