Answer:
Unlike prokaryotes, eukaryotic cells compartmentalize various metabolic processes inside membrane-bound organelles. For example, the breakdown of certain food molecules to provide energy takes place in the mitochondrion, and photosynthesis takes place in a chloroplast.

When they become metamorphic rock they are going through severe heat, causing the minerals to change.
If the tyre blows out then stop
Answer: The correct answer is -
D) giraffes having increasingly longer necks over time.
Natural selection is an evolutionary mechanism that was proposed by Darwin.
According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.
Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).
This is considered as a peculiar example of natural selection.
They are the basic units of structure because they are the smallest unit of life. you cant go any further. also they make up every living thing from prokaryote to eukaryote.
