5 0

The xylem is the structure of the plant that is responsible for transporting water from the ground up to the different parts of the plant. It is composed water, inorganic ions, and a number of organic chemicals.

Xylem tissue is found throughout the plant because not only does it transport water, but it also transports the nutrients that the plant needs for different processes. Aside from being responsible for the transportation of materials, the xylem is also used to replace water that was lost during photosynthesis and transpiration.

Answer:

a. What is the significance of the rainfall? These bacteria resist desiccation, and its dispersion is favored by winds. A decrease in rainfall means a dryer environment, which the bacteria can resist and makes it easier for the cell to be carried somewhere else by winds.

b. The etiologic agent of the disease is Coxiella burnetii

c. This is an example of a zoonosis

Explanation:

Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is Coxiella bunetti.

Zoonosis: Referred to as the infectious diseases that are naturally transmitted from animals to human beings. Among zoonotic pathogens, there are bacteria, viruses, or parasites. They propagate by direct contact, water, and wind, among others. These diseases represent a global importance problem due to the close ties with animals. Zoonotic diseases increase even more as human being keeps dispersing and invading natural wild environments to raise cattle and farm, among other activities.

The etiologic agent is the element that propitiates the origin and evolution of a disease. Many bacteria and viruses might be considered to be one of the most common etiological agents.

Populations in contact with goats, sheep, and cattle, use to have a positive result for antibodies against Coxiella burnetii. This bacteria is transmitted to humans orally and by inhalation. The microorganisms resist extreme conditions and are highly infectious. The inhalation of only one cell can produce an important infection in the host. It resists desiccation and any other environmental degradation. They can persist for several months and be transported by winds to farther places. This makes it even more difficult to determine the epidemiologic origin.
