Answer:
The correct answer is - Anaphase.
Explanation:
Cell division can be either mitosis or meiosis. Mitosis cell division has these phases:
A. Interphase - non-dividing phase with to G1, S and G2 sub phase. In this genetic material doubles and cell size increases.
B. Prophase- chromosomes shorten and condense by coiling. Centrioles move in opposite directions.
C. Metaphase - spindle fibres bind to kinetochores and pulls it the chromosomes on the equator of the spindle forms a plate called the metaphase plate.
D. Anaphase- these get condense and centromeres split into two and the spindle fibres pull the daughter centromeres to opposite poles.
E. Telophase is the last phase of Mitosis.

Integral proteins are embedded in the phospholipid layer, and can sometimes form protein channels that let ions and other small molecules through.

The correct answer is "5-1-3-2-4".
Explanation:
Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:
5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.
1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.
3) Several endocytotic vesicles fuse to form an endosome.
2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.
4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
