Answer: D. All of the above.
Explanation:
The mass remains the same given that the number of air molecules remain the same and none did escape into the atmosphere.
As heat is being absorbed by the air molecules, they vibrate more vigorously and the electrostatic forces of attraction between the molecules weaken and they become further apart. Hence there is lesser number of air molecules per volume, indicating that density has decreased.
Answer:
2) liver
Explanation:
the bloods transports the lactic acid to the liver to be converted into glycogen
Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion
