There are 4 electrons altogether shared between carbon atoms in a molecule of C2H4, to be more precise there are 2 electron pairs shared between the carbon atoms.
Answer:
Dead plant matter
Explanation:
Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
Answer:
hopes it helps
Explanation:
In glycolysis, glucose molecule is converted into pyruvate molecules .
It can't be cellular respiration because it starts always with glucose i.e glycolysis. But here it is the process after glycolysis (starting from pyruvate) and changing into lactic acid. It's an aerobic respiration called as lactic acid fermentation.
Answer:
the answer is F oxygenated blood circulates back into the heart and is then pumped to all parts of the body through the arteries
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.
