Light travels extremely fast through the air, 300,000,000 m/s. Sound travels much slower, 343 m/s through air. Therefore we can see light in an instant, but it takes a while to hear thunder.
Explanation:
When you compare the numbers (speed of light vs speed of sound) you understand that light is 10^6 faster in speed that sound. When lightning occurs at a greater distance from the observer, this difference in speeds in more perceptible because the two different waves would have to travel greater distances to the observer and the relative differences in speed become increased.
Remember however, that sound travels in a medium while light waves do not require a medium because they are electromagnetic waves. In a vacuum, therefore, you would observe the lightning but never the sound.

The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.

Answer:
96
Explanation:
This is genetic drift question, we can tell because the variable here is the population size. The probability of an allele of getting fixed is determined by its initial frequency, which is actually the probability of the allele of being fixed. So we need to calculate the initial allele frequency of this mutation:
Mutation allele frequency = # mutation alleles / total # of alleles = 1/24 = 0.04%
That is the probability of this allele to get fixed, so the probability of this allele getting eliminated is:
Elimination probability = 1 - fixing probability = 1- 0.04 = 0.96%
Answer: The probability of this allele getting eliminated is 96
