Walking upright.

You can make a case for all of them, but for three of them indirectly.

But the answer, I think, is walking upright.

You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.

Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.

I hope that helps.

What’s the answer to this earth science question?

Answer:

option 1

Explanation:

The warm waters of the Gulf Stream run along the east coast of the United States. This provides an environment which is conducive to the development of hurricanes. The basics of the formation of a hurricane are as follows. Winds start blowing in a circular motion. This causes hot, moist air to rise. Clouds are formed and the winds start blowing faster and faster. This forms a low-pressure zone. The surrounding high-pressure zones pull the hurricane towards them. As the hurricane moves, it either picks up speed or decreases its speed and intensity.

Large molecules, such as glucose, that cannot cross the lipid bilayer can still move across the membrane through a type of passi

harkovskaia [24]

Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.
