Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
Answer:
1. Endoneurium covers the myelinated or unmyelinated axons. it is a layer of delicate connective tissue that envelops the myelin sheath of each of the myelinated nerve fiber.
2. Perineurium covers fascicles. It is the connective tissue sheath that envelops fascicle of nerve fibers within a nerve.
3. Epineurium covers nerves. It is the outermost layer of dense irregular connective tissue that envelops the peripheral nerve and multiple nerve fascicles.
Water is the solvent of organisms
<span>A. chromosomes
Chromosomes is where the DNA is structurally formed and determined.
Almost all organisms have a chromosome which is a significant unit in a cell of every living thing. In most prokaryotic organisms these chromosomes are just plastered in its cytoplasm without a fully developed nucleus contrary to the eukaryotes.</span>
Chemical properties could be the smell and color, physical could include the shape of the cream and the textures
