Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with <u>1 mole per dm3 sodium chloride solution.</u>
<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
Answer:
the answer is D. lack of genetic variation
Explanation:
Populations evolve, individuals do not. It is incorrect to say that individuals adapt to their environment because adaptation occurs as a result of random mutations. Changes in the individual during its lifetime, such as phenotypic plasticity, is not adaptation.
Explanation:
Four images are shown in each set of PET scans to highlight either ,, blood glucose levels ,, cancerous tumour cells ,, whether or not vital organs are working correctly - or if the treatment of what is being given to the patient is working or not . more than one PET image may be taken of a subject's brain to see if the results are reliable and conform to the problem .
