The bones are: malleus (hammer-shaped) , incus (anvil-shaped) and stapes (stirrup-shaped).
They are together known as ear ossicles.
They transmit the vibrations from the eardrum or tympanum to the inner ear.
Hi.
From my own knowledge, I remember that anorexia nervosa<em /><em> </em>matches what Jennifer is suffering from.

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.
Biodiversity increases as the number of populations grow, because a greater population generally means a more diverse one.
However, this is not always true, so I'm not sure what answer they're looking for.
