Answer:

If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

(20 points) [URGENT] give a hypothesis on how the mass of potato chips is expected to change in each solution
lbvjy [14]

I predict that the potato  in the lowest sugar solution

(water) will gain the most mass through osmosis, whereas the 80% sugar

concentration will lose the most mass through osmosis. I predict this

because I think that the potato chips will try to gain and lose water

between the two sides of its cell wall in order to reach an

equilibrium between them because the 80% sugar solution has a high

amount of sugar molecules, which can not diffuse through the membrane,

I think that the potato will lose water in order to make the solution

on the outside of its membrane equal to the water concentration on the

inside thus losing mass. I also predict that the other

concentrations (60%, 40%, and 20%) will lose mass, but in lower

numbers compared to the 80% sugar solution (the lower the

concentration, the higher the mass). However, since the distilled

water carries no sugar molecules, I think that the potato chip will

gain water to create a balance between the two sides of the cell wall,

making it gain mass.

FinnZ [79.3K]

Answer:

well from what i can see based on the data in the graph is that, since the accidental introduction of species 3 the population of the other 2 species has decreased quite a bit. While you can also observe that the population of population 3 continues to grow.

This suggests 3 possibilities to me

possibility 1. species 3 is consuming leaves just like the other 2 species causing a scarcity in food.

possibility 2. species 3 is consuming the other 2 species causing the decrease in population.

possibility 3. species 3 and the other species may be fighting over shelter, food, or water, causing more lizard fatalities.
