Convection about the city
julsineya [31]

Convection- is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion.

Explanation:

Cities become warmer than their rural surroundings due to buildings, roads and other infrastructure replacing open land and vegetation. “Surfaces that were once permeable and moist,” writes the“become impermeable and dry.”

During the daylight hours, temperatures inside large cities range between 1.8 and 5.4 degrees F warmer than their surrounding areas. At night, city temperatures can be as much as 22 degrees F warmer.

This phenomenon was believed to be the result of concrete and other structures absorbing heat throughout the day and then gradually releasing it at night. But a new study published last week in the journal Nature offers a different explanation: Convection.

How air moves through a city during the day has a greater role in trapping heat, the study claims, than the disappearance of vegetation and the existence of urban structures.

Is he taking any drugs for sexual enhancement or erectile dysfunction!?!?

Nitroglycerin is a vasodilator, which means that it relaxes and dilates (widens) blood vessels; this is a positive effect for coronary arteries, whose narrowing and/or occlusion (blockage) may be the cause of [cardiac] chest pain.
But, other vessels throughout the body also dilate, which can be good in hypertension.
However, a specific class of drugs known as phosphodiesterase-5 inhibitors (PDE-5-I), which includes sex-enhancing drugs for erectile dysfunction (ED), will irreversibly keep body vessels dilated when nitroglycerin is also present in the bloodstream. This can lead to a life-threatening pooling of blood of the arms and legs (extremities) and lower body, keeping adequate blood from reaching the heart, lungs, and brain. This emergency is known as vasogenic shock!
Examples of PDE-5 inhibitors are Viagra, Levitra, and Cialis. [generic names of this class are: vardenafil, sildenafil, tadalafil and avanafil]

How vaping can affect ATP production and cellular respiration?<br> AT LEAST 5 SENTENCES.
Slav-nsk [51]

Answer:

<h2>Vaping decreases the ATP production which will then impair the cellular respiration. </h2>

Explanation:

Vaping decreases the ATP production which will then impair the cellular respiration. It is proven to cause lung inflammation. One example is the use of <em>"cinnamaldehyde</em>" as a flavor in vapes. It has been proven to lower the ATP production. Since ATP is responsible for fueling the cells in the human body in order for humans to do specific tasks, the decreased number will lead into the<em> death of cells</em>. This will then impair the cellular respiration of the human body.

<u>Further Explanation</u>

Vape- This is also known as an electronic cigarette. The action of inhaling and exhaling the vapor in the electronic cigarette is known as "vaping."

Vaping seems to be a controversial issue these days. Many companies claim that e-cigarettes are actually safe. <u><em>However, opponents claim that repeated exposure to vapor causes an adverse effect or a potential risk. </em></u>
