Answer:
B) They have double bonds in the carbon chains of their fatty acids.
Explanation:
Unsaturated fats have double bonds: They are characterized by one or more double bonds in the carbon chains of their fatty acids. These double bonds create kinks or bends in the carbon chain, preventing the molecules from packing tightly. This contrasts with saturated fats, which lack double bonds and have a straight carbon chain.
- Examples of unsaturated fats: Examples of unsaturated fats include vegetable oils, such as olive oil, canola oil, and sunflower oil, as well as fatty fish like salmon and trout. These fats tend to be liquid at room temperature, further supporting that they have double bonds and do not stack together tightly like saturated fats.
In summary, unsaturated fats are characterized by double bonds in their fatty acids' carbon chains, giving them a different structure and physical properties than saturated fats.
[option B] The true statement about unsaturated fats is that they have double bonds in the carbon chains of their fatty acids.
Unsaturated fats are a type of fat that have double bonds in the carbon chains of their fatty acids. These double bonds create kinks in the fatty acid chains, preventing the molecules from packing tightly together. As a result, unsaturated fats are usually liquid at room temperature. They are more commonly found in plant-based oils, such as olive oil and canola oil. In contrast, saturated fats have no double bonds in their fatty acid chains and are typically solid at room temperature. They are more common in animal-based products, such as butter and lard.

The single most effective way to prevent infections is hand washing. The two additional ways to control the spread of germs through the air are physical distancing and use of tissues.
• One of the best ways to keep oneself from getting sick is hand washing.
• It is mainly helpful at the time of cold and flu season when one is more around individuals who spread germs.
• It is important to take the time and wash the hands on regular basis as it is one of the best good hygiene practice.
• Apart from this, one can control the spread of germs by practicing physical distancing from members who are vulnerable to cold.
• And one should use tissue and should sneeze or cough into the arm, not the hand and should turn away from other individuals.
Thus, hand washing is one of the most effective way to prevent infections, and apart from this one should also practice physical distancing and use things like tissues in public.
