The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>
Explanation:
The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).
The PNS is divided into somatic and autonomic nervous systems.
The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.
The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.

Answer:
The correct answer is D. involves proteins in plasma membranes.
Explanation:
Animal cells have several types of proteins embedded in their cell membrane. These proteins play an important role in the transport of molecules, cell recognition, and cell communication.
Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.
These proteins are important for proper growth and development of the cell. Therefore the correct answer is D. involves proteins in plasma membranes.
Answer:
The percentage of caterpillars original energy available to the hawk is = 0.6%.
Explanation:
the answer above is given by; 24 kcal/4000 kcal x 100
Caterpillars are the larval stage of members of the order Lepidoptera. As with most common names, the application of the word is arbitrary, since the larvae of sawflies are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes.
Hawks are a group of medium-sized diurnal birds of prey of the family Accipitridae. Hawks are widely distributed and vary greatly in size. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks and others. This subfamily are mainly woodland birds with long tails and high visual acuity.
