Answer:
Radiogenic isotopes.
Explanation:
Dating is a process by which archaeologists get to know the absolute or relative age of a past objects. Absolute dating deals with the process of determining the absolute age of the element. During dating of objects, or during the radiometric dating if we know the half-life of the element, it will be easy to know the age of that object by determining the decay rate of the isotopes.

Answer:
D. The threat of predators to eat eggs
Explanation:
The internal gestation followed by live birth was an adaptation developed by the mammals on land, and by some fish in the water, like the sharks. The mammals have been the most marking ones in this adaptation though. They too were producing eggs initially, but because they were living in an environment where there were numerous animals that preyed upon them, as well as their eggs, they had to be innovative. They developed internal gestation, where the embryo was developing inside the body of the female, and then it was born alive. This was providing extra safety, as the embryo was always with the mother, instead of being left alone and not guarded, thus an easy meal for the predators. The two types of internal gestation that the mammals developed are the placental and marsupial types, with the placental turning out to be more successful over time.
