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 answer to that would be B. This is because carrying capacity is the amount of something that can be handled.
Answer:
Tissue fluid consists of water, ions, and dissolved gases and food substances, which is formed when blood is ultrafiltered from the capillaries into the intercellular spaces. The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels.
Lymph is a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream. It is essentially tissue fluid that has entered a lymphatic capillary. Lymph formation depends upon tissue fluid formation.
