Answer: Fertilizer

Explanation:

Independent variable can be defined as the factor which can be controlled by the person performing the experiment.

The experimenter can control whether he will put fertilizer in soil or not. The growth of tulips will depend on the fertilizer as it is a source of nutrient to the plant.

here, the hypothesis will be either accepted or rejected based on the result of experiment.

In what way can open-mindedness interfere with scientific progress
umka2103 [35]
<span>Open-mindedness does interfere with scientific progress as it can lead to acceptance of untested ideas. Open-mindedness can lead to actually accepting results that are not true. This is not a great angle for people involved with scientific experiments. Open-mindedness should be limited to the fact that the results can lead to negative answers. People that can accept this theory will ultimately succeed in their strive for creating something new. There is nothing wrong in discarding the results that does not seem to fit the bill.

The Na+/K+ ATPase pump is an example of active transport, which requires energy to move substances from a higher concentration t
Afina-wow [57]

Answer:

False

Explanation:

Active transport is one of the two major kinds of transport (the other being passive transport). Active transport involves moving substances against their concentration gradient i.e. from where they are low in concentration to where they are high in concentration. Hence, energy input in form of ATP is required by the cell to make this occur.

As stated in this question, the Na+/K+ (sodium-pottasium) ATPase pump is an example of active transport, which requires energy to move sodium ions. However, in active transport, substances are moved from a lower concentration to a higher concentration and not otherwise as depicted in this question, hence, it is FALSE.
