Answer: A low pCO2 indicates respiratory alkalosis which may be primary or secondary to a primary metabolic acidosis. Bicarbonate is calculated from measured [H+] and pCO2 values. A high standard [HCO3- ] indicates either primary metabolic alkalosis or a compensatory response to a primary respiratory acidosis.
Explanation: an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis. The higher the minute ventilation, the more exchange and loss of PCO2 will occur inversely.
Answer: 2
Explanation:- Mechanical advantage is the ratio of the output force to the input force.
Mechanical advantage=
Given:
Input force = 320 N
output force= 640 N

The process of <u><em>meiosis </em></u>increases genetic variability as it produces gametes for sexual reproduction
Explanation:
More complex organisms, including humans, produce specialized sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths.
Answer: D. Quantitative Observation.
Quantitative observation is the usage of your senses (smell, sight, touch, etc) or measurements to observe the results.
