According to a recent warning from the FDA, grain-free food might be giving dogs a life-threatening heart problem called dilated

cardiomyopathy, or DCM. Scientists interested in studying this link were trying to see if there was a difference in the average blood pressure of dogs on grain-free dog food vs the average blood pressure of dogs on food that includes grains. To minimize variation in subjects, scientists measured the initial blood pressure of 30 dogs while each was still on a grain-free diet, and then took a second measurement 8 weeks after each dog was switched to a diet that included grains.

The pO2 of air in an alveolus is ________________ that of the pO2 in deoxygentaed blood in a pulmonary capillary
Zanzabum

Answer:

The correct answer is a. greater than

Explanation:

The partial pressure of oxygen in alveolus is greater than partial pressure of oxygen in deoxygenated blood in a pulmonary capillary and this concentration difference is important for the movement of air(oxygen) from the alveolus to the pulmonary capillary because gases move from higher concentration to lower concentration.

By this process the oxygenated blood reaches to the heart from lungs and heart then pump this oxygenated blood to other body tissues.The partial pressure of oxygen in alveolus is 104 mmHg and in venus blood is 40 mmHg.

Which of the following is a good example of patternicity?
Ket [755]

Of the examples listed, and given the definition of patternicity, we can say that the best example is that of the Constellations. Option A is correct.

Patternicity is a tendency displayed by most humans. It is the tendency to perceive patterns and relate them to otherwise unrelated objects. Some examples of this that are seen commonly are:

  • Constellations
  • Seeing figures in clouds
  • Comparing birthmark shapes to everyday objects

Constellations are groups of stars that we perceive to form a pattern or figure of some kind. There are many constellations and although they have served navigational purposes among others throughout the years, their very existence is an example of patternicity given that each star is individual and has no relation to one another nor the figures we perceive them to form.
