Arteries are the blood vessels which use elasticity to push blood further along the bloodstream. Correct answer: A They carry blood away from the heart to the rest of the body.
The middle layer of the arteries has smooth muscle and elastic fibers. The elastic fibers in the arteries expand to accommodate the blood and this way they help in maintaining a high-pressure gradient.

B) They have double bonds in the carbon chains of their fatty acids.
C) They are solid at room temperature.
D) They contain more hydrogen than saturated fats.
E) They have fewer fatty acid molecules per fat molecule.
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 answer is b! egocentrism
A water and sand table allows children to experiment with the concept of conservation, which is the understanding that the quantity of a substance remains the same even when its form or appearance changes.
A water and sand table is a great way to help children experiment with the concept of conservation. Conservation, in this context, refers to the understanding that the quantity or amount of a substance remains the same even when its form or appearance changes. For example, if a child pours water from a tall, thin cup into a short, wide container, they learn that the amount of water is still the same, even though its shape has changed, demonstrating the concept of conservation.
Similarly, using different containers for sand can help children understand that the amount of sand remains the same, even if the shape or container changes. These activities are a practical and interactive way to develop a child's cognitive skills and understanding of this important principle.
