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.

Answer:
You will need to prepare just incase it happens. Meaning buy grocceries, shelter and comfort items. And make sure to stay indoors at all times and stay away from windows or anything dangerous.
Hope this helps :)
If so brainliest would mean alot thanks!
Answer:
Some members of each group unicellular (& some colonial & some w/multicellular stages in life cycle)
-Mostly microscopic
No germ layer present
Specialized organelles; (found nucleus single or multiple, no organs or tissues)
-Free living, mutualism, commensalism, parasitism all represented in groups
-Locomotion by pseudopodia, flagella, cilia, & direct cell movements; some sessile
-Some provided w/simple endoskeleton or exoskeleton, but most naked
-Nutrition of all types
-Aquatic or terrestrial habitat
-Reproduction asexually by fission, budding, & cysts and sexually by conjugation or syngamy (union of male & female gametes to form zygote)
