24. The average distance from the sun to Pluto is approximately 6.10 x 10 km. How long does it take light from
bonufazy [111]

The time taken by light to reach pluto will be 5.6 hours.

<h3><u>Explanation</u>:</h3>

The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.

The speed of light was calculated to be 3\times10^{8 m/s. This is the speed of each and every electromagnetic waves.

The distance of pluto from sun is huge. On an average it's 6.1\times10^{9 km or 6.1\times10^{12 m.

So time taken by light to reach from sun to pluto will be 2 \times 10^4 seconds. Or actually 5.6 hours.

The number of possible genetically different gametes for an organism equals
masya89 [10]

The organism can produce 12 genetically different gametes.

<h3><u>Explanation:</u></h3>

The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.

Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.

Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.

So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
