<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome

Identical twins could not be considered as clones for they are different individuals which came from the same egg and sperm. Clones are produced asexually, a copy of another organism. Even though identical twins share the same DNA, they have different qualities as of the other twin which makes them their own unique self.
Answer:
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline. However, as the graphs in these three locations show, as CO2 rises, the pH drops, moving in the direction of the acidic end of the pH scale.
Explanation:
Answer: Classic seminoma
Explanation:
The classic seminoma can be defined as the germ cell tumor of the testicles or mediastinum. It is a type of malignant neoplasm and is treated and curable stage of the cancer.
It has a survival rate of more than 95 % if it is detected during the early stages of diagnosis.
It originates in the germinal epithelium of the semniferous tubules. In this case the fertility of the person is not affected and sexual function also remains intact.
The new hydrophilic amino acid would not form the same interactions with hydrophobic R groups. As a consequence, protein's 3D structure would likely be affected.
Different types of amino acids have different properties and thus form different interactions. For example, hydrophobic amino acids (water-repelent) such as alanine, valine, leucine, isoleucine, proline, phenylalanine, cysteine and methionine. participate in van der Waals type of interactions. They often form the hydrophobic core of the protein which doesn’t interact with water surrounding.
On the other hand, hydrophilic amino acids (arginine, asparagine, glutamine, aspartat..) are polar, can dissolve in the water and can join the hydrogen bond network.
