a. receptor-mediated homeostasis
b. autoregulation
c. positive feedback
d. extrinsic regulation

Answer is D. Extrinsic regulation.

Explanation:

Extrinsic regulation is a type of regulation involving the activity of the nervous system or the endocrine system. Their activities bring about responses environmental changes.

The nervous system work by sending electrical signal while the endocrine system work by sending chemical signal, to adjust the activities of many systems in the body to the changes in the environment.

Extrinsic control involves the activity of outside organ to control another organ in homeostasis, while intrinsic control involves the activity of the actual organ to maintain homeostasis in itself.

Note that, homeostasis is the ability to maintain internal temperature to complement the changes in the environment.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
