What would happen if Cyclin proteins did not function properly in the cell cycle?
Cyclin proteins are important in cell cycle progression; they partner with cyclin-dependent kinase enzymes to allow the cell cycle to progress. Without them, cell cycle progression would be hindered/stopped.
The situation when the cyclin proteins should not be function properly in the cell cycle because it is arrested.
What is Cyclin degradation?It is the key step that governs exit from mitosis and it should be progress into the coming cell cycle. It is equally vital with respect to the progression that arise from the cell cycle. In this, the particular enzymes should be split down cyclines at the particular time with respect to the cell cycle.
At the time when there is decrease in the cyclin levels so the CDK should not be inactive. Also, the cell cycle should be arrest at the time when the cyclines fail to degrade.

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
Answer:
Nucleolus
Explanation:
This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.
The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.
What is nucleolus?The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.
The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.
It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.
The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.
It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.
Thus, the correct option is 1.

describe how sugar is transported around a plant 6Marks
Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.

A strand of DNA consists of 35% adenine. What is the percentage of thymine in that same
molecule of DNA?
PLEASE HELP ITS A TEST
Answer:
Explanation:
The percentage of adenine will equal the percentage of thymine, and the percentage of cytosine will equal the percentage of guanine. Together, these percentages will add to 100%. We know that the sample is 35% adenine, which tells us that it is also 35% thymine.
Answer:
The percentage of thymine would also be 35%.

1. If the ecosystem is balanced, which populations should be the largest? Which should be the smallest?
2. Why can the wolf be considered both a secondary consumer and a tertiary consumer?
3. If the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?
4. Analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? What would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? Describe how each level would be affected if each of these changes occurred.
Answer:
1. producers are the largest and consumers are the least
2. because wolves feed on both primary and secondary consumers
3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.
4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.
if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die
