If the choice is true or false, the answer is true. Most of hominins were probably nearly as efficient at bipedal locomotion as humans. However, the bones of their pelvis were shorter from top to bottom than humans. This made their pelvis more stable for weight which supports standing upright or moving bipedially.
The answer is spicules. These
sharp-pointed structures are formed from calcium carbonate skeleton of
the organisms. They can also be formed from silica. They can be big (megascleres),
or microscopic (microscleres). Also dependent on the number of axis on the spicules, they are classified as monoaxon,
triaxon or polyaxon.
The answer is A. Sympatric
