Answer:
Because your final periods can be irregular, menopause is confirmed 12 months after your last period. It is not normal to bleed or spot 12 months or more after your last period. Bleeding after menopause is usually a sign of a minor health problem but can sometimes be an early sign of more serious disease.
Answer:
It is well known that DNA is more important than RNA for Evolution. As the DNA contains the genetic and heridetary which is responsible for Continuity of the generation after generation. So, that's why. The DNA is more important than RNA for Evolution.
Explanation:
Anaphase, they line up at the equator during the previous phase, Metaphase
Answer:
<u>the bottleneck effect</u>
<u />
Explanation:
Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.
Some mutations or alleles may become extinct from the population.
<u />
Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.

The movement is kind like Earthquakes because at divergent boundaries, lithospheric plates move apart and crust is created. At convergent boundaries, lithospheric plates move together in collision zones where crust is either destroyed by subduction or uplifted to form mountain chains.
