Flatworms can be cut in halfcreating two individuals by binary fission. Binary fission is a type ofasexual reproduction in which the offspring has the same features andcharacteristics of the parent. During binary fission, the DNA replicates intotwo and goes at the end of each membrane. And then the cell membrane divides intotwo daughter cells. Then cytokinesis follow.
Answer:
If you think about you're cutting and Flatworm in half. Flatworms don't naturally divide/create new individuals by binary fission. So, the answer would be c) fragmentation; based on the fact that you are the one cutting the Flatworm, not the other way around.
Answer: Option (d) is the correct answer.
Explanation:
When my friend made fun of me for loosing the race then obviously this thing left me with no confidence. Also, I would feel shame for losing.
As a result, i have decided not to run anymore.
This represents an example of negative peer influence as the comments or fun made by my friend has made me come to a negative decision.

The mass of each car is the same so car D will take the longest time to come to a full stop. Hence, option D is correct.
In mechanics, acceleration is a unit used to describe how quickly the velocity of an object varies in relation to time. The direction of the net force acting on an object determines its acceleration.
Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is another vector quantity. Acceleration is defined as the change in velocity vector over a time interval divided by the time interval.
According to the question, we want to determine which automobile will take the longest to fully stop because we know that each one has the same mass and the same velocity. Here, we can assume that all the vehicles slow down uniformly, thus the vehicle traveling at the maximum speed will take the longest to come to a complete stop.

Answer: Car D.
Explanation:
We know that each car has the same mass, and knowing the velocity of each car, we want to know which car will require the longest time to come to a full stop. Here we may assume that all the cars decelerate at the same rate, so the car with the highest speed is the car that will take the longest income to a full stop.
The answer is car D, which velocity is 895 m/s.
b. Elements
c. Molecules
B. 1,200 m/s
C. 1,800 m/s
D. 1,500 m/s
Answer
D. 1,500 m/s
Explanation
the wave equation states that,
V = λf
Where V ⇒ Velocity
λ ⇒ wavelength
f ⇒ Frequency
F = 1/T
Where T ⇒ period
F = 1/0.006
= 166.667
∴ V = 9 × 166.667
= 1,500 m/s
