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.
Answer:
Spirogyra is a genus of green algae that belong to the order Zygnematales. These free-flowing, filamentous algae are characterized by ribbon-shaped chloroplasts that are arranged in a helical manner inside the cells. So the name is derived from the spiral arrangement of chloroplasts in these algae.
Explanation:
Answer:
e) Political governance.
b) Health.
d) Personal activities, including work.
c) Education.
f) Social recreation issues.
g) Environmental conditions (current and future conditions).
a) Material life
h) Financial safety and security.
Explanation:
The quality of life is an index that is calculated by using different estimators that covers diverse aspects of human life such as, among others health, safety, happiness, security, transportation, etc. The INEGI (National Institute of Statistics and Geography, Mexico) calculates the quality of life by using the estimators above described (and others). In my opinion, the most important one of this list is political governance, because it is an underlying characteristic that has a direct effect on the further estimators, thereby affecting their performance in a short/medium-term period.
The right answer is HEPA filter.
A HEPA filter (High Efficiency on Particles Air) can filter up to 99.97% of 0.3μ aerial particles.
These filters are used to clean the air and retain suspended particles (dust, pollen, bacteria etc.) and other particles that can cause respiratory allergy in sensitive subjects.
They are very used in sterile rooms
