This question isn't really finished, but bacterium are unicellular prokaryote.
I hope this helps?.. :S
Answer:
The correct answer is myofibrils
Explanation:
The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.
Answer:
The answer is
<h2>0.002 cubic meters</h2>
Explanation:
To convert it into m³ we use the following conversion
<h3>
</h3>
From the question the value is 2000 cm³
To convert it multiply the value by
1 × 10^- 6m³
That's
<h3>
</h3>
We have the final answer as
<h3>0.002 cubic meters</h3>
Hope this helps you
Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
