If you test more than one variable in an experiment at a time than you wouldn't know what variable caused the change in the end.
Answer options:
- The nucleus was unable to provide instructions for the other organelles in the cells.
- The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function.
- The lysosomes were unable to remove waste from the cells.
- The cell membrane was unable to allow substances to enter and exit the cells.
Answer:
- The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function.
Explanation:
Mitochondria are the site of aerobic respiration. This is the process that produces energy in the form of ATP. ATP provides energy for all cellular processes. Without this energy, the cell cannot carry out its functions and will quickly die.
Aerobic respiration requires a good supply of oxygen, which the grasshopper would not have had in a sealed container.
Answer: Homeostasis is a resistance to change.
Explanation: There are many other examples of homeostasis in biology, like the pH of blood and the concentration of ATP in a cell.
Answer:
C. because the common goal of basic science is to understand how things work, whether it is a cell, an organism, or a entire ecosystem.
