Answer and Explanation:
Cyclins and cyclin-dependent protein kinases (CDPKs, cell proteins) also function to control the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins (mitotic cyclins) to be synthesized. M cyclins activate a second group of CDPKs which allow the cell to pass the G2/M control point and into mitosis.
In the G1/s check point, entrance into the S phase is blocked if the genome is damaged. In the G2/M check point, entrance into the M phase is halted if the DNA replication is incomplete. In the M phase, anaphase blocked if chromatids are not properly assembled.
Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
<span>Because the organelle undergoes process that converts biomolecules into a useful energy resource for cell activities that leaves the formation of carbon dioxide as an excess agent.
Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.

The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place. All these process take place under the cellular function of cellular respiration.<span> </span></span>
