Dog breeding is an example of Associative mating.
Answer;
The similarity between gills and lungs is that both are sites for gaseous exchange in living organisms.
Explanation;
Gills is a site for gaseous exchange in fishes amphibians at some stage in life; while the lungs is a site of gaseous exchange in mammals and other organisms such as reptiles.
They both serve to bring in oxygen in the living things body and the eliminate carbon dioxide from the body; process of gaseous exchange.
However, they differ in a number of ways; for example, lungs are internal while gills are external , lungs are developed to breath in oxygen from the air, while gills are developed to get oxygen from water.
The answer is the central dogma of molecular biology.
The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Simply, DNA codes for RNA and RNA codes for proteins. The central dogma was first stated by Crick in 1956.

<span>The type of biological interaction when bears and coyotes may fight over the prey is called competition. Competition is an interaction between the members of the same or different species in which they compete for resources. If resources, such as food, are limited and several species depend on these resources, they must compete to win more resources for themselves.</span>
