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.

babunello [35]

Answer:

Ok so trazodone is basically supposed to help you for sleep. Taking it at night would be the best option so that you can sleep peacefully at night. If you take it in the day time, it would be less effective than it is for you at night. I would suggest talking to your doctor more about this rather than taking advice from me, who is nowhere near a doctor. Have a great day/night!!

TEA [102]

Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.

<h3>How brain changes in late adulthood?</h3>

The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.

The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.
