How does a sperm whales body adjust to hydrostatic pressure?

Explanation:

Sperm whales can dive down to 2000m which is 200 atmospheres in pressure on top of its body. Whales access reserve oxygen in its blood and muscles – not from the air in its lungs. Whales have more than 2x the hemoglobin in their blood as humans have and 10x the myoglobin. A SPERM WHALE can dive down more than 2,000 meters and can stay submerged for up to an hour. Some sea creatures exploit great depths.

Spermaceti and Diving Capabilities :

One common theory is that the fluid—which hardens to wax when cold—helps the whale alter its buoyancy so it can dive deep and rise again. Sperm whales are known to dive as deep as 3,280 feet in search of squid to eat.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
