Answer:
C) most of the muscle's energy is produced in mitochondria.
Explanation:
The activities such as running a marathon require aerobic endurance to allow prolonged and sustained muscle contraction for a longer duration (few hours) without fatigue. These activities rely on the production of ATPs in mitochondria through the process of anaerobic cellular respiration.
The process of aerobic cellular respiration produces a large number of ATPs to sustain prolonged muscle contraction. Slow oxidative muscle fibers that contain a large amount of myoglobin and are rich in mitochondria are involved in such activities.
you can put a needle through it and it won't break.
The Answer Is Chemical Comosition
Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells (e.g. egg or sperm), each with half the number of chromosomes of the parent cell. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. Mitosis includes one division, while meiosis includes two.
Explanation:
The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. The primary structure is held together by peptide bonds that are made during the process of protein biosynthesis. ... The sequence of a protein is unique to that protein, and defines the structure and function of the protein.
