Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
The four phases in the life cycle of a cell and place the events in order, starting with events that occur immediately after the cell was born are:
- The first gap (G1)
- The synthesis (S)
- The second gap (G2)
- M
<h3>What is a cell?</h3>
A cell can be defined as simplest, basic, functional and structural unit of life
In conclusion, the four phases in the life cycle of a cell and place the events in order, starting with events that occur immediately after the cell was born are:
first gap (G1), synthesis (S) scond gap (G2) and M

Answer:
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
For both ectotherms and endotherms, metabolic rate tends to increase as mass increases
As the masses of the dinosaurs increase, how do their metabolic rates change? How does this compare to living animals?
>> As with living animals, the higher a dinosaur’s mass, the higher its metabolic rate.
