The evolution of sexual reproduction is a great puzzle in modern evolutionary biology. Many groups of eukaryotic organisms, especially most animals and plants, reproduce sexually. The evolution of sex between two organisms of the same species contains two related but different themes: its origin and its maintenance. However, since hypotheses for the origin of sex are difficult to test experimentally, most of the current work has focused on the maintenance of sexual reproduction. Biologists, including W. D. Hamilton, Alexei Kondrashov, and George C. Williams, have proposed various explanations for how sexual reproduction is maintained in a large set of different living things.

kolbaska11 [484]

Answer:

Option 1, a charged end and a noncharged end

Explanation:

Complete question

If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____

  1.  a charged end and a noncharged end
  2.  three fatty acid molecules, all pointing in different directions
  3.  two fatty acid molecules pointing in different directions
  4.  both a saturated fatty acid and an unsaturated fatty acid
  5.  two charged ends

Solution

The structure of phospholipids consists of the following groups and molecules –  

a) A glycerol molecule  

b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature

c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.  

When the phospholipids are placed in  water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.

Hence, option 1 is correct
