Answer:

In a global sense, Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.

Explanation:

First step: 12. Glycolysis takes place in the cytoplasm and breaks down glucose to form two molecules of pyruvate. 2 ATP are produced and NADH is saved for later.

Second step: 13. Two molecules of pyruvate move into the mitochondria where they are converted into Acetyl CoA. More NADH is produced and CO2 is released.

Third step: 1 1. In the Citric Acid/Kreb's Cycle the carbons that are left from the initial glucose are oxidized releasing more CO2. NADH and FADH2 and 2 ATP molecules are produced.

Fourth step: 14. In the electron transport chain, the NADH and FADH2 give up electrons, energy is released and captured as it moves from a high concentration to a low concentration.

Finally, 15. Energy is used to produce about 34 ATP. Oxygen is the terminal electron acceptor that combines with oxygen to produce water

We can conclude that Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.

Answer:

The steps will be in order in the sequence 12,13,11,4 and 15

Explanation:

12. In glycolysis, glucose is converted into pyruvate. ATP and NADH ARE MADE.

13. Pyruvate is oxidized and converted into acetyl CoA in the mitochondria. Carbon dioxide and NADH are also made.

11. The acetyl CoA undergoes a series of changes and ATP, FADH2, NADH, and carbon dioxide are released.

4. NADH and FADH2 lose their electrons and get converted back into NAD+ and FAD.

15. Oxygen takes electrons and water is produced. 34 ATP molecules are released.

3. How are frog eyes different from human eyes?

Nastasia [14]

Answer:

Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.

Most aquatic organisms can survive only within a specific pH range. An increase in the number of hydrogen ions (H+) in a lake wi

Ipatiy [6.2K]

Answer:

An increase in the number of H+ ion in the lake with many aquatic would cause cell shrinkage by the removal of water from the cell.

Explanation:

Every organism tries to maintain a constant PH inside their body to regulate the homeostasis of their body.

An increase in the number of H+ ion or proton in a lake will increase the osmotic pressure of the water present in the lake.As the osmotic pressure of Lake"s water is increased it will draw water out from the the cells of aquatic organism causing the cells to shrink thus decreasing the volume of the cell and if the H+ ion concentration rises at a high level cell death can occur.

Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of w

sp2606 [1]

Answer:

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year 1950 1965 1975 1990 2005

Amount 180 340 420 410 410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.

Who is most in danger from the effects of overfishing ?

faltersainse [42]

I don't think we can answer this question just like that. The question should be formulated a bit differently:

WHAT is in danger from the effects of overfishing?

Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:

1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.

2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.

3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.

Hope it helped,
