Answer:
Electricity, gravity of earth and structure of atom provide evidence.
Explanation:
The investigation of electricity, gravity of earth and structure of atom helps the student to understand that without touching, one object apply force on another object. In electric current, we can see the property of magnetism due to which it attract and repel objects while in gravity of earth, the earth apply gravitational force to attract objects towards itself. in the structure of atom, proton present in the nucleus which attract the electron present in the shells.
Answer:
The cell will shrink
Explanation:
In an hypotonic solution, water moves into the cell through the process of osmosis. This shall be due to the high concentration of water in the hypotonic solution than that in the cytoplasm.
Due to this movement, the cell bulges out.
If the cell is transferred to a hypertonic solution, water shall move out of the cell thereby making the cell shrink. This is because water concentration in the cytoplasm shall be higher than that in the hypertonic solution.
Effect to the survey shall be an experience of the exact opposite of the previous immersion.
The answer is most likely the last option.
The growth or tuning of plant root toward or away from moisture
