If you do not perceive a color change, or the emission of light or heat, it is still possible a chemical reaction has taken place.

A chemical change involves a change in the composition of a substance. It leads to the rearrangement of atoms and formation of a new substance.

Some cues may help us to know when a chemical change has taken place such as;

  • Change in color
  • Formation of a solid
  • Evolution of heat
  • Evolution of a gas

It is possible for a chemical change to occur without noticing these cues. For instance, two colorless solutions may react with each other and the product of the reaction remains colorless.

In this case, there is no physical cue signifying that a chemical change has taken place even though it actually happened.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptat
expeople1 [14]

Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.  

In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.  

These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.

What happens when lakes are acidified?
Dima020 [189]
Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, crayfish and clam populations are the first to disappear, then various types of fish. Many types of plankton-minute organisms that form the basis of the lake's food chain-are also affected. As fish stocks dwindle, so do populations of loons and other water birds that feed on them. The lakes, however, do not become totally dead. Some life forms actually benefit from the increased acidity. Lake-bottom plants and mosses, for instance, thrive in acid lakes. So do blackfly larvae.
