On the Galápagos Islands, the finches that Darwin studied tended to have either small beaks or large beaks. The smaller beaks ar

e best at eating soft seeds but are ineffective at cracking large seeds. The larger beaks are best at cracking hard seeds. Beaks of intermediate size are inefficient for either seed type. Which result of natural selection is at work in this example?
A. stabilizing selectionB. directional selectionC. disruptive selectionD. individual selectionE. unnatural selection

Answer:

The correct answer is option C. "disruptive selection".

Explanation:

Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.

Why does water move through a membrane?
AnnZ [28]

Answer:

The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.

Explanation:

The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water.  In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
