Explanation:

Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylation, is relatively unknown. Recent discoveries have shown that many of the protein phosphatases are involved in the temporal and spatial control of mitotic events, such as mitotic entry, mitotic spindle assembly, chromosome architecture changes and cohesion, and mitotic exit. This implies that certain phosphatases are tightly regulated for timely dephosphorylation of key mitotic phosphoproteins and are essential for the control of various mitotic processes. This review describes the physiological and pathological roles of mitotic phosphatases, as well as the versatile role of various protein phosphatases in several mitotic events.

Why are decomposers important to the environment?

Simora [160]

Answer:

They provide nutrients for the growth of plants

Explanation:

When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.

Answer:

Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae or Escherichia coli

Explanation:

Meningitis is the inflamation of the meninges (membranes that cover the brain and spinal cord) due to the infection of the fluid around it. Some of the symptoms are fever, sleepiness, nausea and vomiting, stiff nech and seizures.

Meningitis can be caused by Gram negative bacterie such as H. influenzae., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa or Serratia marsescens. From these options only Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae and Escherichia coli are rod-shaped gram negatives.

Aleonysh [2.5K]

Answer:

El Niño is defined as an unusual weather pattern seen in the Pacific Ocean. In this weather unusual winds allows the surface water to get warm from the equator to move east, that is toward Central and South America.

So, El Niño affects wind shear, in which air current present in lower altitude moves to different direction from winds higher in the atmosphere and affects weather patterns. such as El Niño is responsble for more rain in South and Central America and in the United States.
