Answer:
The correct answer is vasoconstriction has occurred.
Thermal receptors present in the skin sense the cold around the surrounding and stimulates the sympathetic nervous system of the body.
It immediately causes vasoconstriction in the skin, legs, and arms.
Vasoconstriction prevents or decrease the heat loss from the body to the environment.
Decreased flow of blood to the skin and extremities turns the skin pale in color.
a hydrogen bond.

Photosynthesis is a process mechanism in plants<3
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:
