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.
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.
The answer for this question would be the second option. Genomic studies cover the analysis of the changes of genome by scanning the markers across complete sets of DNA. Based on these studies, the change in gene sequences happen that resulted to a change in the way that the brain interprets speech in between 4 and 9 million years ago.
