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!

DOES A HUMAN CELL HAVE 46 DOUBLE OR SINGLE STRANDED CHROMOSOME?

Also, in my book, it says that during interphase, the cell replicates its DNA. Does that mean that the number of chromosomes are doubled?
