the r group or side chain of the amino acid glutamic acid is hydrophilic. The R group of the amino acid valine is hydrophobic. w
boyakko [2]

Answer:

You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.

This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.

Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

Physical differences in beaks of birds would develop as a result of different environmental changes.

<h3>What is Evolution?</h3>

This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.

This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.

The "rod-cone break" in the dark adaptation curve occurs after about ____ in the dark.
emmainna [20.7K]
The correct answer is "<span>7 minutes".

The Rod-Cone-Break is considered to be a d</span>ark environment adaptation function in the eye, wherein for an estimated time of the first ten minutes in the dark, the cones<span> needs less light to reach a threshold response than do the </span>rods<span>. Thereafter, the </span>rods<span> need less light. The point at which the </span>rods<span> become more sensitive is called the </span>rod-cone break<span>.</span>
