For this activity, you'll need a small container, such as a cup, mug, or small box. You'll also need small objects to act as particles. The objects can be anything you have on hand, such as coins, paper clips, marbles, or hard candies.
Part A
Fill the container to the top with the particles. Place your hand tightly over the top of the container and shake it. What
state of matter does this represent? Explain.

Explanation:

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
