How did the mechanical legs using to building robots reassemble the walking motions how are they different

One disadvantage of cloning is allows the continuation of species facing extinction new organisms are often sickly and do not live long lives scientists can study why nerve cells don't multiply scientists can study how organisms grow and reproduce

A submarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. What is the approximate pressure (water plus atmospheric) at this depth? (Recall that the density of seawater is 1025 kg/m3 g = 9.
