Answer:
Evolution is a change in the inheritable phenotypic characters within a population occurs through successive generations.
Explanation:
Evolution is a change in inheritable characters of population during a period of time by means of natural selection. These changes in phenotypic characters brings the formation of new species. Darwin's theory consists of three categories,individuals within a group are variables, variations are inheritable,all individuals with variables survive.
According to Darwin's theory states that survival is based on selective mode like particular phenotypic characteristics or behavior given to some individuals who are able to survive in a particular environment.
From these observations, the researcher may use bottom up approach to suggest that the blood clotting properties of COX-2 inhibitors lead to heart failure.
Heart failure occurs when the heart muscle doesn't pump blood as well as it should. Blood often backs up and causes fluid to build up in the lungs (congest) and in the legs. The fluid buildup can cause shortness of breath and swelling of the legs and feet. Poor blood flow may cause the skin to appear blue (cyanotic).

Answer:
Mutations that activate the kinase portion of the receptor result in a receptor that is constantly phosphorylated. This causes constitutive activation of downstream signaling and the resulting cell growth and proliferation
Explanation:
The epidermal growth factor receptor (EGF receptor) is a type of receptor tyrosine kinase that recognizes and binds different ligands (including the Epidermal growth factor), which triggers its dimerization through the interaction of the extracellular domains. In humans, several mutations in genes encoding receptor tyrosine kinases have been associated with cancers. It is for that reason that mutated receptor tyrosine kinase genes are well-known oncogenes. Moreover, mutations in several receptor tyrosine kinase genes that lead to constitutive activation by phosphorylation have also been identified. In this case, it is expected that a mutation in the EGF receptor leads to constitutive phosphorylation of the mutant protein, constitutively activating downstream signaling.
