Answer:
Lipid A, present as part of a Lipopolysaccharide complex in the outer membrane of gram negative bacteria cell walls, should be the answer, but it does not appear in the options included. As option C states “Amino terminal triglyceride”, and triglycerides are lipids, then we could explore this option. However, nothing is said about lipoproteins linked to Lipid A (that acts as an endotoxin) to mention carboxyl- or amino- terminals (options A and C), so I would consider the core oligosaccharide option as more probable (see below*).
Explanation:
Murein and peptidoglycan are names used to refer bacterial cell walls main component. This complex is mainly composed by disaccharide units composed of alterning N-acetyl-muramic acid (that contains the same structure of N-acetylglucosamine, plus a tetrapeptide) and N-acetyl-glucosamine, which form the backbone of the wall. These are responsible for the strength and shape of the cell. In Gram negative bacteria, an outer layer called outer membrane, as it contains an important amount of lipids, linked to other molecules, is also present. There, Lipid A is associated to a core oligosaccharide, and subsequently to the Antigen O (polysaccharide) forming Liposaccharides, wich stabilize and give strength to gram negative cell walls.
*Lipid A is the main responsible molecule for toxicity in these cell walls. As in question answer options, is included in B option “Oligosaccharide core”, which is closely linked to Lipid A, it could be the option to choose. Moreover, oligo saccharides are involved in toxicity responses in several microorganisms

Answer:
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!
I hope this helps you!
Have a great day
<span>100 g of KClO3 @ 122.55 g/mol = 0.816 moles of KClO3
by the reaction
2 KClO3 --> 2 KCl & 3 O2
0.816 moles of KClO3 @ 3 moles O2 / 2 moles KClO3 = 1.224 moles of O2 can be made
using molar mass
1.224 moles of O2 @ 32.0 g/mol =
39.2 grams of O2 can be made</span>
