So by looking at the seismic waves from earthquakes the scientist learned about the crust and the mantle but they also learned about the outer and inner core. To do this you have to look at a different kind of waves, the S (secondary waves) waves that also get released by an earthquake.
Cells are limited in size because the outside also known as the plasma membrane must transport food and oxygen to the inside of the cell. This can be represented by what is known as the surface to volume ratio.
Answer:
about succession? it's c.
I believe the answer is C. Nucleus, Cell Wall, Cell Membrane
If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.
Types of passive transport include diffusion and osmosis, both of which involve moving down a concentration gradient and thus not requiring energy.
Active transport moves up the concentration gradient and does require energy.
Perhaps someone who has taken bio within the last several years can correct anything I might have misstated here.
