Joel notices that there is not much difference between low and high tide. what is happening?
Nostrana [21]

Answer:

This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise. So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around full and new moon.

Tectonic plants often shift position by the force of liquid rock emerging from below the earths surface and then cooling to form
Nezavi [6.7K]

Tectonic plates often shift position by the force of liquid rock emerging from blow the earth's surface and then cooling to form hard rock. This most often occurs On the ocean floor.

When tectonic plates move, They move along the ocean floor, which is the crust, and It cause earthquakes and volcanoes and also caused Pangaea to break apart and become what it is now, The seven continents.

Hope this helped :)

have a great day

Can someonee please explain the Krebs Cycle, glycolysis, and the electron transport chain? THANK YOU
Paladinen [302]
Hello! Cellular respiration can be confusing in textbooks and in general, so I've explained it in my own words the best I can to simplify it. :)

To start off, all of these processes are part of cellular respiration, which is a process cells use to extract energy from food and convert it to ATP, or energy.

Glucose + Oxygen <span>→ Water + Energy (ATP)

Here are the steps of cellular respiration:

1. Glycolysis- This process occurs in the cytoplasm. Glycolysis breaks down one molecule of glucose, a six-carbon molecule, into two three-carbon molecules called pyruvic acid. This process also produces four molecules of ATP, however, two molecules of the ATP are used in glycolysis, which means there is a net gain of 2 ATP molecules.

In short: Glycolysis= 1 molecule of glucose to 2 molecules of pyruvic acid/pyruvate, and also produces produces 2 ATP

Pyruvic acid is necessary to the next step of cellular respiration, which is the Krebs cycle.

2. Krebs Cycle (Citric Acid Cycle)- This process takes place in the matrix of the mitochondria of the cell. Pyruvate combines with coenzyme A before it enters the cycle. During the conversion of pyruvate to acetyl co-A, carbon dioxide is produced. Two rounds of this cycle occurs per glucose molecule.

In short: Krebs= Pyruvate + coenzyme A = acetyl coA, releases CO2 during this process, 3 NADH, 1 ATP, and 1 FADH.

3. Electron Transport Chain- This process creates a concentration gradient between protons, creating energy during chemiosmosis. This process produces 34 ATP molecules.

I hope this helps, and let me know if you have any questions! ^-^</span>
