Cells that have no mitochondria are unable to convert oxygen into energy, found in the form of adenosine triphosphate (ATP). All multicellular eukaryotic organisms, including plants and animals, have mitochondria in some cells, but prokaryotes and some single-cell eukaryotes do not have mitochondria.
If a cell can't produce energy, it would be unable to perform vital processes, leading to its death. On an organism level, inability to produce energy in a significant number of cells can lead to system failures and potentially, premature death.
If a cell cannot produce energy, over time, it would not be able to carry out critical functions such as growth, repair, transportation of nutrients, and reproduction. This condition could lead to the cell's eventual death. In an organism, if a sufficient number of cells are unable to produce energy, it could lead to system failures and ultimately, premature death of the organism. This is because the working of an organism depends on the collective effort of its cells which require energy to function.

Answer:
The dependent variable was the mass of the dialysis tubing after sitting in the beakers containing the mystery solutions.
Explanation:
Reptiles have a special egg that feeds their young called an amniotic egg. Therefore, option (B) is correct.
Reptiles, birds, and certain mammals reproduce on land thanks to the amniotic egg's extraordinary evolution. Its shell protects the embryo from external dangers and desiccation. The amnion, which encloses the embryo in a fluid-filled chamber, is a key element of the amniotic egg. Amniotic fluid protects the embryo from mechanical shocks and allows gas exchange.
Reptiles can lay eggs on land without returning to water thanks to the amniotic egg, which marks the transition from aquatic to terrestrial life. This adaptability has helped reptiles colonise different ecosystems worldwide. Therefore, option (B) is correct.
