The tick is considered the vector in the chain of infection.
Generally, vector organisms are organisms that are capable of transmitting disease pathogens from infected organisms to uninfected ones either directly or indirectly as a result of their activities.
Ticks are parasites that feed on the blood of vertebrate animals such as deers and humans. When they feed on the blood of animals with certain infections, the pathogens for such infections are sometimes carried in the guts of the parasites and these are transferred to the bloodstream of the next animal that would be their host.
A good example of this is Lyme disease.

Arteries
Explanation:
There are three main types of blood vessels: veins, arteries, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body parts. Veins pick the deoxygenated blood and deliver it to the heart to be oxygenated.
Arteries are the blood vessels with thick walls and no valves. Blood is pumped with higher pressure from the heart into arteries. The pulmonary artery is the only exception that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
Answer:
<u>D) the nucleic acid (either DNA or RNA)</u>
<u />
Explanation:
Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.
The nucleic acids are made up of nucleotides. These are genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).

Water that forms from a mixture of heat and cold (condensation)
The sun heats up the water and it turns to vapors and goes into the air
