The question is incomplete. The complete question is as follows:
Dieffenbachia plants usually grow well without fertilizer. A student wanted to see if adding liquid fertilizer would make a difference in the growth of the plant. Three plants were placed in the same type of pot with the same type of soil. Two plants received fertilizer and one plant did not. All plants received the same amount of light and water during the experiment.She watched the plants grow over a period of 30 days, only adding the same amount of water to each plant on a weekly basis. What variable is NOT being controlled in this experiment?
Answer:
Amount of fertilizers.
Explanation:
Fertilizers may be defined as the chemicals that are required to increase the quality and quantity of the crops. The chemical fertilizers may cause environment pollution.
The experiment given in the question explains the different conditions at which the plant was grown. The controlled variable is the substance whose value is known and being constant in the experiment. In this experiment, the fertilizer is randomly given to the plant and its value is unknown. So we can say that the fertilizer is not a controlled variable in the experiment.
Thus, the correct answer is amount of fertilizers.
The oxygen released in photosynthesis comes from split water molecules
Answer:
The controversial scientific process of cloning, organisms are created that are genetically identical to the parent. This process would be classified as <em>asexual reproduction.</em>
Explanation:
Asexual reproduction can be described as a process of reproduction in which daughter cells are produced which are identical to the parent cell. In the process of cloning, identical copies of a cell, tissue, organ or individuals are produced. We can say that both these terms are similar to each other. Hence, both the processes of asexual reproduction and cloning can be termed as similar as identical copies are produced in both the processes.
