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.

An example of chemical digestion is the breakdown of __________ into __________.
vodomira [7]
starch into glucose
proteins
into amino acids
lipids
into fatty acids

There are many more examples of chemical digestion which takes place in the body. Chemical digestion is the breaking of larger more complex molecules into smaller, simpler ones that can be taken up by the cells more easily and readily by the use of chemical agents.. Chemical digestion is carried out primarily using biological molecules called enzymes. For example, the breakdown of starch is done by an enzyme known as amylase, which is present in the saliva.

What ingredients to reduce the acidity of water​
posledela

Answer:

I Think this answer will help

Explanation:

Soda ash/sodium hydroxide injection

This treatment method is used if water is acidic (low pH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.

How are the
svlad2 [7]

Given what we know, we can confirm that the three pathways of photosynthesis (C3, C4, and CAM) are all similar in that they use CO2 as the substrate in order to produce sugar, which is carbon-based.

<h3>Why are these pathways similar?</h3>
  • These pathways all produce carbon-based molecules in the form of sugars or carbohydrates.
  • These pathways are also similar in that they use carbon dioxide as the substrate in order to fuel these reactions and create sugar.
  • Finally, they are also similar in terms of the use of carbon and the production of carbon-based molecules in that they all use the Calvin cycle to complete this process.

Therefore, we can confirm that each of the three pathways of photosynthesis are similar in terms of carbon and the formation of carbon-based molecules in that each of them uses the Calvin cycle in order to turn carbon dioxide into sugars.
