Answer:
anything contrary to the information provided below
Explanation:
Proteins determine the shape and structure of cells and the direction of almost all vital processes. Protein functions are specific to each of them and allow cells to maintain their integrity, defense of external agents, damage repair, control and regular functions, etc. selective binding to molecules. Structural proteins agree with other molecules of the same protein to cause a larger structure. However, other proteins bind to different molecules: antibodies to specific antigens, hemoglobin to oxygen, enzymes to their substrates, regulators of genetic expression to DNA, hormones to their specific receptors, etc.
Answer:
Due to presence of these structures in ancient as well as modern organisms.
Explanation:
Homologous and vestigial structures are the evidences that show evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.
Mitochondria is a semi autonomous cell organelle, it is able to make its own protein because it has promiscuous DNA which has genes that have instructions to make proteins
