Answer:
The correct answer will be option-B (Semi-synthetic)
Explanation:
Chemical drugs can be synthesized through many ways on the basis of which they can be categorized:
1. Natural Drug: The drug prepared from the natural extracts.
2. Synthetic Drug: The drug is synthesized by chemical reactions.
3. <u>Semi-synthetic Drug</u>: The drug which is neither completely natural nor synthetic that is they are prepared from the natural extracts by modifying them.
Since in the given question, the drug was prepared by the converting side chain to the hydroxyl group of the antimicrobial drug therefore it is considered as the semi-synthetic drug and Option-B is the correct answer.
 
        
             
        
        
        
Answer:
Fibrinogen
Explanation:
Fibrinogen is one of the proteins present in the blood plasma. It makes 7% of the plasma proteins. During the process of blood clotting, the active thrombin enzyme serves to convert soluble fibrinogen into insoluble fibrin. These insoluble threads of fibrin form the clot. Both thrombin and fibrinogen are produced in the liver. If fibrinogen is less than 4%, the process of blood clotting will be disturbed due to the production of insufficient threads of fibrin. 
 
        
             
        
        
        
Answer:
The foramen magnum was not located at the bottom of the skull
Explanation:
The foramen magnum is a large hole or opening found in the base of the skull  through which the spinal cord passes.
The position of the foramen magnum is important since it allows the skull to balance on the body hence essential for posture.
Humans are bipedal and Howler monkeys are quadrupedal hence the positioning of the foreman will be different.
That is how the skull found was realized it was not human
 
        
             
        
        
        
The water cycle is a parameter of the hydrosphere that always remains constant. Life on Earth and its sustenance is possible because of this cycle. The continuous evaporation, condensation, and precipitation of water provides for the many processes involved in Earth's natural surroundings. Without the water cycle, life would cease to exist.
        
                    
             
        
        
        
Region of the World                             Percentage    Value in Metric tons
North America                                          17                  23,332,500
Asia                                                          52                  71,370,000
Africa                                                          3                    4,117,500
Europe                                                     18                  24,705,000
Latin America and the Caribbean              8                  10,980,000
Oceania                                                  <u>   2</u>                <u>    2,745,000</u>
                                                               100                137,250,000
We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.
Asia uses 71.37 million metric tons. 
In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.
