Answer:
The alveolar walls and capillary walls share a membrane. That's how close they're getting. This allows oxygen and carbon dioxide to readily pass from the respiratory system to the circulation. Oxygen molecules bind to red blood cells as they return to the heart.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
If V = 2V and p = 2P
Then,
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
As for this question, the answer would be B. kidney.
GU system or what they call as the Genitourinary system and may also be referred to as urogenital system is the system of both the reproductive system and the urinary system. They can be classified together into one system due to their immediate proximity, their origin during the embryological stages, and also the usage of a common organ. Rectum would be part of the excretory system. Lymph nodes would be of the lymphatic system and the adrenal gland would be in the endocrine system.
