Answer:
Provides both the RNA and the polymerase needed for synthesis
Explanation:
Telomerase is an enzyme which extends the telomere sequences present at the end of the chromosomes. The telomerase enzyme acts as DNA polymerase as well as provides the RNA which serves as a template strand rather than the primer.
The polymerase acts as a reverse transcriptase enzyme and synthesizes the DNA strand from the  RNA template. Since the telomerase provides RNA and acts as DNA polymerase, therefore, it is known as the ribonucleoprotein molecule.
Thus, the selected option is correct.
 
        
             
        
        
        
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.  
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.  
Hence, both potential difference and voltage drop occurs across the circuit,  
Option D is correct.
 
        
             
        
        
        
C. Asthma
- Goitre is due to lack of iodine in diet.
- Arthritis due to inflammation of the joints.
- Bone cancer due to radiation.
- Asthma due to intake of harmful gases like CO₂.
