Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
The correct answer is iron.
The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.
After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.

Explanation:
The thyroid gland uses iodine from food to make two thyroid hormones that regulate the way the body uses energy. The parathyroid glands are four tiny glands located behind the thyroid gland. The parathyroid glands produce a substance (parathyroid hormone) that helps control the amount of calcium in the blood.
