Answer:
B, C, Dand E are all correct
Explanation:
Why B is correct- The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit.
Plants, animals, and bacteria have a cell membrane. Why d is correcect
Why C is correct- The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.
Why E is correct- The plasma membrane is primarily composed of phospholipids arranged in a bilayer, with the hydrophobic tails on the interior of the membrane, and the hydrophilic heads pointing outwards
Why A Is Not correct- It is very fragile and its role is to hold the cell together and to help control what substances can get in and out. It is partially permeable, allowing only some substances to pass through it. The membrane has a complex structure consisting of a phospholipid bi-layer and different types of proteins.
Glucose binds to the glycogenin protein to form the glycogen polymer. Glycogen synthase uses UDP glucose as the substrate for polymerization via (1-4) bonds. The branching enzyme has two distinct functions: it breaks the linear chain and forms a branch using a (1-6) linkage.

What are nucleotides?</h3>
A nucleotide is the primary component of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base. DNA nucleotides include adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the nucleotide uracil (U) replaces thymine. Polymeric DNA and RNA molecules are composed of long strands of nucleotides.

It indicates what elements is composed by and how many atoms of one element are linked to the other.
For example, this is the formula for table salt is:
NaCl
The formula indicates that table salt (sodium chloride) is composed by sodium (Na) and chlorine (Cl) on a 1:1 ratio.
