They are the sites at which microtubules attach to chromosomes.

The perfect paging size varies from system to system, so there is no single best when it reaches to page size. There are several factors to consider in order to come up with a fitting page size, such as paging time, page table, and its effect on the total performance of the operating system.

Electronegativity is the tendency for an atom to attract electrons. There are general trends on the periodic table which you can use to determine the relative electronegativity for different elements, but otherwise you can also look at their valence shell and effective nuclear charge to determine their relative electronegativity.

Here from the given options, Lithium has least tendency to attract electrons and thus has a lower electronegativity.

From the given equation,

88x370/100 + 24x210/100 - 118 = x

=> x = 325.6 + 50.4 - 118

x = 258.
