The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
pav-90 [236]

Answer:

d. alveolar ventilation rate

Explanation:

Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.

IrinaVladis [17]

Explanation:

Answer:

For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.

Which of the following is not a characteristic of cancer cells?
julia-pushkina [17]

Answer:

B. They have a single small nucleus.

Explanation:

The presence of large nucleus is a characteristic feature of cells that frequently undergo cell division. Cancer cells are characterized by uncontrolled continuous cell division even when the new cells are not required by the body.

This leads to the formation of benign or metastatic tumors. To undergo continuous cell division, the cancer cells have a large nucleus. The nucleus of the cancer cells is mostly hyperchromatic and distinct due to higher nuclear to cytoplasmic ratio. It allows these cells to exhibit the uncontrolled cell division.

The cells that respond to changes in blood gas concentration and generate the respiratory rhythm are found in several nuclei in
levacccp [35]

The answer is; medulla oblongata and pons.  

In this region of the brain, there are chemoreceptors that can detect changes in the pH of the blood. These are called central chemoreceptor. There are also chemoreceptors in the arteries called peripheral chemoreceptors. When these chemoreceptors detect a drop in the blood PH (due to increased dissolved carbon dioxide in the blood), the depth and rate of breathing is increased in the lungs.
