using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene

1 answer:

3 0

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Answer:

Loss of electrons and hydrogen ions are generally involved in oxidation reactions in biological systems

Explanation:

The substrates involved in the oxidation reaction in biological systems often loss hydrogen ion detached from itself and thereafter an electron is removed. The substrates are then oxidized by the addition of oxygen to the substrates.

These processes are catalyzed by Oxidoreductases and oxidation takes place alongside with reduction.

Dan has noticed that when he adds fertilizer to his garden soil his strawberry plants seem to grow better. Dan wonders if it is

madreJ [45]

The correct answer is - the variable.

With the experiment, in the way that Dan had decided to perform it, the fertilizer is the variable, as in one of the parts with strawberries he uses fertilizer, while in the other part he doesn't uses fertilizer.

While this kind of experiment may give Dan some answers, and he might notice differences, still he would have to be more detailed in the experiment to see for sure if the fertilizer is the thing that makes some of the strawberries grow better than the others.

Dan should also put all of the strawberries at places that would receive the same amount of light, experience the same weather conditions, receive the same amount of water, and to be planted in a soil of the same quality. Only like this, after putting the fertilizer, Dan can now if it makes any changes or not.
