Answer:
The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.  
Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.  
The total recombinants from 1000 plaques will come out to be 80,  
Thus, the recombinants of each type will be 40.  
Total parental type will be 920, and therefore, each parental type count will be 460.  
Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
 
        
             
        
        
        
Answer:
Option a, survive in extreme environments
Explanation:
Both Thermus and Deinococcus belong to the group of bacteria that are collectively termed as Deinococcus–Thermus group. 
Deinococcus are radiation-resistant vegetative cell as they are able to resist ionising radiation. Also some species of Deinococcus are thermophile. 
Thermus are thermophilic bacteria that are able to live in extreme temperature condition and thus are able to tolerate high temperature.
Hence, option A is correct.
 
        
             
        
        
        
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus. They have the same number of sets of chromosomes, one set in the case of haploid cells and two sets in the case of diploid cells. In most plants and all animal species, it is typically diploid cells that undergo mitosis to form new diploid cells. In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new haploid daughter cells. The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only. This is half the number of chromosome sets in the original cell, which is diploid.
