When the continents are at the Earths poles, they receive less sunlight.
I’m going for real I haven’t done this because it was hard didn’t get it but now I know // ANSWER -
The white blood cell identifies the toxin produced by the pathogen and creates antibodies to fight the pathogen
1) Independent Variable- I change: the lighting or the dark vs light (Idk if I'm making sense)
Dependent Variable- data being collected: How many ants end up on either side
Hypothesis- If, then statement... Well you can make this up but if you need my help I'll help... Hope this helpsss!!
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
