Explanation:
Endocrine disrupters are chemicals that alters or interrupts the normal functioning of the endocrine system that consists of several glands that produce hormones responsible for various functions such as metabolism, reproduction, growth, etc. When this interferes with the endocrine system, it can bring about many undesirable consequences, one of which is low testosterone levels as reported in the Alligators in Florida lake that is polluted by high levels of dioxins.

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.
