Matthew has discovered a new species of fish. during the summer months, the male fish separate themselves from the female fish and swim to cooler waters. during one summer, a volcano erupts and the molten rock forms a barrier preventing the male and female fish from reuniting. which of these best describes the long-term outlook for this new species of fish?
a. the species would not be affected by the barrier.
b. the male fish would begin to produce eggs and sperm.
c. the fish would develop legs and walk across the barrier.
d. the fish would become extinct as they would not be able to reproduce.

The correct answer is (d) The fish would become extinct as they would not be able to reproduce.

In this situation the male and female species across barrier will extinct as they would not be able to reproduce because of the barrier. It is physiologically not possible for the fishes to swim across the barrier, and moreover a male fish cannot produce male and female gamete by its own. They will extinct as they would not be able to reproduce.

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.
