Yellowfin tuna, or thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. they typically school under objects such as boats or patches of driftwood for protection from predators. schooling under these structures also provides yellowfin tuna with easy access to a food source such as smaller herbivorous fish that may be foraging for food around the structures. which trophic level does yellowfin tuna fill in a food chain? we

A trophic level of an organism shows its position in a food chain:

1. Producers, such as plants and algae, produce their own food and thus are the base of every food chain.

2. Primary consumers eat producers. They are herbivores that eat plants.

3. Secondary consumers eat primary consumers. They eat herbivores, so they are carnivores or omnivores.. 

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
