That would have to be the cell membrane an animal cell
Answer is- ask a question based on an observation
The correct option is C.
Specie specific signals are those signals which are limited to only one specie of animal. The specie usually use it to communicate with the members of the specie. Each signal normally have a specific meaning and will produce uniform response in its receivers.

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.
Diffusion happens in liquids and gases because their particles move randomly from place to place.
Diffusion is an important process for living things; it is how substances move in and out of cells.

<em><u>Three types of diffusion are distinguished, viz., molecular, Brownian, and turbulent. Molecular diffusion occurs in gases, liquids, and solids; both diffusion of molecules of extraneous substances (impurities) and self-diffusion are observed. Molecular diffusion occurs as a result of thermal motion of the molecules. It proceeds at a maximum rate in gases, at a lower rate in liquids, and at a still lower rate in solids—these differences being accounted for by the nature of thermal motion in these media.</u></em>
Answer:
Explanation:Antibodies work by recognising and sticking to specific proteins, such as those found on the surfaces of viruses and bacteria, in a highly specific way. When the body encounters a microbe for the first time, immune cells produce antibodies that specifically recognise proteins associated with that particular microbe.
