Select all the correct answers. 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.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
