Answer:
7) the environment is hypotonic because it is less concentrated than the inside of the cell
8.)the mass would decrease because the stuff inside the cell (which is more concentrated in comparison) would diffuse across the cell membrane into the environment in order to maintain equilibrium
9.) Diffusion in order to maintain equilibrium (moving things across a barrier from a more concentrated area to a less concentrated area in order to have an equal concentration on each side) does not require energy. However, moving matter out of the cell in Diagram C would require energy because it involves moving mass from a less concentrated area to a more concentrated area.
Explanation:
Herbivores. The eat directly from the producers. 10% of the producer's energy goes to herbivores, while only 10% of the 10% energy the herbivores had goes to carnivores.
A.Humans use their knowledge to locate resources for them selves thereby reducing competition among them
The average distance is 16,000 km
Converging rate is 10 cm/year
1 km = 100,000 cm
= 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
