Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
Answer:
The correct answer will be option-C
Explanation:
LUCA or the last universal common ancestor or the concestor represents one of the populations of the most common ancestor of all the organisms present on this Earth today.
The LUCA organisms are not considered the first form of life on earth but studies show that they spread their genes to all other organisms through horizontal transfer methods.
Recent studies by William F. Martin indicates that LUCA was anaerobic thermophilic, H₂-dependent, CO₂-fixing organisms, therefore, the correct answer is option-C.
