Answer:
The correct answer is -
Independent variable - change in the concentration of carbon dioxide
Dependent variable - bubbles produced
Explanation:
The independent variable of an experiment or study is a variable that is subject to change or being manipulated during the study to find the response on the dependent variable. The concentration of carbon dioxide is here manipulated to find the change in the amount of bubble produced.
The dependent variable is a response that is carried out by the change or manipulation of the independent factor. In this case amount of bubbles is the dependent variable.
Thus, the correct answer is -
Independent variable - change in the concentration of carbon dioxide
Dependent variable - bubbles produced
<span>The correct option is A. SI unit is the standard measure by which a measurement is made all over the world. Length is a measurement, its SI unit is meter and the tool used to measure it is ruler. The other options are wrong because, temperature is measured in kelvin, weight is measured in kilogram and volume in cubic meter.</span><span />
C, It causes the cell membrane to rupture.
There appears to still be a lot of debate within science over whether humans or climate change were primarily responsible for the extinction of many of the large mammals during this period. One hypothesis supporting the link to early human hunters is that large animals in sub-Saharan Africa co-evolved with humans as they learned how to use tools and developed ever more effective weapons. When early humans moved into Europe and Asia, taking with them their weapons and hunting skills, the populations of large animals in those areas were not accustomed to human hunting, and were therefore easy prey.
