Why is the amount of fertilizer known as the independent variable?

Answers

Answer 1

Answer:

You can think of an independent variable is the variable that is being varied by you the experimenter or scientist; it is the input/"cause"/the tunable variable. A dependent variable is the response/output/"effect".

There is also the control variable, which are variables that stay constant throughout. You generally have only one independent variable and many control variables so that you can properly disentangle cause and effect.

A simple example might be say you want to know if a certain brand of fertilizer helps your crops grow. You want to see how much fertilizer you need for optimal growth without using too much. What is the independent and dependent variable? (Highlight below for the answer!)

The independent variable is the amount of fertilizer you put on the crop. It is the variable that you, as the tester, vary yourself. The dependent variable is how much your crop grows. What about the control? It is the crop you choose to use the fertilizer on (e.g., corn, wheat, peas). Certainly, comparing the influence of fertilizer between corn and peas would not definitely tell you whether the fertilizer is effective; if you compared two different crops, you would have other confounding variables out of your control, so you want to test it only on one crop at a time.

I put cause and effect in quotes because you may run into one of many cause/effect fallacies (or mistaken beliefs). It is possible (and often happens in research) where you plot what you think is an independent and its dependent variable, but the reality is quite different! There are two common types- spurious relationships and spurious correlations. A spurious relationship is one in which a direct cause/effect relationship is concluded incorrectly when in fact there is a lurking or hidden variable unaccounted for. One commonly cited example is say you find an increase of death by drownings and ice cream sales. It would be incorrect to infer that eating more ice cream causes more drownings, or vice versa. The lurking variable that can explain both is hot weather (i.e., people eat more ice cream and go swimming more to cool down). A spurious correlation is incorrectly inferring the extent of how related two variables are (not necessarily a cause/effect relation, but something used often in statistics). Here is a website that illustrates quite ridiculous correlations (a pet project of a graduate student), emphasizing that correlation is not causation.

Compare the inputs and outputs of humans and robots in terms of matter and energy.

Answers

Answer: In contrast to human stance control, robot stance control is at an early stage of evolution. The need for some form of stance control system has been recognized during the recent rapid development of humanoid robots (see Mahboobin et al., 2008). However, the design of most robot balance systems has not taken advantage of existing knowledge of human stance control systems. A possible reason for this is that engineers focused on the obviously important interaction that occurs at the interface between the robot’s feet and the ground

The filter works by marking the sharp edge boundaries of the image, the edge between a subject and the contrasting color background, and increasing the image contrast in the area around the edge.

All living things respond to stimuli.

All living things maintain homeostasis.

All living things adapt to changes in their environment.

All living things contain genetic material and reproduce.

The correct answer would be that all living things adapt to changes in their environment.

Generally, all living organisms try to adapt to changing environments. Those that are able to successfully adapt survive in the environment and are able to produce offspring that are also able to survive in the same environment. Organisms that are not able to adapt to a changing environment end up dying from the population. This is an example of evolution by natural selection - the survival of the fittest.

Which action would most likely increase the amount of carbon in the environment? A. Choosing to burn coal to generate electricity B. Using energy-efficient appliances in place of older, traditional appliances C. Reusing shopping bags instead of using disposable plastic bags D. Recycling paper and plastic instead of throwing it in the trash

Answers

Answer:

Choosing to burn coal to generate electicity

Explanation:

Burning coals to generate electricity is most likely to increase the amount of carbon in the environment because it emits carbon dioxide, hence option A is correct.

Why does burning coals increase the amount of carbon?

When coal burns its carbon is combined with oxygen to produce more amount of carbon dioxide, for generating electricity coal burns is producing a large amount of carbon.

If fuel burns its oxygen reacts with carbon in the air forming carbon dioxide or reacts with hydrogen to form water vapor.

Using energy-efficient appliances in place of older, traditional appliances, has less chance to produce excess amounts of carbon in the environment.  Recycling things also reduces the amount of carbon in the environment.

Therefore, choosing to burn coal to generate electricity is the correct option.

Explanation:

The independent variable is one whose value is often manipulated during the course of experiments and the effects produced by the manipulation is measured on the dependent variable.

The dependent variable is the actual variable that is being measured in the course of experiments. The value of the dependent variable is affected by changing the values of the independent variable.

Constants are variables whose values remain unchanged throughout the course of experiments.
