In normal cells, stathmin is inactivated by phosphorylation at the start of M phase. Phosphatases remove these phosphates as the cell transitions from M phase to G1. What enzyme is likely to be responsible for phosphorylating stathmin during M phase
Answer:
The enzyme that is responsible for this is the cyclin dependent kinase subunit of mpf
Explanation:
This enzyme is also known as cyclin dependent kinase subunit, CDKs. they are protein kinases and can function as cell cycle regulators. They have the power to modify different protein substrates that are useful for the progression of cell cycle. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.
The enzyme that is likely to be responsible for phosphorylating stathmin during M phase is the cyclin dependent kinase.
Cyclin-dependent kinases:
Cyclin-dependent kinases (CDKs) are protein kinases characterized by needing a separate subunit - a cyclin - that provides domains essential for enzymatic activity. CDKs play important roles in the control of cell division and modulate transcription in response to several extra- and intracellular cues. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.Full kinase activity requires an activating phosphorylation on a threonine adjacent to the CDK's active site.Learn more:

which is an abiotic factor that can be found in a rain forest ecosystem
Answer:
Climatic factor.
Explanation:
Climatic factor is an abiotic factor that can be found in rainforest ecosystem. The climate along with the nature of soil and water is an area determine the type of organism found in the area,In fact both living and nonliving component influence each other.Among the abiotic factors the most important are climatic and edaphic factors.The climatic factors include air, water, light, temperature and humidity the edaphic factor refer to soil.

What is a density dependent limiting factor that affects population size?
-Drought
-Climate
-Natural Disasters
-Disease
Answer:
Disease
Explanation:
In Ecology, certain factors that affect the size of a population can either be dependent on size or not. Density-dependent factors are those factors that affect population of organisms in dependence of how dense the population is. Examples of these density dependent factors are diseases, predation etc.
For example, a certain disease will spread faster among a population of organisms whose size is dense but slower in a scarcely densed population. Hence, disease as a factor is dependent on population size. Note that; Drought, Climate, and Natural Disasters will wipe out a population irrespective of its size.
Answer:
Disease

How does the environment influence populations of organisms over multiple
generations?
Answer: Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. ... Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.

Water is transpired through stomata, but carbon dioxide also must pass through stomata into a leaf for photosynthesis to occur. There is evidence that the level of carbon dioxide in the atmosphere has not always been the same over the history of life on Earth. Explain how the presence of a higher or lower concentration of atmospheric carbon dioxide would impact the evolution of stomata density in plants.
Answer:
Escribir en español, por favor.?
During those high-carbon-dioxide times, plants that produce fewer stomata,
when carbon dioxide levels are low, plants need many stomata in order to scrape enough carbon dioxide to survive.
How does carbon dioxide affect water uptake?Plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open.
Thus, carbon dioxide levels are low, need many stomata in order to scrape enough carbon dioxide to survive.

A deletion mutation occuring in the region of DNA which encodes for a sigma subunit of RNA polymerase results in decreased binding to the promoter region of the DNA sequence which encodes for alpha, beta, and omega subunits of RNA polymerase. What is the effect
Answer:
The correct answer is - a reduced expression of alpha, beta, and omega subunits of RNA polymerase.
Explanation:
Sigma subunit of RNA polymerase is the subunit that the holoenzyme, the other part of the enzyme, identifies and attaches with the specific DNA site called promotors that is responsible for coding the alpha, beta, and omega subunits of this enzyme.
As it is given that there is a deletion in the sigma subunit due to mutation that results in decreased the sigma factor's binding affinity to the promoter region. That ultimately leads to less or unable to bind properly to the promoter and the level of gene expression to fall or be reduced.
