Spring tides occur during the full or new moon phases when the moon's and the sun's gravitational forces act together on Earth, affecting both the crust and ocean waters, leading to higher tidal levels than usual. In contrast, neap tides arise when the moon and sun are positioned at right angles relative to each other.
Cellular membranes primarily consist of lipids such as phospholipids and cholesterol. Phospholipids are composed of glycerol, fatty acids, phosphate, and various organic groups including phosphoinositol and choline. Cholesterol plays a crucial role in regulating the membrane's fluidity and is involved in the signaling processes of the membrane.
