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.

Baby's head must be large and must grow rapidly because its brain during the first 9 months of growth reaches half of its adult size. So, the head has to (compared to the size of their body) accommodate that brain. Sometimes it is even bigger than one-quarter of full baby’s length.

P700 is photosystem I. It includes chlorophyll a 670, 680, 695, 700, Chlorophyll b, carotenoids. The active reaction center of photosystem is p700, as it absorbs light of a wavelength longer than 680nm.
P680 or the photosystem II has the following pigments: chlorophyll b, 660, 670, 680, 695, 700, phycobilins, and xanthophylls. The active reaction center, in this case, is p680 of chlorophyll a, as it absorbs the light having a wavelength shorter than 680nm.
