Why is the shape of a protein one of its most critical characteristics?
ValentinkaMS [17]

Protein becomes denatured and cease to perform the work if structural changes occur because protein is highly specific in its function. It is stated that the function of the protein is determined by its structure. The proteins are the product of the continuous process of replication, transcription, translation and post-translational modifications. The information stored in it highly specific.

Protein binds with other molecules and perform various physiological functions as it has specific complementary attachment sites, the alteration in the structure would not let it bind to the target and hence desired result will not come out.

C. Adaptation.

D. Speciation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

A. Charles Darwin: he developed the theory of natural selection based on certain evidences. Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

B. Homologous structure: it involves similar anatomical structures that are having common ancestry or from the same lineage.

C. Adaptation: it is an inherited trait that allows individuals to survive better.

D. Speciation: it is an ecological and biological process through which new species are formed due to isolation.
