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.
Answer: cellular metabolism
Explanation:
Cellular metabolism is chemical reactions that takes place in living organisms so that they will be able to maintain life. Cellular metabolism is made up of thousands of genes, metabolites and proteins.
Cellular metabolism is affected by the sympathetic nervous system but is not affected by the parasympathetic nervous system.
The answer is Mullerian mimicry.
Mullerian mimicry is a kind of mimicry in which two or more poisonous animals generate identical presences as a shared protective tool. The theory behind this is that if a predator learns to avoid one of the poisonous species, it will also avoid the mimic species as well.
It is a natural process in which two or more often repugnant species, which may or may not be closely associated and share one or more common predators, have started to mimic each other's cautionary signals, for their communal benefit, as predators eventually learn to avoid all of them.
Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
