The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.
An organ or tissue may be better able to resist damage from hypoperfusion if the: body's temperature is considerably less than 98.6°F (37.0°C)
<h3>What is hypoperfusion?</h3>
- A word used to denote "a decreased amount of blood flow" is hypoperfusion. We can refer to ischemia that arises as "hypoperfusion" when there is insufficient blood flow.
- Low blood pressure, heart failure, or blood volume loss are some of the causes of hypoperfusion. Lightheadedness, dizziness, headaches, nausea, exhaustion, and shortness of breath are typical symptoms that are made worse by being upright and made better by lying down.
- Thromboemboli are encouraged to form by hypoperfusion. Severe occlusive lesions result in hypoperfusion, which alters the quantity and turbulence of blood flow and encourages the development of both white and red thrombi, which are the building blocks of emboli.

Answer:
Carbohydrates may be defined as the polymers of the sugars and one of the most important biomolecule of the living organisms. Carbohydrates plays an important structural and functional role.
Carbohydrates are always present on the exoplasmic surface of the plasma membrane. The are present in the association with the proteins and lipids as glycoproteins and glycolipids. These carbohydrates acts as the signaling molecule that display information on cell surface.
