The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
A frog is an amphibian so it survive both on land and water
Hope this helps:)
B. meiosis produces cells that are used in reproduction.
Because the pole absorbs the heat quite readily, literally sucking the warmth from your tongue faster than your body can supply it. The saliva on your tongue then freezes (provided it is below freezing), with the resulting ice latching onto the flagpole and your very porous tongue.
Hope that helps you w/ ur question:)
La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate.
