Sammy is taking notes to study for a test. he wrote out the steps that involve hydrogen during photosynthesis. the steps are shown, but they are not in the correct order. 1 - water is broken down into oxygen and hydrogen. 2 - glucose is broken down to be used by plants. 3 - hydrogen combines with carbon dioxide to form glucose. 4 - hydrogen enters the plant as part of water. which lists the correct order of the steps? 4, 2, 1, 3 4, 1, 3, 2 4, 3, 1, 2 4, 2, 3, 1

The order will be : 4, 1, 3, 2

Explanation:

The correct order of photosynthesis steps is

a) Hydrogen enters the plant as part of water.

b) Water is broken down into oxygen and hydrogen: thus water is source of oxygen in photosynthesis

c) Hydrogen combines with carbon dioxide to form glucose: the source of carbon in glucose is carbon dioxide.

d) Glucose is broken down to be used by plants: this gives energy

so what is the problem with your lab report and whats the subject of the lab report? i will you

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
