Biotic and living are the same thing, abiotic would be non-living
In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.

=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>
Answer:
Double-stranded DNA.
Explanation:
Replication may be defined as the process of formation of the daughter DNA from the parent DNA with the help of enzymes and proteins. The three main process of replication are inititation , elongation and termination.
The double stranded DNA molecule undergoes the process of replication. Four different dNTPs - adenine, guanine, thymine and cytosine are required for the process of replication. Primers are required for initiation of the process of replication and ori region is the inititaion point of replication.
Thus, the correct answer is option (a).
When taken out of the freezer and placed on a piece of foil, 2 pieces of ice will melt at the same rate because the piece of foil is at room temperature and so are the pieces of ice.
That's the best way that I can explain it :)
