Penetration of the egg' zona pellucida by the sperm cell is a process driven by hydrolytic enzymes.
<span>
The critical step in fertilization is binding between sperm receptors and glycoproteins on the zona pellucida. This is the trigger for the acrosome reaction which includes an influx of CA and a rise in pH and cAMP levels within the sperm head. As a result, the plasma membrane of the sperm fuses with the outer acrosomal membrane and the exocytosis of the acrosomal<span> vesicle occurs. Components of the acrosome, like hydrolytic enzymes, are released and they degrade the <span>zona pellucida allowing</span> the sperm to move </span>inside.</span>
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
It is true that all GAL structural genes have UAS elements in their enhancer regions.
UAS elements can be found in the enhancer regions of every GAL structural gene. An enhancer is a short portion of DNA (50–1500 bp) that can be bound by proteins (activators) to increase the likelihood of a particular gene being transcribed.
The GAL4-UAS system is a biochemical technique used to investigate gene expression and function in fruit flies. Two parts make up the system: the Gal4 protein, which is an activator of transcription in yeast, and the UAS (Upstream Activation Sequence), which is an enhancer to which GAL4 binds specifically to initiate transcription.

maybe it's called osmosis?
