Answer:
 Robertsonian translocation. 
Explanation:
 the disorder created as a result of the final chromosomal change that is shown is Robertsonian translocation. Translocation is one of the mutation that happens in chromosomes.
 
        
                    
             
        
        
        
Answer:
A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule
Explanation:
Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.
However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.
This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.
 
        
             
        
        
        
Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol,  SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses,  SRP binds to its receptor,   Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
 
        
             
        
        
        
Answer: Option A
<u>Explanation:</u>
As temperature increases the rate of enzyme activity increases until it reaches approximately 37 degrees Celsius. As temperature increases beyond 37 degrees Celsius, the enzyme activity decreases. The activity decreases because the enzyme denatures. 
Any enzyme has certain temperature, pH and pressure to maintain its activity. Only at the ideal or ambient parameters the enzyme works. Most of the enzymes that are present in the human body gets activated by 37 degrees and gets denatured beyond that temperature.
 
        
             
        
        
        
Answer:
Yes, meteorology could be useful when studying other planets such as Mercury and Mars; atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets of the solar system.
