Determine whether each occurrence is a result of short-term or long-term change. Sort each one to the correct category.

speciation

Short-Term Change

Long-Term Change

adaptation

loss of habitat

extinction

forced migration

Adaptation and extinction occur as a result of long term change whereas loss of habitat and forced migration results of short term change.

Explanation:

Adaptation and extinction occur as a result of long term change in the environment whereas loss of habitat and forced migration is a result of short term change in the environment. Adaptation occurs in the organism as a result of climate change because when the climate change occurs some organisms are extinct due to intolerance of the change environment whereas some organisms adapt the environment by making some changes its physical structure in order to survive. Loss of habitat and forced migration occurs due to sudden big change in the environmental conditions such as flooding and volcanic eruptions.

AB : BO

2 : 2

Explanation:

             A          O    

B          AB        BO

B          AB        BO

Because only two alleles can be found in an individual, there are six possible combinations i.e. AA, AO, BB, BO, AB and OO. If a man is heterozygous for blood group A marries woman who is homozygous for blood group B then 2 children will be blood group AB and 2 will have BO.
