Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
The answer is A. Fertilizer
The other answer choices don't make sense Herbicide is a poison that kills plants, Pesticide is an insect killer, while a Growth Hormone is designed to help the plant grow not to put nutrients into the soil.
A is the correct answer!
- water can moderate temperature v. well that's why it's used as a cooling agent
- water expands upon freezing (that's why ice floats on water!)
The correct answer is Q78.0.
Diagnosis code is a tool used to group and identify diseases, disorders, symptoms, injuries and other reasons for patient encounters. Diagnostic coding is the translation of written descriptions of diseases, into codes from a particular classification.
