Answer:
adaptive radiation
Explanation:
In biology, adaptive radiation is the process where organisms quickly diversify from an ancestor species into a multitude of new forms, especially when a change in the environment makes new resources available, alters interactions or opens new environmental niches.
The answer would be evaporation
Answer:
Pangaea
Explanation:
When Laurentia and Gondawana, two minor supercontinents, collided, they created the Pangaea supercontinent.
The shoals are often more than 7 km long, 1.5 km wide and 30 metres deep and are clearly visible from spotter planes or from the surface. Sardines group together when they are threatened. This instinctual behaviour is a defence mechanism, as lone individuals are more likely to be eaten than large groups.
The shoaling habit includes all the popular, common fish that belong to the Characin family (tetras), Cyprinidae family (barbs and danios) and Melanotaeniidae family (rainbow fish). There are even some species of catfish and cichlids that shoal.
- Why do fish swim in shoals?
Many kinds of fish prefer to swim together in groups called shoals. ... Shoaling can help fish because there are more eyes for spotting danger from predators or for finding food. Predators also find it more difficult to target a single victim in a big, moving group.
Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
