True
DNA are cells that carry genetic codes and are passed down through generations of offspring. New cells can only arise from existing cells!
The magnetic force decreases.
Answer:
The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.
Explanation:
Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.
Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.
Can be caused by radiation.
Since the water concentration (also the water potential) is lower than the cell inside, the water will most likely flow from the cell out to the outside. This is because of osmosis, where the rule is water molecules will flow from a region of higher water potential to a region of lower water potential, through a semi permeable membrane (cell membrane).
When the cell looses water, depending its whether a animal or plant cell, if it's an animal cell, it'll shrink. If it's an plant cell, since there is the presence of the cell wall, the cell membrane will detach from the cell wall, and this phenomenon is called plasmolysis.
