Ammonia, because it’s a polar molecule, will get attracted to the hydrophilic end while the vegetable oil (non-polar) will interact with the hydrophilic end. Both, therefore have the capacity to dissolve in soap due to the amphipathic properties of soap.
Explanation:
Soap can be categorized as having amphipathic properties. Soap can be composed of fatty-acid chains co-joined with sodium/potassium ions. The fatty acid chains act as hydrophobic ends while the fatty acid acts as the hydrophilic end. This is why soap is a good washing agent The hydrophilic end attached to the ‘dirt’ that needs to be washed away, while the hydrophilic end interacts with the water molecules. Rinsing then washes away the soap including the ‘dirt’.

Answer: A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. ... In the food chain, energy is transferred from one living organism through another in the form of food. In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass rightarrow→right arrow cow rightarrow→right arrow human. But what if you had lettuce on your hamburger? In that case, you're also part of a food chain that looks like this: lettuce rightarrow→right arrow human

Answer:
Gene mutation
Explanation:
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block base pair to a large segment of a chromosome that includes multiple genes
