What were the major contributions of the h. m.s. challenger to the study of oceanography? how did its expedition contribute to future studies of the ocean?

The Challenger was a corvette class ship, a military vessel that traveled under sail but had auxiliary steam power, which helped to stabilize the vessel during sampling. Sixteen of the ships 18 guns were removed, and in their place were installed miles of sampling rope and wire, thermometers, water bottles, and bottom samplers.

C. Wyville Thomson led the expedition but died of exhaustion from the journey, which ended on May 24, 1876. The Challenger had zig-zagged around the globe and had visited every continent, including Antarctica.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
