The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The individuals are hence able to survive and reproduce more than those individuals without the mutation. There is, therefore, a genetic shift in the population in favor of the resistant genotype. After generations, the whole population becomes antibiotic resistant.
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
