Answer:
The correct answer is option 3. a nucleus.
Explanation:
The first genetic material present in the early organisms were RNA which was present in the microscopic organisms back then 3.5 billion years ago which means it is normal to have RNA in such microfossils chemical analysis.
Since, the nucleus was not present in early life forms of prokaryotes like bacteria. so, it is unusual to find nucleus in the fossils of stromatolite rocks.
Thus, option III is the correct answer.

Answer:
0mg/min
Explanation:
Glycosuria is a disorder in which glucose is excreted in the urine despite its normal or low blood concentration.
Urine contains very small amounts of glucose, as the proximal bypassed tubule reabsorbs virtually all of the glucose, but if the patient has hyperglycemia that exceeds the renal reabsorption threshold (160 to 180 mg / min), there will be glycosuria. For this reason, we can conclude that if a person has a tubular glucose load equal to 125 mg / min. The amount of glucose in the urine will be approximately 0mg / min.

Explanation:
Giuseppe Mercalli (1850-1914) originally developed the scale, with ten levels. In 1902, Adolfo Cancani extended the scale to include twelve levels. August Heinrich Sieberg completely rewrote the scale. For this reason, the scale is sometimes named Mercalli-Cancani-Sieberg scale, or MCS scale.
