    13 is C. Amino acids joined by peptide bonds form polypeptides.
    This example represents protein synthesis, where individual amino acids are chemically linked together through peptide bonds to form polypeptide chains. This process is an anabolic process because it involves the creation of larger molecules (polypeptides) from smaller components (amino acids).
    On the other hand, the second option:
    Amylose and amylopectin combine to form starch molecules.
    This example involves the combination of existing molecules (amylose and amylopectin) to form a larger molecule (starch). While it does involve the assembly of larger molecules, it is more accurately described as a polymerization process rather than a strictly anabolic process. Polymerization refers to the joining of monomers (individual units) to form a polymer (a larger molecule).
    In summary, the first example of amino acids joining to form polypeptides is a more direct and representative example of anabolism, as it involves the synthesis of larger molecules from smaller building blocks.

    27 is A. Non-disjunction is a meiotic error where homologous chromosomes or sister chromatids fail to separate properly during anaphase I or anaphase II, respectively. This can result in an abnormal distribution of chromosomes in the resulting gametes, leading to chromosomal mutations in the offspring.

    Sir isn't 6 mitochondria? I asked because of the endosymbiotic theory which states that mitochondria existed as a prokaryotic cell that invaded a eurokaryotic cell. Prokaryotes don't have a true nucleus so I don't understand why ribsomes is the answer

    • @science_exam
      @science_exam  Год назад +2

      Remember that prokaryotes respire anaerobically. Hence no need for mitochondria. They produce ATP on the surface of their cells. Please note that most of them are faculative aerobes.
      Common structures to both are: plasma membrane, cytoplasm, ribosomes and DNA.
