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

stellarik [79]

Answer:

25 years

Explanation:

Ossification is the process of bone tissue formation. Osteoblasts are responsible for the process of ossification. It begins when the fetus is three months old and goes on till 25 years of age. Upper limbs get ossified first, followed by lower limbs, sternum and vertebrae.

There are two types of ossification processes. When bone is directly developed using the primitive connective tissue (mesenchyme) it is called as  intramembranous ossification, while in endochondral ossification cartilage is used as a precursor.
