Answer:
C- DNA
Explanation:
DNA is responsible for protein synthesis.
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.
The answer is; D
The plasticity of rock in the mantle and the convection currents in the region are responsible for tectonic plate movements. The hot molten rock from deep in the mantle rise and is replaced by the cooler rock at the upper mantle. These convections are similar to those of water in a boiling pot. As the tectonic plates move (as they are dragged by these convections) and collide, earthquakes are caused. In addition, at subductions zones (where two plates collide) there occurs high volcanic activity.
Answer: The answer is, use of fertilizers (manure) in farming this is on study island
Explanation:
Answer:
The environmental factors which need to be investigated before clearing the land can involve living and non-living factors. The land clearing will remove species of animals and plants acquiring their habitat in the forest. The loss of floral species will affect the faunal species. The faunal species will extinct, decrease in number or may migrate to different locations. Therefore, complete loss of biodiversity will result.
This will also result in disturbance important cycles in nature like water, oxygen, nitrogen and carbon which will lead to disturbance of rainfall, seasonal or weather changes. Soil an important non-living factor will loose it's fertility due to soil erosion.
