The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state. The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle. This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle; some cell types (such as neurons and heart muscle cells) when they reach maturity (that is, when they are terminally differentiated) become post-mitotic (enter the G0 phase), and perform their main functions for the rest of the life of the organism. Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.
Answer:
Theory: <u>A theory is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.</u>
Some stimuli act as attention-getting stimuli due to their physical characteristics; others, due to their meaningfulness, act as attention-holding stimuli.
For example, somebody's physical appearance, of a person who is attractive, is used as an attention-getting stimuli, but their psychological qualities are what hold your attention due to their meaningfulness.
Answer:
<em>a. What is the significance of the rainfall? </em>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.
<em>b. The etiologic agent of the disease is </em><em>Coxiella burnetii</em>
<em>c. This is an example of</em> a zoonosis
Explanation:
Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is <em>Coxiella bunetti</em><em>.</em>
- 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 <em>Coxiella burnetii</em>. 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.
