A vector of a zoonotic pathogen differs from a host of the pathogen in that it is not affected by the pathogen.
<h3>What are vectors and pathogens?</h3>
Vectors are organisms which serve as carriers of disease-causing organisms known as pathogen. Vectors usually serve as transport or transit mechanisms by which diseases spread.
Pathogen are organisms that cause disease. A zoonotic pathogen is a pathogen that can move from non-human animals to humans.
The vector of a zoonotic pathogen differ from a host of the pathogen in that the vector is not affected by the pathogen and the vector is also non-human.

The answer to this is the Immune System.
The Immune system is made up of a network of cells and tissues and organs that work together to protect the body. The white blood cells (also known as Leukocytes) is part of the immune system, they help destroy disease causing organisms or substances.
That is why when you fall ill and like a few days later you are all better, that is because of the immune system.
Sometimes when somebody has a weak immune system they fall ill more easily and could die because the bacteria that makes you sick isn't being destroyed by the immune system. Sometimes the person has to go to the hospital for treatment and some medications that can help support their immune system.
Hope this helped :)
Have a great day
Oxygenic photosynthesis works as a counterbalance to breathing by taking in the carbon dioxide produced by all breathing organisms and reintroducing oxygen to the atmosphere.
Answer:
<h2>There are two kinds of digestion;
</h2><h2>i) Mechanical and ii) chemical digestion. </h2>
Explanation:
There are two kinds of digestion;
i) Mechanical and ii) chemical digestion.
Mechanical digestion involves physically breaking down the food into smaller pieces. It begins in the mouth as the food is chewed.
In the Stomach
The stomach is a muscular sac with three important functions:
i) It mixes and stores food until it can be further digested.
ii) It secretes chemicals that help break the food into more digestible forms.
iii) It controls the passage of food into the small intestine.
Chemical digestion involves breaking down the food particles into simpler nutrients that can be used by the cells.
In stomach, chemical digestion of mostly proteins occurs Secretions from the stomach lining consist of about two liters of HCl, pepsin, and other many fluids that make up gastric fluids. The fluid is acidic and it helps kill bacteria and many other pathogens. It also produced by the stomach lining usually keeps the acids from damaging the lining. If no mucus or too much acid is produced, peptic ulcers form.
