Rama09 [41]

Finding variables in the following Students measured the temperature of the water at different depths in Lake Skywalker and foun
Natasha2012 [34]

The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is <u>depth.</u> Different depths lead to a variation in temperature. 2)<em> depths</em>.

<h3>What are de dependent and independent variables?</h3>

  • Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.

This variable is not affected by any other one but influences or causes a reaction in other variables.

  • The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.

Its response might be either directly proportional or inversely proportional to the change in the independent variable.

Now let us answer the question.

The aim of the study was probably to analyze how temperature changed with depth.

So, according to this, depth influenced on the temperatureof water.

  • The independent influencing variable is <u>depth</u>.

Sonbull [250]

Answer:

Pancreatic juice, NaHCO₃.

Explanation:

The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.

The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus.  The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.

Thus, Pancreatic juice, NaHCO₃ is the correct answer.
