The treatments can be compared to each other instead of to a control
In physics, dynamic force can be closely described as the amount of acceleration/velocity, usually in uniform circular rotation, needed to move an object.
There are several methods arthropods use for gas exchange; insects have holes in their segments called spiracles, connected to a trachea and tubules which deliver oxygen directly to tissues without needing to go through a bloodstream; and also remove waste gasses. Arachnids may use a type of simple lung called a book lung, comparable to a book gill in a similar stacked spatial arrangement for some aquatic arthropods. Other marine arthropods use gills for gas exchange, such as crabs and lobsters; crabs can continue to use gills on land so long as they remain moist. The simpler and smaller arthropods are able to perform gas exchange across their entire body surface and need no additional specialized gas exchange structures.

The main objective would be reliable, dependable power when needed, were needed.
The minimum number of seismographs needed to locate an epicenter of an earthquake is 3.
Controls are not needed in the arthropods experiment described in the study guide because the purpose is to observe the natural behavior or characteristic of the arthropods in their environment without any manipulation or comparison with a control group. This type of observational study does not require controls to assess the behavior or traits being studied.

Controls are not needed in the arthropods experiment because the study does not involve comparing treatments or conditions. The purpose of the experiment is simply to observe and describe arthropods in a specific environment, rather than testing a hypothesis or comparing experimental groups. Controls are typically used when comparing treatments to ensure any observed effects are due to the treatment itself and not other factors.

The full quetion is:Why are controls not needed in the arthropods experimentA some experiments cannot have controlsB All experiments must use controlsC compare treatments to each other instead of to a controlD hypothesis is not falsifiableThe treatments in this experiment can be compared to each other instead of to a control.
Controls are not needed in the Arthropoda experiment if the focus is simply on observing the behavior or characteristics of Arthropoda in a specific environment. In this case, the purpose is not to compare a treatment group against a control group, but to solely observe and record information about Arthropoda. However, if the experiment involves testing a specific hypothesis or comparing different treatments on Arthropoda, then controls would be necessary.
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
It is a conclusion,variable,a hypothesis,procedure,and data.
