A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.

<h3>Hypothesis and scientific method</h3>

A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.

Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.

In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.

Which description is an example of codominance
xxMikexx [17]

Answer:

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

How did creating a greenbelt affect sprawl? Why do you think this happened?
scZoUnD [109]
The OECD found that the responsiveness of housing supply to demand in the UK was the weakest among developed countries, due in large part to green belt policies. The green belt concept was first introduced for London in 1938 before the 1947 Town and Country Planning Act enabled local authorities to designate the status themselves. The policy was introduced to contain urban sprawl following huge post-war housing developments, and expanded greatly between 1951 and 1964. Since 1979, the green belt has doubled to cover 13 per cent of land in England (while only 2.3 per cent is covered by buildings).
