Answer:
B. "Telophase"
Explanation:
The chromosomes are at opposite poles, the nuclear envelope is reforming and the cell is getting ready to divide, the next phase is Cytokinesis.
Hope this helped.
No muscle contraction will be observed.
<h3>What is the effect of calcium concentration on muscle contraction?</h3>
The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.

Answer:
Explanation:
The Spinal Cord starts at the brain stem and goes to the tail bone.
Cytochromes:- They are iron containing hemoproteins that serve many cellular functions including energy production, steroid biosynthesis, and degradation of toxins.
Cytochromes occur in all organisms except a few obligate anaerobes. They are structurally similar among organisms. These are proteins to which one to two tetrapyrrole rings are bound. These tetrapyrroles are very similar to the chromophores of chlorophylls in plants. However, chlorophylls(in plants) contain Mg++ as the central atom in the tetrapyrrole, whereas the cytochromes(in aerobic animals) have an iron atom (Figure).
