One important adaptation that separated us from other animals in our evolutionary trajectory is _________.

malfutka [58]

We can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

<h3>What is bipedalism?</h3>

Bipedalism was the adaptation of early human ancestors to abandon movement on all fours and begin to walk up-right. This was a vastly important adaptation as it provided the early humans with freed hands, allowing for many other uses such as tools and social cues.

Therefore, we can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

The structure of the cell membrane allows it to be selectively permeable. What is the name for the larger, brown structure in th

Anika [276]

Explanation:

B) protein channel

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules which are typically prevented from moving across the membrane.
Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion
