Answer:
The correct answer is: b).
Explanation:
- Oil or solid fat is composed of long chains made up of hydrocarbons (fatty acids).
- The fatty acid can be:
- Saturated - in which all the carbon atoms in the long hydrocarbon chain are linked to each other by single bonds. As a result of this there is a tight packing between the fatty acid molecules which gives them a solid texture at room temperature.
- Unsaturated - in which there are one or more double or triple bonds in between carbon atoms in the long hydrocarbon chain. As a result of this kinks or bends develop in the fatty acid chain which results in generation of space or gap in between fatty acid chains. This gives the fatty acid the capability to move as a result of which they have a liquid texture at room temperature.
- Hydrogenation is a process by which the unsaturated fatty acids (oil) are converted to saturated fatty acid (margarine) by reducing the multiple bonds in between the carbon atoms with hydrogen.
- Hydrogenated oil has a higher melting point and so it is solid at room temperature.
- Hydrogenated oil can also cause clogging in the arteries as they cannot be easily broken down due to their increased stability.

<em>A natural disaster. </em>
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.
The answer to your question is where a cold ,dry air mass meets a warm ,moist air mass. Tornadoes usually form where a cold ,dry air mass meets a warm ,moist air warm.
