Answer:
Carrying capacity can be described as the maximum number of population of a species that a particular habitat can hold.
There are a number of events which effect the carrying capacity like:
Environmental changes like weather conditions might become favorable for a species in a habitat. It might be that a certain weather condition raises more food for a species. Hence, the carrying capacity would increase.
It might be conditions like drought make the availability of nutrients scarce for a population of species. In this case, the carrying capacity of the ecosystem would decrease.
It might happen that other species might come to live in the particular area. That species will deplete the availability of resources and cause the carrying capacity to decrease.
If adequate amount of rain fall occurs in an area, it might cause the carrying capacity of a species to increase as there will be more water. But if the water supply becomes scarce, the carrying capacity would decrease.

Explanation:
There are several reasons that genetic variation occurs. Some of them are as follows: mutation, random fertilization, recombination event during meiosis etc. The way in which this variation in genetics is distributed is in a continuous way. In case of the human species, it is reported that 85% of all variation is within a certain population, while the remaining 15% of genetic variation is between populations.
Answer:
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
