Selective permeability is when a cell membrane allows some molecules or ions to pass through it, but not others.
Answer:
The correct answer is - C. protein - Millons' test - red precipitate is formed.
Explanation:
The iodine test is the test that is used for the identification or presence of the starch in a food sample, in this test if starch present in the food then the solution of iodine and KI will turn to deep blue color. Therefore the given result is incorrect
The benedict test for confirming if glucose present in the sample, it is a mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate which starts as aqua blue in color but after adding sample and gradually heating it turns from yellow to orange as per the concentration of the glucose. Thus, it is incorrect.
The emulsion test also produces the milky precipitate or emulsion in presence of fat or lipid in the sample. so, it is incorrect.
Millon's test for protein is the test that results in the red solution or red precipitate in the presence of the protein in the sample.
Answer:
Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
Explanation:
Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment. All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.
Hence, option A is correct.
