Answer:
That is administered and controlled
Step-by-step explanation:
A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.
If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.
The endosymbiotic theory hypothesizes that mitochondria and chloroplasts were formed when <u>prokaryotic </u>cells were engulfed by larger cells that were precursors to <u>eukaryotic </u>cells.

Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
