Yes because a homogeneous mixture is a mixture that has the same uniform appearance and composition throughout while with heterogeneous you can see the different parts of the mixture and pick them out
Answer: B) The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Explanation:
The most logical third step in Connell's experimental procedure, permitting him to either accept or reject his hypothesis of competitive exclusion is the experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Balanus is a species of crustacean, as know as sea acorns, whereas Chthamalus is a species of barnacles that can easily be found in the northern hemisphere's coasts.
The answer is <span>c. One that is most easily affected by changes in water quality.
An indicator species is a biological species whose presence or absence and even abundance can indicate specific environmental conditions. For example, there are some species (plant, fish, invertebrates,...) that can live only in an extremely clean river. But, if that clean river gets polluted by human activity, the river will not be any long extremely clean, and sensitive species will not survive and will disappear from the river. Its absence will indicate that river quality is threatened.</span>
