Answer:
The mechanism is natural selection.
Explanation:
Natural selection is the mechanism that these air-breathing fishes have gone through to survive. This mechanism allows species to survive and reproduce due to differences in the phenotypes of every individual in the specie, throughout the time the heritable traits that every individual inherits changes according to the environment and the characteristics of its ancestors.
A ribosome<span> is a cell organelle. ... </span>Ribosomes<span> are found 'free' in the </span>cytoplasm<span> or bound to the endoplasmic reticulum (ER) to form rough ER.

Explanation:
In most animals, the <u>diploid</u> state of the life cycle is much larger than the <u>haploid</u> state.
The multicellular diploid stage is the most evident life stage in a diploid-dominant life cycle, and the only haploid cells are the gametes. Most animals, including humans, have this kind of life cycle. It is much larger than the haploid life cycle because of the complexity due to diploid stages.
The multicellular (or occasionally unicellular) haploid stage is the most visible life stage and is frequently multicellular in a haploid-dominant life cycle. The only diploid cell in this kind of life cycle is the single-celled zygote. This kind of life cycle is found in some algae and fungi.
Meiosis, which produces haploid cells from diploid ones in all sexually reproducing species, and fertilisation are two examples of fundamental life cycle characteristics that all sexually reproducing species share (the fusion of haploid gametes to form a diploid cell called the zygote).
