Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
Answer:
The Kinetic Theory of Matter
The states that all of the particles that make up matter are constantly in motion. As a result, all particles in matter have kinetic energy. The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas.

Answer:
2. What must be done to carbon dioxide gas to change it to a solid?.
Carbon dioxide is a gas by using a metal to solidify it
3. Which is colder, dry ice or carbon dioxide gas?
Carbondioxide gas
If dry ice is placed in water, we see bubbles rise.
4. These bubbles are made of
gaseous substance in the gaseous state.
5. What happens to the size of the dry ice as the bubbling goes on?
the size of the dry ice reduces as a result of conversion of solid to liquid form
