the earths crust because it is the first layer of the earth
Answer:
If a nation were to depend on foreign oil, if there were be an natural event to the country the nation is depending on that would cause a problem such as decreasement of oil or make it hard to export oil it would be hard to find an alternative efficiently. If there was to be a war or feud, or you eliminate an export to the country with the oil, they might stop sending oil.
Explanation:
Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
The cell membrane is composed by a lipidic bilayer. Phospholipids are most likely found in the membrane of a eukaryotic cell.
<h3>MEMBRANE COMPOSITION</h3>
The cell membrane is composed of
- glucans incrusted in between.
The membrane is mostly composed of phospholipids.
<h3>PHOSPHOLIPIDS</h3>
Phospholipids are amphipathic molecules.
They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.
Lipids can easily change places with other lipids by lateral diffusion in the same layer.
They can diffuse transversally to the other layer but not as easily as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Phospholipids are most likely found in the membrane of a eukaryotic cell.

Prokaryotes and eukaryotes package their DNA molecules with protein in structures called chromosomes. A prokaryotic chromosome is circular and resides in a cell region called the nucleoid.
