Exoskeleton
Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,

Answer:
<h2>1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low),</h2>
Explanation:
HCT is calculated as:
HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100
1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT ranges from 38 to 46% (some sources claim 34.9-44.5%).
*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.
Total blood volume = Packed cell volume + plasma volume.
Answer:
c. The starch stayed in the bag and the iodine leaked into the bag and the reacted with it, turning the solution black.
Explanation:
According to the given information, the solution inside the dialysis tubing has starch while water present outside has iodine. The color of the water present outside the dialysis tubing does not change which means that starch did not leak out of the bag and stayed in the bag itself. On the other hand, the starch solution present inside the bag turned black representing the fact that iodine entered the bag. The reaction of starch with iodine produces a blue-black color.
