Answer:

Lucy's respiration rate increases because of the decrease in the atmospheric pressure and the partial pressure of O₂.

Explanation:

As Lucy ascends, the atmospheric pressure decreases. The decrease in this pressure decreases the partial pressure of inspired O₂, which causes less oxygen saturation in the blood. As oxygen is essential for the vital functions of the body, the respiratory rate increases to valance the loss of oxygen. In other words, the oxygen that the body had in one inspiration, now it has to obtain with multiple breaths. The same happens with the CO₂ that Lucy expels from her body.

<h3>What is the connective tissue?</h3>

Connective tissue is one of the types of primary tissues which has the function of supporting and integrating the rest of the cells since it is the tissue that gives a union of different tissue elements that make up the organs.

This tissue helps move nutrients to the cells they contain in order to give them nutrition, they can also transport other types of substances. Within the types of connective tissue are cartilage, adipose tissue and blood.

Therefore, we can confirm that the tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
