Which of the following is not an upstream process? Correct Answer Concentration and primary purification of enzymes

Downstream processes are those that contribute to separation or purification of enzymes. Depending on the intended use of the enzyme, different levels purity is required. For example, enzymes used for diagnostic purposes must be separated to a higher purity than bulk industrial enzymes to prevent catalytic activity that provides erroneous results.

In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for the both quantities and chose the correct option. Quantity A: The ratio of speed of boat to speed of stream is 2 : 1, If the boat travels 162 km and come back to starting point in 36 hour. What is the difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream? Quantity B: The speed of the stream is 6 km/hr and the distance travelled by the boat is 60 km. If the boat covered half distance upstream with usual speed and other half with double its speed, then it takes 7.5 hours less time than usual time to go upstream. Find the total time taken by the boat to go upstream and downstream?
If the sum of the total time taken by boats X1 to travel D km each upstream and X2 to travel downstream is 4 hours and the sum of the total time taken by boats X1 to travel downstream and X2 to travel upstream the same distance D km each is 12 hours. Time taken by X2 to travel upstream exceeds its downstream time by t1 hours. Similarly, the time taken by X1 to travel upstream exceeds its downstream time by t2 hours. What is the value of (t1 - t2)?
Consider the following statements related to uplift pressure in gravity dams: 1. A drainage gallery reduces the uplift pressure at all levels below the gallery. 2. A drainage gallery below upstream water level reduces the uplift pressure at all levels below the upstream water level. 3. A grout curtain near the heel reduces seepage and uplift pressure everywhere on the gravity dam whatever the upstream water level. Which of the above statements are correct?
A boat started from a point in a river and travelled a certain distance upstream, after which it turned back and returned to its starting point. If the boat covered the round trip journey in four hours and the net speed of the boat upstream was 20% of that downstream, how much more time (in minutes) did the boat take to travel upstream than what it took to travel downstream?
A boat goes a distance of 28 km upstream and the same distance downstream. It takes 13 hours 20 minutes for this whole journey. If the time taken by it in going 7 km downstream is equal to the time taken in going 3 km upstream, then what is the speed (in km/h) of the boat when going upstream?
A boat can cover 36 km downstream and 16 km upstream in 10 hours. It can cover 3 km downstream and 1.2 km upstream in 48 minutes. What is the speed (in km/hr) of the boat when going upstream?
A boat covers a distance of 160 m in downstream and 96 m in upstream in 14 seconds and also a distance of 140 m in downstream and 128 m in upstream in 15 seconds. Find the time taken by the boat to cross a 100 m port when the boat is moving in upstream where the length of boat is 44 m.
A boat goes 27 km upstream and 33 km downstream in 6 hours. In the same time it can go 36 km upstream and 22 km downstream. How much time will it take to go 36 km upstream and 44 km downstream?
Questions below followed by two quantities. Find the relation between them. The table shows the distance travelled by five different boats upstream, the speed of the boat in still water and the time taken by them to cover the upstream distance. Boats Upstream distance Speed of boat Time taken  A  240 km  15 km/hr  20 hr  B  150 km  10 km/hr  25 hr  C  350 km  20 km/hr  50 hr  D  96 km  8 km/hr  16 hr  E  126 km  26 km/hr  9 hr   Quantity I: Boat B travel 238 km distance downstream in certain time. How much downstream distance boat D will cover at the same time? Quantity II: Boat E travel 722 km distance downstream in certain time. How much downstream distance boat A will cover at the same time?
A boat can go 30 km downstream and 24 km upstream in 2 hours 27 minutes. Also, it can go 10 km downstream and 4 km upstream in 37 minutes. What is the speed of the boat upstream (in km/h)?
