<span>The answer is free-market. One view is that a free market is a framework in which the costs for products and enterprises are controlled by the open market and purchasers, in which the laws and strengths of free market activity are free from any intercession by an administration, value setting syndication, or other specialist.</span>
Answer:
Savannahs
Explanation:
Savannahs are usually large areas of open land with few trees. This area is different from deserts because they receive more rain which allows grasses to grow, unlike desserts.
Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.
When there is an increase in temperature with altitude, that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.
So how air circulation behaves during inversion?
So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:
• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.
• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.
• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.
• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.
Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.
Hope it helps! :)
This can be demonstrated by using an acellular environment to observe the 32P label entering phosphatidylethanolamine (PE) molecules by direct exchange.
Phosphatidylethanolamine (PE) is a major lipid component of cellular membranes in a wide range of organisms.
A scientist proposed that the 32P label was entering PE molecules by direct exchange, this can be proved using acellular environment.
In acellular environment, there aren't any bacterial cells to synthesize new PE. So if the 32P is incorporated into the PE in the acellular environment that means the proposed idea in the question stem is correct.
If no 32P is incorporated into PE in the acellular environment, then that means proposed idea is not correct.
Disclaimer: The question is not completed.
A scientist proposed that the 32P label was entering PE molecules by direct exchange (swapping phosphate groups with those found in solution) and NOT through synthesis of new PE by bacterial cells. What experimental modification can show this is NOT the case?
