The correct answers are evolution, genetic mutation and selection.
The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.
These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.
There are chances that evolution took place over a period of time that changed the character in the horse.
Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.

The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.
Explanation:
The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.
Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind. Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.
