Answer:
they are the same
Explanation:
since one mole is 6.022×10^23 atoms, one mole of silver is 6.022×10^23 atoms and one mole of tin is 6.022×10^23 atoms. so one mole of tin has the same number of atoms as one mole of silver
The priority after administering is to assess fetal heart
rate. After administering an opioid to a laboring mother, the main concern is
to evaluate the effect on the fetus. Opioid administration can cross the
placental obstruction with signs as well as measuring heart rate and
variability. Subsequently after birth, there may be a reduction in attentiveness.
Maternal factors of a reduced blood pressure, constipation and dry month are of
a lesser importance.
B. specific - meaning it is only able to catalyze a reaction with a certain molecule
<h2><u>Full Question:</u></h2>
In the alveolus pictured above, a disease or injury to which structures would reduce the ability of oxygen to diffuse from the alveolar space to the capillary?
A. A and B
B. B and C
C. B and D
D. A and D
<h2><u>Answer:</u></h2>
The correct answer is option D.
<h3><u>Explanation:</u></h3>
Alveoli is defined as the unicellular thickened sac like structure of lungs which helps in exchange of gases in lungs. The exchange membrane of lungs comprise of three structures -
A. The epithelium cells of Alveoli,
B. The basement membrane of alveolar epithelium,
C. The endothelial layer of blood capillary.
The red blood cells described here won't cause any problems to the diffusion of gases from alveolar cavity to blood. The structures mentioned here as the type 2 cells of Alveoli which secrete lecithin, a surfactant which releases the surface tension of Alveoli. This compound prevents the Alveoli from collapsing and helps in diffusion of gases. The other structure mentioned here as D are the alveolar epithelium which is the unicellular thickened membrane of Alveoli, helping in gaseous exchange.
