Answer:
The arrangement of thin and thick filaments in myofibril.
Explanation:
Myofibril is defined as the basic rod like structure present in muscle cells. They are made up of long proteins including titin, actin, and myosin, and other proteins are helping them to hold together. The organization of these proteins are thin, and thick filaments which is known as myofilaments.
Thin filaments: Contains the actin protein which is coiled with filament nebulin.
Thick filaments: Contains the myosin protein. It is also known for force generation.

<span>Lymph node can be described as kidney shaped
organ of the lymphatic system and of adaptive immune system that can be found
throughout the body. The major site of lymph nodes is B and T lymphocytes and
other white blood cells. However, lymph
node associates with follicular dendritic cell in the B cell follicle and
fibroblastic reticular cell in the T cells cortex.</span>

just took a test with this question, positive this is the answer
Two main factors that must be taken in consideration are temperature and the pH level.
The temperature shouldn’t be too low as it slows down the rate of reaction, meaning that the enzyme will work slower, but also not too high as it will cause the enzyme to denature (stops working as it should).
The pH level is pretty much the same, shouldn’t be not too low nor too high.
Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.
