Answer:
Percy Julian's most significant achievement was his work on the synthesis of cortisone and other medicinal compounds from plant sterols. At the time, cortisone was a newly discovered drug that had significant potential to treat a variety of diseases, including arthritis and other inflammatory conditions. However, the only source of cortisone was from the adrenal glands of animals, which made the drug expensive and difficult to produce in large quantities.
Julian's work involved developing a method to synthesize cortisone from soybeans, a process that had never been achieved before. This was a major breakthrough that not only made cortisone more widely available but also paved the way for the synthesis of other important medicinal compounds. Julian's work on steroid synthesis also had important implications for the development of the birth control pill and other hormone-based therapies.
Overall, Percy Julian's achievement in synthesizing cortisone and other medicinal compounds from plant sterols was a major breakthrough in the field of pharmaceuticals and had a significant impact on the treatment of many diseases.
true/false. regional metamorphism is a common, widespread type of metamorphism typically associated with mountain building where large segments of the crust are deformed by the collision of two colliding blocks.
Answer:
true
Explanation:
Regional Metamorphism occurs on a large scale, typically involving hundreds of square kilometers of surface area. It is the most widespread of the metamorphic types and is typical of the major fold-mountain belts such as the Appalachians, Himalayas, Alps or Rocky Mountains.
The given statement "regional metamorphism is a common, widespread type of metamorphism typically associated with mountain building where large segments of the crust are deformed by the collision of two colliding blocks" is True because regional metamorphism is a type of metamorphism that occurs in wide areas of the Earth's crust.
Regional metamorphism occurs mainly in areas with mountain-building activity where large segments of the Earth's crust are deformed by the collision of two blocks. Metamorphic rocks are formed when pre-existing rocks undergo profound changes in response to the influence of high temperature, high-pressure fluids, and the passage of time.
Regional metamorphism, in which rocks are subjected to high pressure and temperature, is one of the two types of metamorphism. The process results in the formation of metamorphic rocks. The high pressure and temperature lead to the development of crystals, and the compression of layers causes the rock to become denser.
Regional metamorphism is widespread and can occur in large areas of the Earth's crust, often associated with the formation of mountains. The other type of metamorphism is contact metamorphism. In contrast to regional metamorphism, it occurs only in small areas and is caused by heat from magma chambers or hot igneous bodies.

there is scanty vegetation in the desert. give reason
The plains have little flora. A desert is defined by minimal rainfall, sparse flora, and extreme temperatures. These climatic circumstances are not conducive to plant development. This is why plains have so little flora. (ii) Sahara arid dwellers dress in thick garments. The deserts have sparse greenery due to unfavourable climatic circumstances for the flora world to thrive. The desert has either an extreme hot or extreme frigid temperature and gets little rainfall, making it unsuitable for vegetation growth. The Sahara arid people dress in thick garments. The temperature in the deserts is either very hot and arid or very frigid and dry, making it impossible for vegetation to develop. Rainfall is scarce. HenceAs a result, vegetation cannot develop in dry circumstances. For the most part of the year, the soil is either sandy (in hot deserts) or blanketed in snow (in frigid deserts). The flora of an area is typically determined by two factors: temperature and soil. The desert's climatic conditions are either extremely hot and arid or extremely frigid and dry, making it unfit for plant development in this area.

Given a parcel of air at 40°C and absolute humidity of 35 g/m3, if saturated, what would absolute humidity be?
Explanation:
To determine the absolute humidity of a parcel of air when it is saturated, we need to calculate its maximum water vapor capacity at 40°C, also known as its saturation specific humidity.
The maximum water vapor capacity of air increases with temperature, so we need to use a formula that takes into account both temperature and pressure. One such formula is the Magnus-Tetens equation:
e = 6.112 × exp[(17.67 × T)/(T + 243.5)]
where e is the vapor pressure in hPa and T is the temperature in degrees Celsius.
Using this equation, we can calculate that at 40°C, the vapor pressure of saturated air is:
e = 6.112 × exp[(17.67 × 40)/(40 + 243.5)] = 7.958 kPa
Next, we need to convert this vapor pressure into absolute humidity using the following formula:
AH = (0.622 × e)/(P - 0.378 × e)
where AH is the absolute humidity in g/m3, P is the atmospheric pressure in kPa, and 0.622 and 0.378 are constants representing the molar mass ratio of water vapor to dry air and the ratio of the gas constants for water vapor and dry air, respectively.
Assuming a standard atmospheric pressure of 101.325 kPa, we can calculate that at 40°C and saturation, the absolute humidity of air would be:
AH = (0.622 × 7.958)/(101.325 - 0.378 × 7.958) = 51 g/m3
Therefore, if the initial parcel of air had an absolute humidity of 35 g/m3 and was heated to its saturation point at 40°C, its absolute humidity would increase to approximately 51 g/m3.

Answer:
Harris's models are decentralized, whereas the others cities focus on the CBD (central business district).
Explanation:
The similarity between the multiple-nuclei model and the galactic city model, both developed by Chauncy Harris, is that they both recognize that cities can have multiple centers of activity, rather than a single central business district (CBD). Both models suggest that cities can have multiple nodes of economic activity and that these nodes can be connected by transportation networks.
A difference between Hoyt and Burgess's models is that the concentric zone model developed by Burgess suggests that cities develop in concentric rings, with the CBD at the center and various land uses radiating outwards in a series of concentric circles. In contrast, the sector model developed by Hoyt suggests that cities develop along transportation corridors or sectors, with various land uses aligned along these corridors.
