C is right.

A: cancerous cells wouldn't last long if they died off. However, cancer is uncontrolled cell growth - so, by the very definition of cancer, A is wrong.
B: again, if it lost proteins and started breaking down, it's not mitosis, since the goal of mitosis is to produce 2 healthy cells from a single cell. If it lost some proteins while trying to reproduce, it would be wasting vital energy that it needed for the process of mitosis itself.
D: dosage compensating does occur - called X inactivation. This happens in females, since they have twice as many alleles from the X chromosome as males. Overexpression of these genes would mess up the female's physiology. Once more, dosage compensation does not kill the cell, as is being described in the question.

C is correct. Phagocytes literally "eat" cells. To do this, and be able to get the nutrients from inside the cell, it has to break down the outer defenses (cell walls, cell membranes, plasma membranes). The cytoskeleton provides the structural integrity for the cell, so it would also have to be disassembled.

Seeing as I am fairly sure it is not any of the others I would say engulfed by a phagocyte.

The youthful human beings team - 2 confronted habit - so pious in front of mom and dad, yet while allowed a house after sunday night worship devoid of parental supervision, did greater drugs, alcohol and unprotected intercourse than the so referred to as "druggies" on the highschool. 3. consistent harrassment for no longer having a clean outfit for church a week - for recycling the distinctive good clothing I did have. Aspersions solid on my mom and dad for no longer handing me a mastercard and sending me to the mall. on no account concepts I discovered to funds my funds, stay decently and replaced into dressed decently. 4. A minister who instructed my then destiny husband "in case you do no longer attend my church, then the bible would not prepare to you." those and too many different issues to checklist - in particular revolving around being overly worldly and much less and much less christ like. i could desire to declare it replaced into basically one church, basically one "form" of christianity, even though it wasn't. It replaced into greater detrimental to me and my spirituality to proceed to be around those human beings. So i ended attending any church, different than the occasional wedding ceremony and baptism. that's backsliding to no longer be around the enticements? Wow. exciting view you have of your faith then.
