Answer:
The correct answer is motion.
Explanation:
Lipids are the important constituents of plasma membrane. For example phospholipid,glycolipid,splingolipid,cholesterol builds most of the structural framework of the cell membrane.
Lipids plays an important role during cell signaling For example the phosphotidy inositol 4,5 bisphosphate one of important component of the inner leaflet of the the plasma membrane undergo hydrolysis to form Diacylglycerol(DAG) and inositol triphosphate(IP3).Both IP3 and DAG act as second messenger.
Lipid act as an insulator of myelein sheath that helps in the saltatory conduction of nerve impulse across the axon of unmyelinated nerve fibre.
Lipid does not involve in motion

Answer:
Pollination, the transfer of pollen from flower-to-flower in angiosperms or cone -to-cone in gymnosperms, takes place through self-pollination or cross-pollination. ... The placement of male and female flowers on separate plants or different parts of the plant are also barriers to self-pollination.
Explanation:
Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
