The answer is A) 2 m/s because to calculate the speed, you do distance divided by time. This means that 8/4 = 2.
The major difference between the particles in a liquid and a gas of the same substance at the same temperature is that; the particles in the gas are moving faster than the particles in the liquid.
There are three states of matter which are;
The difference between the states of matter lies in;
- Degree of inter molecular interaction between molecules in a given state of matter
- Kinetic energy of the molecules in a given state of matter.
Liquid molecules or particles are slower than gas particles because liquid particles have a greater degree of inter molecular interaction than gas particles.
So, the difference between a liquid and a gas at the same temperature is that; "the particles in the gas are moving faster than the particles in the liquid".

Answer:
Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
Explanation:
Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment. All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.
Hence, option A is correct.
