Answer:
The cell will shrink
Explanation:
Osmosis is the net movement of water molecules through a semipermeable membrane like the cell membrane from a region where their concentration is low to a region of high concentration. When the external solution has a higher osmotic pressure than the cell contents, then it is said to be hypertonic. The cell was placed in a hypertonic solution. The concentration gradient between the outside and the inside makes water molecules to move through the cell membrane to the external solution. This makes the cell to shrink due to loss of water.
I think the correct answer from the choices listed above is option A. Chemoautotrophs make energy by converting <span>carbon dioxide, water, and inorganic compounds into carbohydrates. These organisms uses inorganic energy sources. Hope this answers the question.</span>
A.
The independent variable (experimental variable) is the exposure to UV lights of the tadpoles because it is being varied. The dependent variable is the survival of the tadpoles, because it is the one being affected by the independent variable.
B.
The information from the experiment does not support the hypothesis because an equal number of tadpoles remain, while the hypothesis predicted that less would remain in the tank exposed to UV light.
C.
Other factors such as temperature of the water may be affecting the frog populations.
D.
The control group was the tank covered with glass and the experimental group was the tank covered with acrylic plexiglass
E.
The difference was that one group was exposed to the UV light, while the other group was not. No, they should not be different in any other way, because that may lead to inconclusive experimental results.
Fine sediment deposited by wind is B) loess
