Answer:

D. 0.5 ft

Explanation:

Using the scale :

1 : 4000

This means that an altitude of 4000 feets is represented by 1 unit in the model.

Hence,

1 feet in model = 4000 feet actual altitude

Given an actual altitude of 2000 feets above ground level ;

Feets in the model will be x

1 feet = 4000 feet

x = 2000 feet

Cross multiply :

4000x = 2000

Divide both side by 4000

4000x / 4000 = 2000/4000

x = 0.5

Hence, 2000 feets above ground level corresponds to 0.5 feets in model

bagirrra123 [75]

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.

Charles is an engineer who is evaluating a prototype of an artificial heart. The prototype beats in a synchronized fashion, is h
Scorpion4ik [409]

The correct answer is a structure that would differentiate the hollow heart into chambers to separate oxygenated blood.

The heart has four chambers: two ventricles and two atria. The right atrium gets oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-deficient blood to the lungs.

The left atrium gets oxygen-enriched blood from the lungs and pumps it to the left ventricle, and the left ventricle pumps the oxygen-enriched blood to the body. The right and left atrium are distinguished by a wall of tissue known as the atrial septum, and the left and right ventricles are separated by the ventricular septum.

Did the detergents containing enzymes work better at removing stains than those containing no enzyme? Why or why not?
Mandarinka [93]

Answer:

Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.
