20 is the Number of Neutrons of potassium.
KIA tubes and SIM tube in this exercise to determine whether or not your unknown produced H2S.
<h3>What gas is produced by Salmonella?</h3>
F0F1 ATP synthase activity is necessary for Salmonella typhimurium to produce hydrogen sulfide and fermentative gases.
<h3>H2S production by Salmonella enterica?</h3>
Infections with Salmonella enterica continue to have a serious impact on global public health. H2S-negative Salmonella have lately surfaced, despite the fact that the capacity of S. enterica to produce H2S is an essential phenotypic trait utilized to screen and identify Salmonella with selective media.
<h3>H2S is it produced by Shigella?</h3>
Shigella do not create H2S, hence colonies on Hektoen agar appear bluish-green rather than having the black center seen with Salmonella. Shigella are comparatively biochemically inactive and do not ferment lactose or xylose.

Answer:
DNA helicase
Explanation:
DNA helicase unwinds the DNA strands by breaking the hydrogen bonds down at the center of the strand. this process begins in the replication fork of the DNA strand
The scientist that presented that deoxyribonucleic acid contained equal quantities of certain nitrogen bases is Chargaff. In addition, Chargaff’s rules state that deoxyribonucleic acid from any cell of all organisms must have a 1:1 ratio which is base pair rule of pyrimidine and purine bases and more precisely that the total of guanine is equal to cytosine and the total of adenine is equal to thymine. This configuration is found in together strands of the deoxyribonucleic acid.
this is because the blood flow slow through the capillaries to allow gaseous exchange. Plus the pressure is higher in capillaries because the diameter of the capillaries is smaller than arterioles
