If we want to tip 19% or 0.19 of a bill of $26.37
We just multiply 26.37*0.19=$5.01

29. B) A population changes in response to a change in the environment.
<u>Evolution is the process by which new species of organisms develop from earlier forms. Most often, in response to a change in a species environment. It's the frequent change of the alleles in a population. </u>
30. A) Describes the relationship between an organism and its environment
<u>Darwin made this theory of evolution by natural selection as an explanation for adaptation. Darwin defined natural selection as the </u>
<u>"principle by which each slight variation, if useful, is preserved."</u>
Answer: Solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.
Explanation:
A process in which solid substance converts directly into gas without undergoing liquid state is called sublimation.
For example, when solid ammonium chloride is heat in the apparatus then it will convert directly into vapors without undergoing liquid state. During this process it leaves behind anhydrous chloride into the mixture itself.
When these vapors are cooled down at the surface of funnel then it gives ammonium chloride in the solid state.
Thus, we can conclude that solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.
