Island isolation promotes allopatric speciation. Species are separated by the physical barrier which is in the ocean and islands are being isolated by each other by bodies of water.
There is no gene flow which occurs between the separated species. Living in the distinct island. The species get adopted by the island to the environment.
They then diverge as they separate species.
Answer:
The sodium-potassium pump cycle
The sodium-potassium pump transports sodium out of and potassium into the cell in a repeating cycle of conformational (shape) changes. In each cycle, three sodium ions exit the cell, while two potassium ions enter.
Explanation:
The complementary bases on the codon and anticodon are held together by hydrogen bonds, the same type of bonds that hold together the nucleotide in DNA. The ribosome only allows the tRNA to bind to the mRNA if it is carrying an amino acid. This takes place during the process of translation, where the bases of the anticodon form complementary base pairs with the bases of the codon by forming the appropriate hydrogen bonds.
