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>.

How is the increase in pulse rate while carrying out vigorous activities related to the rate of oxygen intake and release of car
polet [3.4K]
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
