Answer: All of these aswers would be correct
Explanation:
<span>Cocaine Preparations
-Coca leaves --> Coca Paste (60% pure): Not water soluble, so you can't inject it into the bloodstream -- you need an additional chemical step to turn the paste into crystal powder that can be injected or snorted
-Coca --> Cocaine Hydrochloride (99% pure): Doesn't hold up very well to heat, so you can't smoke cocaine hydrochloride
-Cocaine Hydrochloride (99% pure) --> Free-Base Cocaine or Crack Cocaine:
-Reconvert cocaine hydrochloride back to base state by removing hydrochloride from cocaine (that's why it's called free-base cocaine)
-Crack cocaine is a crystallized form, mixture of cocaine and baking soda
-75% pure
-Can be used at lower doses and is much cheaper than cocaine
-Can be smoked</span>
Answer:
Evolution
Explanation:
Evolution is a gradual change in a population that occurs overtime in a species.
Answer:
The answer is A) Homologous structures
Explanation:
Homologous Structures:
- Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
- Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
- For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
- Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
- Inherited and developmental are out of context in terms of evolutionary relationships.
