The main component of the cell membrane is a phospholipid bi-layer or sandwich. The heads (the phospho part) are polar while the tails (the lipid part) are non-polar.
<h2>Resilience of bone</h2>
Explanation:
The resilience of bone comes from sacrificial bonds in or between collagen molecules
- Three major functions of bones includes
Providing structural support to the body
Providing protection to vital organs
Providing an environment for marrow (where blood cells are produced)
- There are two types of tissues which bones are composed of:
A hard outer layer called cortical bone which is strong, compact,dense and tough
A spongy inner layer called trabecular bone,this network of trabeculae is lighter and less dense than compact bone as a storage area for minerals (such as calcium)
- Bone is also consists of:
Bone forming cells (osteoblasts and osteocytes)
Bone resorbing cells (osteoclasts)
Non mineral matrix of collagen and noncollagenous proteins (osteoid)
Inorganic mineral salts deposited within the matrix
- Bone ends up being a good example of resilience because it is not static like it is perceived to be
The cautions that can be given to the friend include the following:
Eating foods from different sources is very advantageous because it ensures that one gets all the necessary food nutrients that are needed for proper growth and development. Getting the necessary food nutrients on the other hand will boost one's immunity and enable one to develop resistance to diseases. Restricting one's food to a limited type of food is very bad and can have fatal consequences.
