If two organisms are in the same phylum, which other classification category must they also share? a. class b. order c. kingdom

The correct answer is option C, that is, kingdom.

Explanation:

Taxonomic ranking refers to the hierarchy system used for the classification of the organism. In this ranking, domains are differentiated into kingdoms, the kingdoms are differentiated into phylum. The phyla are differentiated into class, and the class is further differentiated into orders.  

The orders are differentiated into the genus, and the genus is ultimately differentiated into species. The phylum is classified as lower to the kingdom and higher to the class. Thus, the organism coming under the same phylum must exhibit a similar kingdom.  

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
