Answer: Carbonic acid occurs naturally in the body and performs important regulatory functions.
Explanation: Carbonic acid ( ) is an acid formed from the carbon dioxide present in the body. It is also known as the respiratory acid as it helps in the transport of carbon dioxide in the body.
With the help of enzyme Carbonic Anhydrase, carbon dioxide is converted into carbonic acid. This acid is an unstable intermediate which gets dissociated into bicarbonate ions ( ) and
ions. immediatley.
Therefore, Carbonic acid performs important regulatory functions in the body.

Answer:
C. Gamma > beta > alpha
Explanation:
<u>Alpha rays</u> : These are positively charged and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.
These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).
<u>Beta rays</u> : They are negatively charged and have negligible mass.
On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.
<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.
