Answer:
The best answer to the question: The Z disc forms the end____ of a sarcomere, would be: the end border, or the point where sarcomeres join, within a muscle fiber.
Explanation:
Concretely, a Z disc is the boundary line that divides sarcomeres within a muscle fiber. They are the bordes between sarcomeres and they contain the most important molecule, actin, which forms the thin filaments essential for muscle tissue movement. This actin molecule, present along the Z discs, under the correct stimulation and circumstances, will bind to myosin and thus movement will be possible.
Answer:
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Explanation:
Mutations can be any but id say all besides always harmful or all of the above if that’s a choice
The influx of positive charges makes the membrane potential more positive and is known as depolarization.
<h3>
What makes the membrane more positive charge ?</h3>
The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.
<h3>What does polarization mean?</h3>
The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).
<h3>How membrane is affected by polarization and depolarization?</h3>
At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).
