List the steps of how a squirrel hibernates.
hoa [83]

Answer:

1. First of all, a squirrel would make sure to stash lots of food before and during the winter.

2. The squirrel would claim its own tree hollow/burrow.

3. They wrap themselves into a tight ball and go into a state of torpor (Torpor is a state where their body temperature becomes about the same temperature as their surrounding hibernaculum. This causes their heart rate to slow and causes them to use less energy)

4. Squirrels get up after 20 or so days to rewarm themselves up, and perhaps eat something to regain their energy. After that they will head back to their hibernaculum to continue hibernation.

5. When spring approaches they will fully wake up, go eat, regain their energy, and prepare themselves for the mating season.

Hope this helps :)

What type of change is boiling water? why
Rasek [7]
Boiling water is a physical change. This is because the water that is being changed into a gas, and can be changed back. Bohr proposed a theory that helped make the blueprint for the atomic model. Gold is a soft but heavy metal, and reflects light with a green/blue hue. Gold is a shiny yellow to canary yellow in colour, and is often confused with pyrite, or 'fool's gold'. The particles in a solid vibrate in place, and are very close together. When one atom of carbon and two of oxygen meet, the make a bond that in turn creates CO2 or carbon dioxide. I hope I helped. :)
