S- Cyclin as it passes through the S phase is low in early G1, it the rise slowly through late G1 and S, peaking in early G2 and then dropping sharply back to zero in early Mitosis phase.

Cell often moves to the next stage of the cell cycle. The cyclins that were active in the previous stage are reduced.

Cyclin plays a role of regulating the cell cycle when they are tightly bound to Cdks.

Interphase is made up of G1 phase (cell growth), S phase (DNA synthesis), and G2 phase (cell growth). At its end of interphase comes the mitotic phase,.

It is known to push the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks).

Conclusively,Cyclin levels is not stable during the cell cycle, which is the main regulation by transcriptional activation and proteolytic destruction.

Answer:

Cyclin levers are relatively low but increases strongly when needed. Going deeper into the topic, we can say that G1 cyclin increases at the beginning of G1 and starts decreasing throughout the whole cycle. The G1/S cyclin level starts increasing from mid G1, reaches its peak at the beginning of S, and decreases again mid S phase. The S cyclin however starts increasing 3/4th its way through G1, reaches its peak mid G2, and decreases completely at the M phase. Finally the M cyclin levels start increasing from the beginning of the S phase, peaks at the very beginning of mitosis, and falls dramatically at mid mitosis.

Explanation:

Answer:

As the pH rises, the concentration (toxicity) of the ammonia also increases. When the pH level increases above 9, most of the ammonium in the water is converted into toxic ammonia (NH3), which can kill fish. ... The Nitrobacter bacterium feeds on the nitrites in the water and converts them into nitrate (NO3).

Explanation:

test the ph balance.

Final answer:

The conversion of ammonia to nitrate decreases pH levels, making the environment more acidic. This is critical because pH affects the availability of nutrients to plants and the health of soil ecosystems.

Explanation:

The pH level changes when ammonia is converted to nitrate as a part of the nitrification process. Ammonia (NH3) is alkaline by nature. As it gets converted into nitrate (NO3), the process consumes H+ ions, causing the pH to decrease, making the environment more acidic.

This is important because pH affects the availability of nutrients to plants and the health of the soil ecosystem. If the pH is too low (acidic), it can inhibit the growth of certain organisms and disrupt the balance of the ecosystem.
