humans with the sickle cell mutation suffer from sickle-cell disease which is often fatal. despite that fact, certain areas of a
Stells [14]

In certain areas of Africa, the sickle cell mutation has a high frequency because it confers an adaptive advantage against malaria which is endemic to this region.

<h3>What is natural selection?</h3>

Natural selection is a mechanism that drives evolution in natural populations, which in case we are observing stabilizing selection because it acts to stabilize the frequency of different alleles.

In certain regions in the African continent, the sickle cell mutation exhibits a high frequency since it is able to confer resistance against malaria which is an endemic disease located in this region.

Therefore, with this data, we can see that stabilizing selection acts to increase the frequency of the sickle cell mutation, which is harmful in regions where malaria is not endemic but increased in certain parts of Africa due to the incidence of malaria, thereby being an adaptive trait for these geographic areas.

What is different about normal cell division and cancer cell division?
klasskru [66]

Answer/Explanation:

Normal cell division is a very controlled process.

There are several checkpoints where the cell ensures the cell is:

  • receiving the correct signals to divide
  • that the environmental conditions are favourable for the cell to divide
  • that there is no damage to the DNA.

However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.
