Answer:
Decreasing the diameter of the channel by removing aa's. Since Na+ is chemically similar to K+, one can assume the difference must be due to the size of the atom. The K+ ion is larger than the Na+ ion, so reducing the diameter of the channel can allow Na+ to enter while preventing K+ entry. This explains clearly and perfectly how reducing the diameter reduces the
transport of K+ in favor of Na+ transport.

Answer: The density would be p = 19.3 g/cm3 because
Explanation: because if you calculate density the formula would be d = <u>m</u>
v
so just use the values giving and you get the answer by plugging the 96.5 mass then 5 for the volume then divide it.
C. A tree Trees can turn light into chemical energy using photosynthesis.
Answer:
A. No; B. yes
Explanation:
A. Mass
The balloons contain different gases, which will have different densities.
Mass = volume × density
m = V × D
However, the volume is the same for all three balloons.
Thus m = kD
And the mass of the gas is directly proportional to the density.
Since the density varies, the mass varies.
B. Number of molecules
This is Avogadro's Hypothesis:
At the same conditions of temperature, equal volumes of gases contain the same number of molecules.
