The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.

You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.
Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.
Passive Transport moves molecules across membrane without the use of energy by the cell.
-Simple diffusion
-Facilitated diffusion
-Osmosis
Active Transport uses energy (ATP) to move molecules across membrane.
-Protein pumps
-Exocytosis
-Endocytosis (Phagocytosis & Pinocytosis)
I’m pretty sure it’s the refractory period!!
Hope this helps!
Answer:
C. natural selection
Explanation:
Natural selection is when the organisms that have the better adaptation so they survive. In this case, the green was the better adaptation so they lived.
The answer is A or the first one
