Answer: Potassium-40 decays into argon gas over time.
Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.
Potassium-40 undergoes decay following first order kinetics as given below:

Answer:
Explanation:
the enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion. An enzyme's shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape
Asystole is defined as a cardiac arrest rhythm in which there is no discernible electrical activity on the ECG monitor. Asystole is sometimes referred to as a “flat line.” Confirmation that a “flat line” is truly asystole is an important step in the ACLS protocol.
Answer:
chemical reaction:-
12H20 + 6CO2 + light =====> C6H12O6 + 6H2O + 6O2
the above reaction shows that if we combine water,carbon dioxide and sunlight ,the resultant products will be glucose ,water and oxygen .
The plant converts the carbon dioxide into energy and oxygen by different steps that include
- absorption of light
- conversion of NADP into NADPH+
- conversion of ADP into ATP
- formation of carbohydrates from CO2 !
