(a) Let a sequence of a integer x have a length of n, n is less than infinity, and let this sequence be part of the infinite sequence of integers in the square root of 2. Is it true that for every sequence of length n there is a sequence of length n+1 for the same integer x?

(b) What about for an irrational number y = k sqrt(2)?

(c) Find a function f(x,n,j) that is equal to 1 when for a sequence of integers x of length n there is also a length n+1 contained in some real number j and zero when this is not true. Express this function in terms of an infinite series. (For example, f(9,2, pi)=1 because there is a sequence of 2 9s at about the hundreth decimal place.)

Hi, I am having trouble answering these 2 questions. I have already searched my book.

First, which of the following cell components is not directly involved in synthesis or secretion?
Smooth ER, Golgi Apparatus, Rough ER, or lysosome.
According to my book (Campbell and Reece) they all seem to be involved in those processes.

Second, The structural filament most actively involved in movement of molecules and organelles within the cell is the:
intermediate filament, microfilament, microtubules, or all participate equally.
I am unsure about this one because my book implies that all participate, but it does not imply that participation is equal.

Please help I have my midterm this week and I want to be ready. Thanks in advance!
