The ph of the water in several lakes in norway and sweden had decreased to below 5.0 due to an increase in acid rain. What is mo
arsen [322]

Answer:

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.
