Hello!
I believe the best answer to your question would be Option C) excess carbon dioxide.
Hope this helps, and have a lovely rest of your day :)
Change in the external Environment may resulted in the changing in the population of beetles.
1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
