Answer:
C, basic contractile unit of muscle fiber.
Explanation:
If you read the definition of sarcomere, this is what it says: "<u>A sarcomere (Greek σάρξ sarx "flesh", μέρος meros "part") is the complicated unit of striated muscle tissue. It is the repeating unit between two Z lines. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis</u>."
hope this helps.
Answer:
The results of your testing suggest there was a genetic change in your skin cells
Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.
Examples are: Onion, rhizome (ginger) and daffodil
Explanation:
There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.
Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.
Vegetative propagation can be done artificially also.
*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.
In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).
