Answer:
<em>The correct option is B) number of patients with brain tumors</em>
Explanation:
In a scientific experiment, an independent variable is a variable which is being changed by the scientist or changes naturally. The effect of the independent variable is studied on another variable which is termed as the dependent variable. Hence, the dependent variable can be described as the variable which is under study in a scientific experiment.
In the following scenario, as the effect of prolonged cell phones is being tested on causing brain tumors hence, the number of patients with brain tumors will be the dependent variable.
Elaborative rehearsal is a memory system that includes contemplating the significance of the term to be recalled, instead of essentially rehashing the word to yourself again and again. For instance, you have to recall the expression "neuron."
Answer:
reactions
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Biology overlaps with chemistry in studying the structure and functions of activities at the molecular level. The principles of chemistry are useful in cell biology because all living cells consist of chemicals and various chemical processes take place in many living organisms.
