zhannawk [14.2K]

Answer:

  • If mitotic cell division is the only way a particular species of a single celled organisms can reproduce it is most likely <u>that prokaryotic cell or the unicellular organism that also included the archea followed the process of mitotic division in order to survive and transmit the right amount genetic materials inside the different levels of generations.</u>
  • As, they were not complex in the cellular machinery which they had but rather went on for an alternative to save energy and reproduce the healthy form of there own species, having the right number of genetic material in them as well just like there parents had.

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.

In a study where participants rated the pleasantness of t-shirt odors, what gene alleles influenced their odor preference
Soloha48 [4]

Major histocompatibility complex are the gene alleles that influenced their odor preference.  

Major histocompatibility complex (MHC), are group of genes found in mammals. Major histocompatibility complex codes for proteins that are present on cells surfaces and assist the acquired immune system to recognize foreign molecules. The primary role of MHC molecules is to attach to antigens obtained from pathogens and show them on the cell surface for recognition by the suitable T-cells.

Look up viruses. Write a short summary of what they are and what they do.
vlabodo [156]

Answer:

Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.
