What are the most likely effects of the range expansion of the sea urchin?

The movement of the sea urchins into habitats already occupied by black-lipped abalone will most likely cause
in the level of interspecific competition for resources. As a result of the range expansion of the sea urchins, the population size of black-lipped abalone

Explanation:

already occupied by black-lipped abalone will most likely cause in the level of interspecific competition for resources. As a result of the range expansion of the sea urchins, the population size of black-lipped abalone

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
