1. a hypothesis and a theory are related because a. a theory is always used to develop a hypothesis b. they are both developed in the absence of observations. c. the data collected when a hypothesis is tested can support a theory. d. an experiment is done before the formation of both a hypothesis and a theory. 2.which word describes the energy in an exergonic reaction? a. created b. relased c. absorbed d. destroyed 3. whcich describes the progress of photosynthesis? a. carbon dioxide + water -> glucose + oxygen b. glucose+oxygen -> carbon dioxide+ water c. water+oxygen -> glucose+carbon dioxide d. glocose+ carbon dioxide-> water+ oxygen 4.the role of an enzyme in a chemical reaction is to change which of the following? a. the type of rection b. the activation energy of the reaction c. the ph at which the reaction occur d. the temperature at which the reaction occurs

C. the data collected when a hypothesis is tested can support a theory.  

In scientific method theory and hypothesis are two major components. A hypothesis is either a suggestion for an observable phenomenon, or a prediction of a possible relation among different phenomena. Whereas a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. So we can say that the data collected when a hypothesis is tested can support a theory.

B. released

The word Exo means out or released therefore exorgonic reactions are those reactions in which energy is released. The same reaction which allows energy release is called exothermic reaction and the energy is in the form of heat.

A. carbon dioxide + water ->glucose + oxygen  

Photosynethesis is the process in which plants make their food in the presence of sunlight. A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.

B. the activation energy of the reaction  

Enzymes are just like catalysts in an y chemical reaction. We know that catalysts are the chemicals which speeds up the reactions. In the same way enzyme speeds up the reaction and they increase the activation energy of any chemical reaction.

airlines i think? or a cruise boat? does this work out for u? ?
