Animal cells do not have cell walls, nor do protozoa. Cell walls protect the cells from damage. It is also there to make the cell strong, to keep its shape, and to control the growing of the cell and plant. The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells
Answer:
The atomic number of a nucleus will go down by two in alpha decay
Answer:
Potential energy decreases because temperature is measured by the how fast molecules move. The more kinetic energy in the molecules, the less potential energy
Answer:
Kinetic energy increases because iron shavings move in the direction of magnetic force.
Potential energy decreases, and kinetic and thermal energy increase.
Potential energy increases because movement is in the opposite direction of the magnetic field.
They seek a rail line not affected by friction.
