Three plants were grown to study the effects of nitrate and magnesium ion deficiency on their development. They were kept in the
same conditions, except for the types of minerals supplied. Use
Plant A was provided with all essential minerals.
Plant B was given all minerals except nitrate ions. Plant C was given all minerals except magnesium ions. State three conditions, other than water and the concentration of mineral ions, that would need to be kept the same for all the plants, in order to make the investigation a fair test
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
La solución isotónica significa que tiene el mismo potencial hídrico igual que la sustancia, la solución hipertónica significa que la solución tiene un potencial hídrico menor que la sustancia secundaria, la solución hipotónica significa que la solución tiene un potencial hídrico mayor que la sustancia.
The family solanaceae contributes several important food, drug and ornamental plants to human race. Hence this family is considered as economically important. Solanum species: Solanum tuberosum is most important food crop after cereals
Yes. This is because natural gases can also come from natural sources like volcanoes and cows. Cows produce tons and tons of methane each year and volcanoes release many greenhouse gasses when they erupt.
