Answer:
The most common position for an double bond in an unsaturated fatty acid is delta 9 (Δ⁹)
Explanation:
Unsaturated fatty acids are carboxylic acids which contains one or more double bonds. The chain length as well as the number of double bonds is written separated by a colon. The positions of the double bonds are specified starting from the carboxyl carbon, numbered as 1, by superscript numbers following a delta (Δ). For example, an 18-carbon fatty acid containing a single double bond between carbon number 9 and 10 is written as 18:1(Δ⁹).
In most monounsaturated fatty acids, the double bond is between C-9 and C-10 (Δ⁹), and the other double bonds of polyunsaturated fatty acids are generally Δ¹² and Δ¹⁵. This positioning is due to the nature of the biosynthesis of fatty acids. In the mammalian hepatocytes, double bonds are introduced easily into fatty acids at the Δ⁹ position, but cannot introduce additional double bonds between C-10 and the methyl-terminal end. However, plants are able to introduce these additional double bonds at the Δ¹² and Δ¹⁵ positions.
It's sunny in new york, but it is cool, we will expect to find lizard under a rock or in a hole in the ground.
<h3>Why lizards are not comfortable in cold?</h3>
Lizards are not comfortable in the cold season as they are cold blooded animal, so their body will gets slow in the winter season.
During the winter season or in the cool weather, lizards will go to the places where they faces less cooling. And these places be like inside the rocks, under a hole, under the ground, in the trunks of trees, etc.
Hence, options (1) and (4) are correct.

Dalton's theory explained that all matter constitutes of atoms that are indivisible and indestructible. They combine in definite ratios and posses definite masses. He considered atom to be the smallest particles that the matter is composed of. He basically explained about the chemical properties of matter.
After many more researches, it was explained that atom is not the smallest particle that the matter is composed of but it contains many subatomic particles like protons, neutrons and electrons that the matter is made of. Dalton could not explain about the nuclear property of atom.
The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO
Yes it’s a real substance and yes it should be banned because it kills people without warning.It has no taste,smell,and you can’t see it.
