Answer:
The project showed no control over the confounding variable.
Explanation:
The confounding variable are variables that can influence the dependent variables and that were not established by the researchers. These variables exist naturally in the experiment and are able to alter the result of the experiment in a very intense way.
The dependent variable, in the case presented in the question above, is the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment. As we can see these two variables are being controlled by the researchers, however, the confounding variables such as soil fertility, water availability, sunlight intensity, wind intensity, are not being controlled and this can severely damage the experiment.
Why marine biology matters. ... Careers in marine biology are very important, as studying the state of oceans becomes more crucial to the study of climate change, changing biodiversity, human impact and more. Marine biologists study habitats including coral reefs, kelp forests, the open ocean and so much more
The answer is A- thylakoids
Isolation can be due to behavioral, geographical, or temporal barriers. <span>Speciation can take place in two general ways. A single species may change over time into a new form that is different enough to be considered a new species. This process is known as anagenesis. More commonly, a species may become split into two groups that no longer share the same gene pool. This process is known as cladogenesis. There are several ways in which anagenesis and cladogenesis may take place. In all cases, reproductive isolation occurs. Hope this helps! </span>
