Answer: Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Explanation:
As the days get shorter and the temperature drops, this bear overeats and stores food as fat to get ready for hibernation.
When hibernate, bears will keep sleeping so they won't get any food from outside so they need to collect the food before hibernating. They have to eat more food than usual and stored it as fat to keep them from starving. The fats also help keep them warm as they are insulating the heat.
<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!
Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.
Active Transport
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).
Phagocytosis
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.
Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.
Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>
Explanation:
The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

We live long lives compared to a lot of animals, we are at the top of the food chain, we are omnivores and have a larger variety of foods we can eat that’ll nurture our bodies
