Answer:
The five true statements are numbers: 1, 2, 5, 6 and 7
Explanation:
1. Temperature drives water movement in some lakes.
2. Tropical coral reefs generally exist in relatively shallow areas of the ocean.
5. Wetlands have slow water movement or no water movement and no turnover.
6. Estuaries are very productive and are used as breeding grounds by many species of fish.
7. A freshwater organism permanently attached to the substrate would be unlikely to survive and reproduce in an estuary.
Answer:
ΔS will be positive.
Explanation:
Denaturation may be defined as the loss of the biological activity of protein by changing the physical conditions of protein. Protein can be denatured by increasing temperature, pH and salts.
Entropy may be defined as the randomness of molecule. The entropy increase with increase in the randomness of the substance. Since, protein has been denatured, the random coil confirmation increase. This means the randomness of protein has been increased, this increase the entropy and makes it more positive.
Thus, entropy becomes more positive.
Bacteria that have
taken up the plasmid with antibiotic resistance
gene will grow in a medium laced with the particular antibiotic of interest. More
so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments
are used with selective media that only allows the bacteria with a particular characteristic
to grow.
