jeka94

Answer:

Plate boundary zones.

Explanation:

  • Plate boundary zones are the interaction between adjoining plates where they clash, pull separated or slide past each other.
  • These newly created zones can be a long stretch from few kilometers to hundreds of kilometers.
  • It is the movement between two plates and the distortion that come about in the boundaries of the zone between the plates, which has given birth to New Zealand's geography which we see it today.
  • The distortion and mashing caused by the hit of the two great plates have created mountain ranges throughout the country.

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.
