Exact and identical copies are very rare due to the high chance of mutation, whether being inception, deletion, or crossing over. I would say the best answer choice here is D
Answer:
The correct answer would be divergent evolution showing by homologous organs.
Explanation:
In the illustration human arm, the flipper of the dolphin, wings of bat and forearm of frog are shown. All these four forelimbs have a different function, however, these forelimbs are having the same underlying anatomy.
The organs having basic structure and origin, but different functions are known as homologous organs. These organs point towards the same ancestor from these organisms evolved. They show a case of divergent evolution.
When related species become less similar in order to adapt and survive in different conditions, evolution is called divergent evolution.
Thus, these forelimbs provide evidence for divergent evolution.
Answer:
The digestion process will slow down.
Explanation:
Pancreas is located on the abdomen just behind the stomach. Pancreas releases various enzymes that helps in the digestion of proteins, fats and carbohydrates.
The impairment and deficiency of the pancreas enzyme affects the digestion process as the food is not completely digested and broken down into simple amino acids. The improper digestion can cause severe gastric problems in the individual.
Globular proteins are usually spherical in shape and in term of structure, they are folded in such a way that their tertiary structures are made up of polar amino acids which arranged on the outside and the non polar amino acid are arranged on the inside. This arrangement is responsible for the solubility of the globular proteins and the protein structures is responsible for the catalytic functions of these proteins. Fibrous proteins are insoluble in water, the amino acids that made up this proteins are arranged in such a way that they can serve structural functions in the body.
