Which of the following statements about the nuclear envelope is false? a. the nuclear envelope is continuous with the golgi apparatus. b. molecules pass into and out of the nucleus through nuclear pores. c. nuclear pores are made up of a group of proteins that are collectively called the nuclear pore complex. d. the nuclear envelope is composed of two lipid bilayers. truefalse

These statement are all true:

B. Molecules pass into and out of the nucleus through nuclear pores.

C. Nuclear pores are made up of a group of proteins that are collectively called the nuclear pore complex.

D. The nuclear envelope is composed of two lipid bilayers.

The statement that is false is:

A. The nuclear envelope is continuous with the Golgi apparatus.

The outer membrane of the nuclear envelope is continuous in many places with the rough endoplasmic reticulum. Just the same as the rough ER the outer membrane of the nuclear envelope is dotted with ribosomes.

gold i'm pretty sure i might be wrong

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
