ZanzabumX [31]

Answer:

I think she should try the experiment one set with fertilizer, and one without. The negative control group would be the set of rose bushes grown without the fertilizer, but under the exact same conditions as the experimental group. Then, if a difference is seen you can be sure it's accurate, since you tested with and without fertilizer under the same conditions. Sorry if i am wrong, I am not completly sure about this one. Again I might be wrong so sorry in advance.

If no other changes occurred, how would emigration affect the population density of a group of organisms?​
valentinak56 [21]

<u>Answer:</u>

<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms. </em>

<u>Explanation:</u>

<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.

Population density is the population per unit area that is population per square kilometer.

Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration.  </em>
