When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid gr

owth of algae in a process called eutrophication. How can this process affect other organisms in the water?
The water becomes better able to support aerobic organisms.

Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.

The algae provide food for fishes and other organisms, leading to decreased algae populations.

The extra nitrogen provides additional food for the other organisms, increasing their population.

The correct answer is '<span>Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.</span>' The additional nutrients in the water will result in an algal bloom. These algae will result in drastic oxygen fluctuation, from oxygen rich conditions during the day as algae photosynthesize, to anoxic conditions during the night when the algae respire. However, the algal bloom will eventually deplete the available nutrients, resulting in a vast algal die off. The decomposing algae result in anoxic conditions, and the effects are sometimes very obvious, with fish gasping for breath and dying.

I'd also say that the morphology presented in this picture is filamentous.
The reason for my believing this is that filamentous morphology concerns long visible chains, threads, or filaments, which you can see in the image.

Roberta makes a $9 an hour plus a 12.5% commission selling jewelry how much does she earn on a 8 hour shift which she sells $380
aivan3 [116]

Answer:

The amount Roberta makes an hour is $119.5

Explanation:

Let the number Roberta makes be x hours.

Amount earned in x hours shift - 9*x + 12.5% of the amount of jewelry sold.

Number of hours worked by Roberta if 9 hours and jewelry worth $380 is sold by her.

Substituting the values:

Amount earned in an 8 hour shift = 9*8 + 12.5% od 380

= 72 + 0.125 * 380 (12.5% = 0.125)

= 12 + 47.5

= 119.5

2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr
atroni [7]

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

             NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

         Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

              That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.

What is the role of alveoli in respiration
Burka [1]

Answer:

<em>What is the role of alveoli in respiration ⇔ Alveoli are the place where the exchange of gases takes place. The outer part of alveoli has blood vessels. These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. </em><em>The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.</em>

Explanation:
