A group of students wants to investigate the effect of the concentration of salt in salt solution (2, 5, 10, 15%) on the growth of the mint plant after three weeks of planting. Write a procedure helping the students to carry out their investigation.

The procedure is present below.

Explanation:

Take four pots having mint plant with same sizes and then apply 2% salt to pot no.1, then apply 5% salt to pot no.2, apply 10% salt to pot no.3, and apply 15% salt to pot no.4. After a 1 week or 2, see the growth of the mint plants. You will notice some mint plants are not effected to salt concentration because they are present in low quantity whereas some plants experience stunted growth due to higher concentration of salt which is unbearable for the mint plant.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
