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.

A bacteria can do all of the following 1. Photosynthesis 2. Recycling carbon which contributes to carbon cycle 3. Nitrogen fixation which contributes to nitrogen cycle These three indicated functions are significant because they perform specific contributions in the biosphere. Phosphorylation is a function which is part of the ATP process and has nothing to do with bacteria.</span>

Answer:
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. ... It is because density in an intensive property of matter. So they are not considered properties.
Explanation:
