Answer: False
Explanation: I took the test :)
The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release.
Answer:
The correct answer is 4,960,000
Explanation:
If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.
So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.
Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).
Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
Answer:
Kindly check attached picture
Quantity measured is DISTANCE
Explanation:
Segment AB = measures uniform deceleration
BC = Constant speed moved by the car
CD = Uniform acceleration
During uniform deceleration: the speed of the body is reduced at a constant rate with time.
During Constant Speed, the car maintains a Velocity which does not increase or reduce at a certain time interval.
During uniform acceleration the speed of the car increases at a constant rate with time.
B) THE quantity measured by the area covered under a speed-time graph is distance :
With speed on the vertical (y-axis) and time on the horizontal (x-axis)
Area of trapezium = 0.5(AD + BC) × height
