The correct option among all the options that are given in the question is the second option or option "B".
Answer:
Plus end and kinesin.
Explanation:
Three important cytoskeleton components are microtubules, microfilaments and intermediate filaments. Microtubules are the polymer of tubulin and plays an important role in the movement of cell organelles and its structure.
Microtubules shows the process of polymerization and depolymerization at different ends. The plus end shows the polymerization and minus end shows the depolymerization process. The kinesin protein is required for the process of polymerization.
Thus, the correct answer is option (D).
Pretty sure the correct answer would be Choice A
Layer that is 0.2 to 1.1 percent of Earth's total diameter is the thinnest layer of the Earth- Crust.
So, the correct answer is: oxygen and silicone. The crust consists of tectonic plates (in relative motion one from another) and has 5–70 km (~3–44 miles) in depth. The most abundant elements of this layer are: oxygen-46.6 percent by weight; silicon-27.7 percent; aluminum-8.1 percent; iron-5 percent.
