A Excess salt deposited in the soil when irrigation water evaporates is correct (apex)
When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.
(Hope this helps)
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.

the question you are looking for is
The ability of Salmonella to produce H2S is one characteristic that helps differentiate it from Shigella. List the three opportunities you had in this exercise to determine whether or not your unknown produced H2S.

Answer:
The intercalated cells in the distal convoluted tubule of a nephron can cause and increase or decrease in body pH.
Explanation:
The renal collecting duct is the nephron segment where the final urine content of acid equivalents and inorganic ions are determined.
Two types of cells regulate the acid-base and volume homeostasis.
Intercalated cells, which express acid-base transporters and vacuolar H+-ATPase, maintain an apropriate acid-base balance and principal cells that express the epithelial sodium channel ENaC and aquaporin 2, regulate electrolyte reabsorption.
Filtered bicarbonate is predominantly reabsorbed from the proximal convoluted tubule about 80% and the remaining bicarbonate is reabsorbed from the thick ascending limb of the loop of Henle, the distal nephron, specifically the distal convoluted tubule & the connecting tubule, and finally the cortical and both the outer and inner medullary collecting duct.
Intercalated cells are enriched in mitochondria, and express proteins involved in transport of proton equivalents such as vacuolar H+-ATPase, carbonic anhydrase II and bicarbonate transporters. There are two types of intercalated cells Type-A and Type-B.
<span>All are mutagenic because they cause base substitutions, deaminating agents oxidatively deaminate bases so cytosine converted to uracil and adenine converted to hypoxanthine, uracil pairs with adenine and hypoxanthine pairs with cytosine, alkylating agents donate alkyl group to amino or keto groups altering base pair affinities</span>
