Question

Match each scenario with a component of natural selection. (4 points)
-There is a field full of rabbits. They reproduce leading to an increase in population, but there's only so much clover to eat. This leads to competition!
-Over time, there are more brown rabbits because they pass their genes to their offspring.
This helps the rabbits survive in the field.
-Some rabbits are brown, some are almost white. This difference is due to variations in their genes.
-Hawks love to eat white rabbits. Brown rabbits, hidden in the grass, survive longer and have more offspring.
:: Genetic variation
： Selection
:: Overproduction
： Adaptation
When are two individuals considered to be the same species? (1 point)
• They are able to produce offspring.
• They have a similar number of chromosomes.
• They have a recent common ancestor.
• They are able to produce fertile offspring.

Answer 1

Matches:
- Field full of rabbits, reproduce but limited clover → Overproduction
- Over time more brown rabbits because they pass genes and this helps them survive → Adaptation
- Some rabbits are brown, some almost white due to gene differences → Genetic variation
- Hawks eat white rabbits so browns survive longer and have more offspring → Selection

When are two individuals considered the same species?
- They are able to produce fertile offspring.
