Each double bond in carbon dioxide represents two pairs of electrons which are shared between the carbon and oxygen atoms.
<h3>What is an Electron?</h3>
This refers to a subatomic particle which has a negative charge and is involved in chemical reactions.
Each double bond in carbon dioxide represents two pairs of electrons which are shared between the carbon and oxygen atoms so as to enable them achieve an octet configuration.

<h3><u>Answer;</u></h3>
The permeability of the membrane
<h3><u>Explanation</u>;</h3>
- The fluidity and the permeability of cell membrane must be maintained within a certain range for the cell to function properly.
- The permeability of cell membrane depends on a number of factors, among them is the degree of saturation of fatty acids tails making up phospholipids.
- Phospholipid tails can be saturated or unsaturated. Saturated tails have no double bonds and as a result have straight, unkinked tails, while unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
- Interactions between tails are maximized in the case of saturated tails, thus decreasing membrane fluidity and permeability, while unsaturated tails increases membrane fluidity.
Animal’s and Plant's circulatory system:
1. Animals have circulatory system for the transport of nutrients and waste and plants have vascular system for the exchange of gases and nutrient.
2. Animals have specialized circulatory systems like.ARTERIES,VEINS and CAPILLARIES.
3. IN PLANTS, they have bidirectional transport system…like FOOD prepared though PHOTOSYNTHESIS is transported to different parts of plant body through phloem..while minerals and water intake by roots r transported by xylem..
4. ANIMALS circulatory system works on presence of amount of blood.
5. PLANTS circulatory system works on availability OF resources.
