Answer:
atoms
Explanation:
all things in the universe are made of atoms and they are considered the fundamental unit of matter.
non-living things are composed of different compounds and molecules.
living things are made of cells, and cells themselves are made of different molecules. So living things are also made of atoms.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
Answer and Explanation:
In the case when you move outwards from a tree so there would be more growth, the reasons are as follows:
1. The block i.e. left and light near tree permits lesser photosynthesis as in the tree
2. But if you move outwards so there would be more light
3. Also it permit plants to photosynthesis that generates greater amount of glucose and proteins for growth
In this way it would be explained
