The karyotype of one species of primate has 48 chromosomes. In a particular female, cell division malfunctions, and she produces
Rom4ik [11]

Answer:

E) Either anaphase I or II

Explanation:

Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.

On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.

Why does geographic isolation cause speciation?
zimovet [89]

Answer:

A. It allows two populations to evolve separately.

Explanation:

Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.

We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.

B is incorrect because it doesn’t apply.

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.
