Answer:
The term secretion refers to the cell that releases a substance into the extracellular space.
Explanation:
When a cell or organ or gland produce and secretes substance in to extracellular space,this biochemical process is called as secretion.
The secretory products may be hormone, enzymes etc.
This process facilitates the movement of material from one place to another place.
For example, Pituitary gland produce and release prolactin hormone that induces breast cells to produce lactation during sucking process done by baby.
Pituitary gland also secrete different hormones that acts on different glands like adrenal, testes, ovary, thyroid gland etc that in turn produce different hormones like adrenaline,testosterone,estrogen,progesterone, TSH,T3, hormone etc.
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).

I processes that transfer energy over Earth's surface are:
1) Conduction
2) Convection
3) Radiation
4) Latent Heat
Conduction is the transfer of heat from a warmer object to a cooler object through molecular interaction. As the Sun heats the ground, energy from the heated ground is transferred to the atmosphere by conduction.
Convection is the transfer of heat by mass movement of a fluid. Convection appears mostly in liquid and gases because they are free to move around. Heat is transferred upward and outward, away from the heat source, while cooler air is brought to replace the rising air.
Radiation is the final process of heat transfer. The energy received from the Sun, radiation, are absorbed by all objects that in turn radiates some of the energy back to its surroundings in a weaker form of energy called long wave radiation such as heat.
Later heat, also known as phase change, is the heat required to change phases. Example of phase change is water transforms from gas to liquid or solid or vice versa. For water to transform from liquid to gas, latent heat from the surrounding atmosphere is needed. In evaporation, water takes heat from the surrounding air in order to evaporated and become gas.
