Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase
of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses. The molar teeth developed and became stronger. Which statements are supported by this evidence? The digits of the horses’ feet underwent modifications, enabling them to run faster from predators.
The molars of the horses underwent changes so they could chew meat.
The emergence of grasslands over time led to the development of strong molar teeth in horses.
The digits were modified to enable the horses to graze better on hard, rocky surfaces.
Molars became bigger to fit into the jaw structure of modern horses.
They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves.
Amylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules).
In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
