Symbioses are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called mutualisms.
In mutualism the relationship benefits the two organisms, the relationship can be within the species, between living things fro two different species among others. Example is the digestive bacteria and humans; Some food cannot be digested, therefore when these foods are consumed, the bacteria in the digestive tract feed on these foods, therefore the bacteria stays alive and humans gets helps in digestion.
Answer:
Possession of analogous (convergent) traits.
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
The term “analogous structures” comes from the root word “analogy,” which is a device in the English language where two different things on a basis of their similarities.
Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.
In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.
Protein, genes, chromosomes and DNA
Answer:
An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder.
