True! because without gravity the spacecraft wouldn't go where there wanted it, in the time that they wanted it
In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.
<h3>What is a dependent variable?</h3>
A dependent variable is any type of experimental condition that is modified during the experiment.
Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).
Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).
In conclusion, the dependent variable is the rate of respiration.

Answer:
Explanation:
This question appears incomplete. However, one of the main differences (in organelles) between plants and animal cells is the absence of cell wall and chloroplast in animal cells while both organelles are present in plant cells. The cell wall is outside of the cell membrane. The cell wall provides rigidity and support to the plant cell while the chloroplast is the cellular "machinery" for photosynthesis. The chloroplast contains the green pigment called chlorophyll which provides green plants with there colour and assist the plants in absorbing/capturing of sunlight/energy for the purpose of photosynthesis (self production of food by green plants).
