What statement best describes how most galaxies generally move?

Most galaxies generally move away from each other due to the expansion of the universe, a phenomenon observed through the redshift of light from distant galaxies. This movement is described by Hubble's Law, which states that the recessional velocity of a galaxy is proportional to its distance from us. However, within galaxy clusters, gravitational interactions can cause galaxies to move closer together, and some may even collide or merge. Overall, the large-scale motion of galaxies is predominantly influenced by the expansion of space itself.

Which change in the procedure would most improve the validity of conclusions based on investigations?

To improve the validity of conclusions based on investigations, implementing a control group would be most beneficial. This allows for comparison between the experimental group and a baseline, helping to isolate the effect of the independent variable.

Finally, conducting multiple trials can increase the robustness of the findings.

How is the drop position related to the speed of the car the first time it passes through the photogate (before bouncing)?

The drop position is related to the speed of the car as it passes through the photogate because the speed determines how quickly the car travels from the drop point to the photogate. If the car is released from a higher drop position, it gains more gravitational potential energy, converting it to kinetic energy and resulting in a higher speed as it reaches the photogate. Consequently, the distance from the drop position to the photogate influences the speed; a shorter distance typically allows for less acceleration time, resulting in a slower speed when passing through the photogate.

Why would an animal cell shrivel up when you place water in it and concentrated in salt?

An animal cell would shrivel up when placed in a solution with high salt concentration due to osmosis. Water moves from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (the surrounding salty solution) to balance the solute levels. This loss of water from the cell causes it to shrink or shrivel.
