The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
Answer:
Cervical vertebrae
Explanation:
The cervical vertebrae are the vertebrae present in the neck region. All cervical vertebrae are characterized by the presence of three foramina. One is the vertebral foramen and the rest two are called transverse foramina. Each transverse process of each cervical vertebrae contains a transverse foramen. The vertebral artery and the related vein and nerve fibers pass through the transverse foramina. Among the all cervical vertebrae, the transverse processes and transverse foramina of the atlas are relatively larger.
