Answer:
A :an atom seeks to fill its outer shell of electrons
Explanation:
Reactions between atoms occur due the desire of an atom to fill their outer shell electrons.
The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like those of the noble gases.
- The various interatomic interaction which leads to chemical reaction is in a bid for the atoms to be isoelectronic in the outer energy level with the noble gases.
- This is achieved by gaining, losing or sharing of electrons.
If left untreated, the probable lead for hypertension to an
individual is kidney failure. It is because the blood pressure is associated
with the kidneys because the nephrons of the kidneys are being supplied with
the blood vessels dense network and also because of the blood that flows
through it, when there is a presence of hypertension and left untreated, it
could cause the kidney to weaken or harden—causing kidney failure.

The role of the Golgi body or Golgi apparatus is to package the proteins in vesicles and target it to their respective place of function. Example, the receptor proteins that are synthesised in the Endoplasmic Reticulum will be sent to the Golgi body for its packaging into the vesicles that bind and fuse with the cell membrane. The targeting is done by the special set of markers present on the secreted vesicle. All the eukaryotic cells have a Golgi apparatus. When chemical treatment is done to stop its functioning, the cell stops functioning and eventually dies due to the hampered targeting of proteins to the various organelle. On the other hand, prokaryotic cells lack Golgi body as the cell size is small enough to allow for the synthesised protein to move by diffusion to its target. Hence no effect will be seen when prokaryotic cells are treated with that chemical.
Answer:
Chemical properties are tested on not because of their color or their appearance but how they will react to certain tests. Such as; is it flammable? Could it be toxic? Physical properties are tested on and observed because of the texture, the color, smell and etc.
Hope this helps!
