EASY_LOTS OF POINTS I've just done an experiment in which I put one object into three beakers (three of the same object for each of the beakers) with different levels of acidity to record the impacts acidity has on the object.
Which is the independent variable? which is the dependent variable?

The independent variable is the beakers and the dependent variable is the object you put in the beakers.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
