It is true that the major ways people are exposed to toxins are by ingesting them, inhaling them, injecting  them, or absorbing them through the skin.

<u>Explanation:</u>

Toxins can enter in four various ways into our body often referred as "route of exposure". It is one among many factors affecting toxicity.

Inhalation: When the toxin is a gas, it is usually absorbed into the body by inhalation. Inhalation of toxins may cause respiratory and lung damage. Eg: cigarette smoke

Absorption: If a toxin enters the human eye or skin, it can be absorbed into the bloodstream. This is called absorption. The skin can prevent some toxins from entering the body. For example: work stations (gas stations) where people work with toxins

Ingestion means that the person has ingested the toxin. Some chemicals cannot get into blood from digestive tract. For example: drinking contaminated water.

The injected toxin enters the body when the person carrying the toxin breaks the skin. Injections can end in veins, muscles or just under the skin. Eg: Botulinum (used to get rid of wrinkles)

In bio-chemistry, poison, a natural or synthetic substance that damages living tissue and has a harmful or lethal effect on the body, regardless of whether it is absorbed, inhaled or injected through the skin.

Answer:

1 A

3 main types of bond are

Ionic bond ( formed due to complete transfer of electron between atoms(

Covalent bond ( formed by mutual sharing of electron)

Metalic bond ( present in the metals due to mobile electrons)

1 B bond in CaO is ionic bond formation in attached image

1 C hydrogen bond with nitrogen is covelent NH3 ammonia is formed because a bond between two non metals is expected to be covalent

More their electronegativity difference between hydrogen and nitrogen is less than 1.7 that makes it covalent

Just remember how many electrons can each sublevel hold.

S=2
P=6
D=10

Since we have 10 for atomic number, we can assume we have 10 electrons

1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)
