Answer:
Both natural selection and genetic drift are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.
Both because having a balanced meal plant is worth alot in the end but if your a vegetarian you would eat only plants as far as being more efficient id say the balanced meal
Answer:
The process of the formation of Urine starts when the blood enters the kidney and is filtered by the nephrons to separate the water from the larger elements that compound it like blood cells and proteins. Then, they go to the blood, and the elements that passed the filtration membrane go to the renal tubule to be moved to the bladder or be reabsorbed in case they are necessary for the body.
Explanation:
The Urine creation process starts with the blood entering the nephron in the kidneys. Then it is filtrated blocking blood cells and large proteins, making only water and smaller elements pass the filtration membrane. Then, cells and proteins, as well as the elements that couldn't pass the filtration membrane, go back to the bloodstream. While the elements that passed the filtration membrane go to the nephron to enter the renal tubule. In this tube some of the components that can still be used by the body are reabsorbed, the rest continues its journey to the bladder.
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.
