Answer:
The correct option is C. Motor neuron does not fire action potentials
Explanation:
During contraction, the motor nerve passes down an action potential. A neuromuscular junction is formed by the motor neuron which stimulates the entry of calcium ions. The calcium ions bind to structures called as troponin which stimulates the binding of the filaments, actin and myosin. The filaments begin to contract by using ATP.
During relaxation, the action potential is stopped. Calcium is taken back into the sarcoplasmic reticulum. As a result, actin and myosin filaments do not link and hence, the contraction is stopped.
I believe:
Restriction Enzymes, and DNA Ligase
These enzymes cut n paste DNA, to produce a molecule of recombinant DNA, such as the red fluorescent gene used in ABE. These enzymes are used in the first step of DNA Cloning.
Hope this helps!!!!!
The brain i think that is correct
Answer:
Algae and fungi do not have cell wall and many other organisms do not have a cell wall.You can check it out on google for more examples.
Explanation:
<span>While Acid fast bacteria retain carbol fuchsin after acid-alcohol treatment, non- Acid fast bacteria are decolorized by acid-alcohol.
Bacteria of genus mycobacterium are best stained using acid-fast method. A mixture of Phenol and fuchsin is carbol fuchsin. In acid-slcohol, acid is hydrochloric acid.</span>
