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.
Answer:
The dorsolateral dermal plicae of the leopard frog are two pale, thickened bands of the dorsal skin extending posteriorly from each eye to the urostyle prominence While they are normally found in all areas of trunk skin, the largest ones are in the plicae
Explanation:
The term <u>Ataxia</u> means the lack of muscle coordination during voluntary movement.
- Poor muscle control that results in awkward voluntary movements is known as ataxia.
- It might make it difficult to move your eyes, speak, or walk steadily. It might also make it hard to coordinate your hands.
- Ataxia is typically caused by injury to the cerebellum, which regulates muscular coordination, or its connections.
- Ataxia is typically brought on by damage to the cerebellum, a region of the brain, although it can also be brought on by injury to the spinal cord or other nerves.
- The spinal cord, which extends the length of the spine and connects the brain to every other part of the body, is a lengthy bundle of nerves.
