Sorus is a structure that contains spores and is located on the underside of fern leaves. Sorus is a cluster of sporania. In fungi and lichens, the sorus is surrounded by an external layer. Sorus can be also called a fruit dot.
Answer:
A bilayer containing lipids with hydrophilic head groups facing the extracellular fluid and cytoplasm, and hydrophobic tail groups extending inward.
Proteins and Lipids
The biological membrane bilayer is held together by non covalent interactions.
Explanation:
The structure of the biological membrane is such that the major components found in this membranes are phospholipids although other components are present including various proteins, glycolipids etc. These phospholipids forms a bilayer (two layer) and each phospholipid has an hydrophilic head group (which is attracted to the fluidic environment both extracellular and cytosolic environment) and a hydrophobic tail (which is insolube in both environment). the arrangement is such that the hydrophilic heads of both bilayer that love water faces these two envirionments while the hydrophobic tails of both layers extend towards each other.
The biological membrane bilayer is held together by non covalent bonds. the proteins and lipid molecules in the bilayer are held together by this non covalent bonds including van der waals forces which also holds the hydrophobic tails together. the hydrogen bonds bind the hydrophilic heads with water allowing for the stabilization of the structure.
Tropical Disturbance
Tropical Depression
Tropical Strom
Last but not least the tropical cyclone
<span>The vertebrate nerve code is found dorsally while that of the crayfish is located ventrally of its body. Additionally, the ventral nerve cord of the crayfish is a solid ventral tube while that of the vertebrate is a hollow tube. All vertebrates are chordates, the dorsal nerve cord develops into nervous tissue of the brain and spinal cord; unlike the notochord which is the scaffolding for development of the bone and cartilage of the vertebral column. In the crayfish, they have a ventral nerve cord which is a collection of nerves found in the abdomen.</span>
