Answer:
B
Explanation:
I'm pretty sure that's the answer because the others seem very odd for a population scale when a new pipe is inserted.
Answer:
cell wall, cell membrane, cytoplasm, vacuole, ER and nucleous
Explanation:
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>
<span>During process 1→3→6, the temperature of the gas decreases slowly during process , the temperature of the gas rapidly decreases and then increases increases and then decreases remains constant. Hence, in the first step, the temperature of gas decreases slowly, then decreases rapidly, then it increases and finally the decreases becomes constant.</span>
