The human body is mostly made up of water (H2O), and there is one oxygen atom in each molecule of water. Note that, although each water molecule also contains two hydrogen atoms, the atomic mass of hydrogen (about 1) is much smaller than the atomic mass of oxygen (about 16). Because of this, hydrogen contributes less to human body mass than oxygen

shutvik [7]

The correct answer would be option D, Brown stains on teeth.

Short term effect of tar on the body is the brown stains on teeth.

Explanation:

When tobacco burns, it creates a sticky brown substance. This sticky brown substance is called the tar.

When smokers consume things that contain tar in it, then the short term effect of tar on the body is the stickiness of that brown substance, tar, on the teeth.

Tooth Decay, Increased Blood Pressures and Drooling may be the long term effects of consuming tobacco. Tar is produced by the burning of tobacco which damages the mouth by rotting and blackening of teeth, desensitizing the taste buds and damaging the gums.

Due to excessive consumption of tar, the lungs of the user are damaged in the long run.

The respiratory tract is lined with cells that produce mucus and contain cilia.
Svetllana [295]

Answer:

I agree

Explanation:

In simple terms, your nasal cavity (or nose in laemens terms) is filled with many many little hairs. Your nose also contains glands that produce mucus. Your hairs in the nose filters out the air and the mucus traps debris and bacteria, which forms boogers. Next, your trachea (or your windpipe that leads to the lungs) is lined with mucus and cilia to also trap dust, bacteria, and other gunk that’s in the air to prevent it from reaching the primary bronchioles (the section of the lungs that branch out at the end of the trachea and lead into the alveoli).

In summary, your respiratory system is filled with cilia and mucus to filter the air you breath, and to trap bacteria and other gunk in the air.
