I NEED HELP WITH THIS ASAP!! Describe one similarity and one difference between the two terms in each of the following pairs.

1. biosphere, ecosystem

2. hypothesis, theory

3. independent variable, constant

Explanation:

1. the similarity between biosphere and ecosystem is that they both have organisms that depend on each other and the difference is that biosphere uses every single organism while ecosystem only uses organisms that are inside of the ecosystem. 2. the similarity between theory and hypotheses is that they are both something that have to be scientifically proven and the difference is a theory relies on evidence and a hypothesis relies on a possibility. 3. a similarity between independent variable and constant is that they both change at the same time and the difference is that an independent variable is controlled or changed by the scientist while a controlled variable is one that they want to remain the same.

b. read the phase at the intersection of any given temperature and pressure.
