6 0

Answer:

C. Systemic arterioles respond to a decrease in PO₂ by dilating, but pulmonary arterioles constrict in response to decreased PO₂.

Explanation:

In the arterioles, vasoconstriction is a response to high oxygen while vasodilation is a response to carbon dioxide and low pH. However, in the pulmonary arterioles, vasoconstriction occurs as a response to low oxygen and this mechanism is called hypoxic pulmonary vasoconstriction (HPV).

2. Prometaphase I

3. Metaphase I

4. Anaphase I

5. Telophase I

6. Cytokinesis I

Meiosis II

1. Prophase II

2. Prometaphase II

3. Metaphase II

4. Anaphase II

5. Telophase II
