<span>Most vulnerable side is the ventral because in the dorsal side there is the backbone. Most of the harder bones are on the dorsal side. So then the ventral side also known as the belly side is more vulnerable and softer.Sorry I took Forever LOL</span>
Answer:
<u>Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.</u>

When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time. Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.
CH2O5 +603-6CO2 + 6H2O + energy isn't the evidence of conservation of mass in cellular respiration.
Option B
<h3><u>Explanation:</u></h3>
Law of conservation of mass states that mass can neither be created nor be destroyed. And this law holds good for all sorts of chemical reactions except the nuclear reactions.
In case of cellular respiration, one molecule of glucose reacts with 6 molecules of oxygen to produce 6 molecules of carbon dioxide and 6 molecules of water and energy. Now this energy that is produced isn't produced in expense of mass, but in expense of chemical bonds that are present in glucose molecules.
Also if we calculate the number of atoms on each side of the reaction, the number of atoms remain same as well as number of atoms of individual elements also remain same.
