Osmosis is the diffusion of water in high to low concentration. It doesn’t use energy. It helps equal out the solute concentration.
That question, this incomplete. The full question is:
3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What are the dependent variables, independent and the controlled variable of this experiment?
Answer:
- Independent variable: different humidity levels
- Dependent variable: the heights of the trees
- controlled variable: the types of trees
Explanation:
An independent variable is one that exerts an influence within the experiment and can be measured, acting on other elements to promote the observation of a result. As the experiment seeks to observe the influence of humidity on the height of the tree, we can say that humidity is the independent variable.
Dependent variable is that which is influenced by the independent variable to generate a result that can be observed, can also be measured. As the experiment wishes to analyze how the height of the trees was affected by the level of humidity, we can say that the height of the trees is the dependent variable.
Controlled variable is that which is present in the experiment in a constant and equal way, cannot be measured. This variable is the type of trees.
The water cycle is a system that shows how the water moves around in different states to transport itself. It uses different states which show a different transportation such as evaporation or condensation. The water cycle can also use continuous movement above and below the earths surface. There are five main steps to the water cycle which are evaporation, condensation, precipitation, transpiration, and runoff but there are still many more.
Hope this helps! :)
Answer:
1) Brown, 2)Tall with a 25% chance of short 3) Rough 4) 50% chance of solid 50% chance of stripes
Explanation:
The big letters are the dominant. Dominant always shows up if its part of it. The genetic squares show that any square with a Big letter will present the big letters trait. i didnt really understand so i hope this is what you're looking for
