Answer:
B. removes suspended particles.
Explanation:
The first step in water treatment involves the removal of of suspended particles through the process of coagulation, sedimentation and filtration.
Coagulation process involves the addition of positively charged chemicals to the water. The positively charged chemicals neutralizes the negatively charged particles suspended in the water to form larger particles known as flocs.
The particles are then allowed to settle down through the process of sedimentation after which they are then filtered off in a process known as filtration.
The sun provides light energy to the earth via Solar particles, I think.
Answer:
Since there is no distinction in the measure of the RNA polymerases yet rather their movement, the distinction lies in their structure and not their grouping. Adjustments are made to widen the states of endurance. Thus E. coli would not constrain it's endurance by restricting its development to hotter temperatures. Thus the appropriate response is "the RNA polymerase sub-units of the P. syringe strain most likely have additional adaptability with the goal that they can move all the more openly in colder temperatures".
Answer:
The correct answer is - 3 hours 15 minutes.
Explanation:
Given:
Speed = 768 km/h
distance = 2496
Solution:
Converting speed in km/minutes:
768/60 = 12.8
Now by the formula,
Time = distance/speed
time = 2496/12.8
=195 minutes
converting in hour = 195/60
= 3 hour 15 minutes.
