In
cell-cell contact , signals pass through a cell junction from one cell to adjacent cells.
Membrane-bound signals bind to receptors on adjacent cells in the process of
paracrine signalling.
An example of
autocrine signalling is when cells release signals that affect themselves and nearby target cells.
In
synaptic signalling cells release signals that affect nearby target cells. Cells release signals that travel long distances to affect target cells during
endocrine signalling.

<h2>Proportion of mottled fish </h2>
Explanation:
- A predator can be defined as an organism that makes the other organisms die to obtain them as food. Prey is the living being which is typically inferior and killed by the predator. Adaptation is a change in the physiology, morphology and genetic makeup of the organism which makes it suitable for survival in an unfavorable environment. Natural selection is the differential survival and reproduction of the organisms which exhibit better traits over the others
- The population of the mottled fish is likely to increase due to natural selection. As the mottled fish color pattern match with that of the mottled background of the bottom of the lake. This will help the mottled fishes to camouflage the predator wading birds. These mottled fishes will remain undetected from the predator wading birds. The trait of the mottled pattern will be adapted by the light sandy brown fishes and the trait will be passed on the next generation as well. Hence, the proposition of the mottled fish will increase
- Hence, the right answer is "the proportion of mottled fish will increase over time"
I think it's convection currents or conduction or global warming
